But whatever be the theory of the mode of inheritance, or the mechanism by which the germinal plasm of an individual is made up, it is plain that there is correlation between the various qualities of an individual due to the mode of origin of its germ plasm as a selected individual portion of the parental germ plasm.

It is to be noticed, however, that the Mendelian conceptions are in no sense an alternative to Darwinism; at the most they would serve to assist in explaining the mechanism of variation, and by enlarging our idea of the factors, increase the rate at which we may suppose selection to work.

Darwin certainly was impressed with the view that natural selection and variation together formed a mechanism, the central product of which was adaptation.

Yet they must have something to develop from, and thereupon Aristotle gives an account of a process in the psychological mechanism which he illustrates by comparative psychology, wherein a Xo yos or meaning emerges, a "first" universal recognized by induction.

On the other we have a stage at which the rational but as yet not reasoned concepts developed in the medium of the psychological mechanism are subjected to processes of reflective comparison and analysis, and, with some modification, maintained against challenge, till at length the ultimate universals emerge, which rational insight can posit as certain, and the whole hierarchy of concepts from the " first " universals to Ta apEA are intuited in a coherent system.

Axioms, on the other hand, in which the sciences interconnect" through the employment of them in a parity of relation, seem to be implicit indeed in the psychological mechanism, but to come to a kind of explicitness in the first reflective reaction upon it, and without reference to any particular content of it.

The relation, then, of the two orders of principle to the psychological mechanism is different.

There is in the first place the action of the psychological mechanism in the process from discriminative sense upwards wherein we realize " first " universals.

It is only then in the rather mystical relation of vous to the first type of induction as the process of the psychological mechanism that an indication of the direction in which the bridge from individual being to universal knowledge is to be found can be held to lie.

It is true, of course, that ultimate laws need discovery, that they are discovered in some sense in the medium of the psychological mechanism, and that they are nevertheless the grounds of all specific inferences.

In the second, there is no claim that thought at one and the same time imposes form on " the given " and is susceptible of treatment in isolation by logic. With Herbart the forms of common experience, and indeed all that we can regard as his categories, are products of the psychological mechanism and destitute of logical import.

Were this all, the gain by their introduction would consist mainly in a clearer insight into the mechanism of co-ordinate systems, rectangular or not - a very important addition to theory, but little advance so far as practical application is concerned.

At first sight this singular structure appears so like a deformity that writers have not been wanting to account it such, 2 ignorant of its being a piece of mechanism most beautifully adapted to the habits of the bird, enabling it to extract with the greatest ease, from fir-cones or fleshy fruits, the seeds which form its usual and almost invariable food.

The particular case where both centrodes are circles is specially important in mechanism.

The frame is a structure which supports the pieces of the mechanism, and to a certain extent determines the nature of their motions.

The foi-m and arrangement of the pieces of the frame depend upon the arrangement and the motions of the mechanism; the dimensions of the pieces of the frame required in order to give it stability and strength are determined from the pressures applied to it by means of the mechanism.

It appears therefore that in general the mechanism is to be designed first and the frame afterwards, and that the designing of the frame is regtilated by the principles of the stability of structures and of the strength and stiffness of materials,care being taken to adapt the frame to the most severe load which can be thrown upon it at any period of the action of the mechanism.

Definition and Division of the Theory of Machines.From what has been said in the last section it appears that the department of the art of designing machines which has reference to the stability of the frame and to the stiffness and strength of the frame and mechanism js,a branch of the art of construction.

But in studying or treating of, the theory of machines, the order of simplicity is the best; and in this order the first branch of the subject is the modification of motion and force by the train of mechanism; the next is the effect or purpose of the machine; and the last, or most complex, is the action of the prime mover.

Robert Willis (1800-1875) has the merit of having been the first to simplify considerably the theory of puie mechanism, by pointing out that that branch of mechanics relates wholly to comparative motions.

