The eyepiece slides into the tube cd, which screws into the brass ring ef, through two openings in which the oblong frame, containing the micrometer slides, passes.
In the process ef cell-fusion the cell-wall swells slightly and then begins to dissolve gradually at some one point.
His defence, at first only a pamphlet, became in its third edition a lengthy treatise entitled Inquiry into the Relation of Cause and Ef f ect, and is a fine specimen of Brown's analytical faculty.
Since the amounts of heat supplied at constant pressure from E to F and from E to C are in the limit proportional to the expansions EF and EC which they produce, the ratio S/s is equal to the ratio ECÃ†F.
EF is the change of volume corresponding to a change of pressure BE when no heat is allowed to escape and the path is the adiabatic BF, EC is the change of volume for the same change of pressure BE when the path is the isothermal BC. These changes of volume are directly as the compressibilities, or inversely as the elasticities.
I) be a small portion of a bell which vibrates to and fro from CD to EF and back.
As AB moves from CD to EF it pushes forward the layer of air in contact with it.
As AB returns from EF towards CD the layer of air next to it follows it as if it D E F were pulled back by AB.
As AB again moves from CD towards EF another compression or push is sent out, as it returns from EF towards CD another extension or pull, and so on.
At the instant that the original wave reaches F the wave from E has travelled to a circle of radius very nearly equal to EF-not quite, as S is not quite in the plane of the rails.
I saw the rooster strut around the chicken's area every morning.

With further transfer of the carbon from the graphitic to the combined state, the matrix itself grows weaker (EF); but this weakening is offset in a measure by the continuing decrease of discontinuity due to the decreasing proportion of graphite.
Any number of points on the parabola are obtained by taking any point E on the directrix, joining EG and EF and drawing FP so that the angles PFE and DFE are equal.
The rods BC and DB carry two small rods EF, GF jointed at F; at this joint there is a pin which slides in a slot on the rod BH, which is normal to the mirror X.
Rods EF, GF are such that Befg is a rhombus.
Siace E2 + if + ~1, or ef, is necessarily an absolute invariant for all transformations of the (rectangular) co-ordinate axes, we infer that XE + un + v~ is also an absolute invariant.
Moreover, if we draw DE parallel to DE, and EF B D parallel to EF, the lines CC, DD, EE, FF will represent on the same P ~, scale the virtual velocities of the, v~.._ points C, D, E, F, respectively,, ,.~ .--..~_ turned each through a right angle.
Tire more general property of the mechanism corresponding to proper tions between the lengths FA and EF other than that of equality is that the curve described by the point C is the inverse of the curve described by A.
F = T1 Ti = T1 (I ef9) Ta(ef 1)j When a belt connecting a pair of pulleys has the tensions of its two sides originally equal, the pulleys being at rest, and when the pulleys are next set in motion, so that one of them drives the other by means of the belt, it is found that the advancing side of the belt is exactly as much tightened as the returning side is slackened, so that the mean tension remains unchanged.
To express this symbolically, let Wi, W2 be the weights of the bodies; P the effort exerted between them; S the distance through which it acts; R1, Rf the resistances opposed to the effort overcome by Wi, ~AT2 respectively; E1, Ef the shares of the whole energy E exerted upon Wi, W2 respectively.
Then E: E1 Ef V~f(PR,) +W,(P Ri), PR1.

The lowering of tension, which follows the condensation of the vapour, is then strikingly shown by the sudden precipitation of the water.] Ef f ect of Surface-tension on the Velocity of Waves.
