**D**the distance of the object, the angle subtended by AP is E/**D**, and the angular resolving power is given by X/2**D**sin a = X/2 R (3) This method of derivation (substantially due to Helmholtz) makes it obvious that there is no essential difference of principle between the two cases, although the results are conveniently stated in different forms. In the case of the telescope we have to deal with a linear measure of aperture and an angular limit of resolution, whereas in the case of the microscope the limit of resolution is linear, and it is expressed in terms of angular aperture.The distance f i, which the actual focal length must exceed, is given by

**d**(f1 2 R2) x; so that f1 = 2 R2/X (1) Thus, if X = p j, R= i ?, we find f1= 800 inches.If now we suppose the aperture AB to be covered by a great number of opaque strips or bars of width

**d**, separated by transparent intervals of width a, the condition of things in the directions just spoken of is not materially changed.We conclude that, with a grating composed of transparent and opaque parts, the utmost light obtainable in any one spectrum is in the first, and there amounts to I/wr 2, or about 6, and that for this purpose W a and

**D**dx dy dz is DZ dx dy dz, being everywhere parallel to the axis of Z, the only change required in our equations (I), (2) is the addition of the term Z to the second member of the third equation (2).Since the dimensions of T are supposed to be very small in com

**D**= b 2 kD cos nt; and to this force acting over the whole of the plane the actual motion on the positive side may be conceived to be due.The

**D**, then it is readily seen that, if DB be the path of the reflected ray, the angle ADB equals 2r, i.e.The total deviation of the ray is consequently given by

**D**=2(i - r) +7r - 2r.Similarly it may be shown that each internal reflection introduces a supplementary deviation of 7r - 2r; hence, if the ray be reflected n times, the total deviation will be

**D**=2(i - r) +n (7r - 2r) .The Platonic testimony, if it proved anything, would prove too much, namely, that the doctrine of the unity of Being originated, not with Xenophanes, but before him; and, in fact, the passage from the Sophist no more proves that Plato attributed to Xenophanes the philosophy of Parmenides than Theaetetus, 160

**d**2 E/d0dv, if we differentiate the first with respect to v and the second with respect to 0.The energy E and the total heat F are functions of the temperature only, by equations (9) and (I I), and their variations take the form dE = sdO,

**d**F = Sd0.It is found by experiment that the change of pv with pressure at moderate pressures is nearly proportional to the change of p, in other words that the coefficient

**d**(pv)/dp is to a first approximation a function of the temperature only.In this case the condition of flow is simply that of constant total heat, or in symbols,

**d**(E+pv) =0.We have therefore, by equation, (11), Sd0 = (Odv/d0 - v)

**d**p,.The value of the angular coefficient

**d**(pv)/dp is evidently (b - c), which expresses the defect of the actual volume v from the ideal volume Re/p. Differentiating equation (17) at constant pressure to find dv/do, and observing that dcldO= - nc/O, we find by substitution in (is) the following simple expression for the cooling effect do/dp in terms of c and b, Sdo/dp= (n+I)c - b..In the limiting case of a long fine tube, the bore of which varies in such a manner that U is constant, the state of the substance along a line of flow may be represented by the line of constant total heat,

**d**(E+pv) = o; but in the case of a porous plug or small throttling aperture, the steps of the process cannot be followed, though the final state is the same.The value of Od4 is then the same as

To this collar is attached a slow-motion screw, working against a reaction spring, by which the plate rr can be rotated through a small arc. The upper plate carrying two, three .or four verniers vv is attached to a vertical coned pillar passing through the centre of the larger pillar and rotating in it; this plate can be clamped to the lower plate by means of the screw C, and can be rotated with respect to it by the slow-motion screw

**d**B, as far as it goes (to 977), is identical with C, both having been copied from a common original, but A, C,

**D**, E have every right to be treated as independent chronicles.The main points of difference are that in

**D**, E (1) a series of northern annals have been incorporated; (2) the Bede entries are taken, not from the brief epitome, but from the main body of the Eccl.The impulse given by Alfred was continued under Edward, and we have what may be called an official continuation of the history of the Danish wars, which, in B, C,

**D**extends to 915, and in A to 924.After 915 B, C insert as a separate document a short register of Mercian affairs during the same period (902-924), which might be called the acts of Ã†thelflaed, the famous "Lady of the Mercians," while

**D**has incorporated it, not very skilfully, with the official continuation.From 983 to 1018 C,

**D**and E are practically identical, and give a connected history of the Danish struggles under Ã†thelred II.From 1018 the relations of C,

**D**, E become too complicated to be expressed by any formula; sometimes all three agree together, sometimes all three are independent; in other places each pair in turn agree against the third.It may be noted that C is strongly anti-Godwinist, while E is equallypro-Godwinist,

**D**is a comparatively late MS., none of it probably much earlier, and some of it later, than 1100.In the case of entries in the earlier part of the chronicles, which are peculiar to

**D**, we cannot exclude the possibility that they may be late interpolations.Besides A, B, E, F, Ingram used C and

**D**for the first time.