General Principle.A mass of fluid is used in mechanism to transmit motion and force between two or more movable portions (called pistons or plungers) of the solid envelope or vessel in which the fluid is contained; and, when such transmission is the sole action, or the only appreciable action of the fluid mass, its volume is either absolutely constant, by reason of its temperature and pressure being maintained cisrnstant, or not sensibly varied.

Motions ClassedIn problems of mechanism, each solid piece of the machine is supposed to be so stiff and strong as not to undergo any sensible change of figure or dimensions by the forces applied to ita supposition which is realized in practice if the machine is skilfully designed.

The most common forms for the paths of the points of a piece of mechanism, whose motion is simple shifting, are the straight line and the circle.

In mechanism it is usually the central line either of a rotating shaft or axle having journals, gudgeons, or pivots turning in fixed bearings, or of a fixed spindle or dead centre round which a rotating bush turns; but it may sometimes be entirely beyond the limits of the turning body.

DefinitionsAn elementary combination in mechanism consists of two pieces whose kinds of motion are determined by their connection with the frame, and their comparative motion by their connection with each otherthat connection being effected either by direct contact of the pieces, or by a connecting piece, which is not connected with the frame, and whose motion depends entirely on the motions of the pieces which it connects.

The first systematic classification of elementary combinations in mechanism was that founded by Monge, and fully developed by Lanz and Btancourt, which has been generally received, and has been adopted in most treatises on applied mechanics.

But that classification is founded on the absolute instead of the comparative motions of the pieces, and is, for that reason, defective, as Willis pointed out in his admirable treatise On the Principles of Mechanism.

From this principle arise problems of a kind which will be referred to in treating of Trains of Mechanism.

General Principles.A train of mechanism consists of a series of pieces each of which is follower to that which drives it and driver to that which follows it.

Hence one or both of the shafts must have a vibratory and unsteady motion, injurious to the mechanism and framework.

One train of mechanism may diverge into two or moreas when a single shaft, driven by a prime mover, carries several pulleys, each of which drives a different machine.

General Pr-inciples.----Willis designated as aggregate combinations those assemblages of pieces of mechanism in which the motion of one follower is the resultant of component motions impressed on it by more than one driver.

It is seldcm that one of these effects is produced without at the same time producing the other; but the classification of Willis depends upon which of those two effects, even supposing them to occur together, is the practical object of the mechanism.

The seventh link AF is equal in length to hair the distance EA when the mechanism is in its central position.

In a five-bar chain a point, as a, in a link non-adjacent to the fixed link has two degrees of freedom and the chain cannot therefore be used for a mechanism.

In order to convert a chain into a mechanism it is necessary to fix one link in it.

What was the fixed framework of the mechanism in one case becomes a moving link in an inversion.

The Reuleaux system, therefore, consists essentially of the analysis of every mechanism into a kinematic chain, and since each link of the chain may be the fixed frame of a mechanism quite diverse mechanisms are found to be merely inversions of the same kinematic chain.

Kennedy (London, 1886), the system was used for the first time in an English textbook, and now it has found its way into most modern textbooks relating to the subject of mechanism.

It will be understood that there is a new velocity diagram for every new configuration of the mechanism, and that in each new diagram the image of the rod will be different in scale.

These several images are not to the same scale, so that although the images may be considered to form collectively an image of the chain itself, the several members of this chain-image are to different scales in any one velocity diagram, and thus the chainimage is distorted from the actual proportions of the mechanism which it represents.

In applying this principle to the drawing of an acceleration diagram for a mechanism, the velocity diagram of the mechanism must be first drawn in order to afford the means of calculating the several radial accelerations of the links.

Then assuming that the acceleration of one point of a particuar link of the mechanism is known together with the corresponding configuration of the mechanism, the two Vectors Ac and ct can be drawn.

Examples, completely worked out, of velocity and acceleration diagrams for the slider crank chain, the four-bar chain, and the mechanism of the Joy valve gear will be found in ch.

Forces applied to Mechanism Classed.If 0 be the obliquity of a force F applied to a piece of a machinethat is, the angle made by the direction of the force with the direction of motion of its point of applicationthen by the principles of statics, F may be resolved into two rectangular components, viz.

It is shown that a machine may at any instant be represented by a frame of links the stresses in which are identical with the pressures at the joints of the mechanism.

Incidentally the method gives the pressures at every joint of the mechanism.

The prejudicial resistances are generally functions of the useful resistances of the weights of the pieces of the mechanism, and of their form and arrangement; and, having been determined, they serve for the computation of the lost work, which, being added to the useful work, gives the expenditure of energy required.

These velocity ratios are known by the construction of the mechanism, and are independent of the absolute speed.

Balanced Lateral Pressure of Guides and Bearings.The most important part of the lateral pressure on a piece of mechanism is the reaction of its guides, if it is a sliding piece, or of the bearings of its axis, if it is a turning piece; and the balanced portion of this reaction is equal and opposite to the resultant of all the other forces applied to the piece, its own weight included.

Friction-CouplingsFriction is useful as a means of communicating motion where sudden changes either of force or velocity take place, because, being limited in amount, it may be so adjusted as to limit the forces which strain the pieces of the mechanism within the bounds of safety.

Of this kind is the weight of any piece in the mechanism whose centre of gravity alternately rises and falls; for during the rise of the centre of gravity that weight acts as a resistance, and energy is employed in lifting it to an amount expressed by the product of the weight into the vertical height of its rise; and during the fall of the centre of gravity the weight acts as an effort, and exerts in assisting to perform the work of the machine an amount of energy exactly equal to that which had previously been employed in lifting it.

But if the effort and the resistance be alternately in excess, the uniformity of speed may still be preserved by so adjusting some moving weight in the mechanism that when the effort is in excess it may be lifted, and so balance and employ the excess of effort, and that when the resistance is in excess it may fall, and so balance and overcome the excess of resistancethus storing the periodical excess of energy and restoring that energy to perform the periodical excess of work.

In balancing the mechanism of a steam engine it is often sufficiently accurate to consider the motion of the pistons as simple harmonic, and the effect on the framework of the acceleration of the connecting rod may be approximately allowed for by distributing the weight of the rod between the crank pin and the piston inversely as the centre of gravity of the rod divides the distance between the centre of the cross head pin and the centre of the crank pin.

When but one flywheel is used, it should be placed in as direct connection as possible with that part of the mechanism where the greatest amount of the periodical excess originates; but when it originates at two or more points, it is best to have a flywheel in connection with each of these points.

When the link forms part of a mechanism the respective accelerations of two points in the link can be determined by means of the velocity and acceleration diagrams described in 82, it being understood that the motion of one link in the mechanism is prescribed, for instance, in the steam-engines mechanism that the crank shall revolve uniformly.

I28.* The Connecting Rod Problem.A particular problem of practical importance is tbe determination of the force producing the motion of the connecting rod of a steam-engine mechanism of the usual type.

Unless there is some special reason for using impact in machines, it ought to be avoided, on account not only of the wasteof energy which it causes, but from the damage which it occasions to the frame and mechanism.

And the operations of placing and shifting the weights must be effected by mechanism which will enable this to be done without opening the case or exposing the machine.

Of course the introduction of automatic mechanism introduces friction and other complications, and it is difficult to construct automatic machines that shall be as accurate in their weighing as the simpler weighing machines, but in many weighing operations a moderate degree of accuracy will suffice, and speed is of great importance.

The weights and money values are arranged on a vertical chart, the sides of which converge towards the pivoting centre of an index arm which is actuated by the weighing mechanism.

The clutch mechanism is freed at the proper time by the action of the vertical rod at the end of the beam, and the brushes then he 4-lb weight is being lifted.
