We can distinguish (I) digestive endoderm, in the stomach, often with special glandular elements; (2) circu-, latory endoderm, in the radial and ring canals; (3) supporting endoderm in the axes of the tentacles and in the endodermlamella; the latter is primitively a double layer of cells, produced by concrescence OC-- = w.?"
In using benzoyl chloride in this reaction the condensation is found to proceed better if a little ammonium chloride be added: 2C6H5 CNd-C6H5.0001 C6H5 C Cl OC C6H5 6 H 5 N C(C6H5):N The cyanidines behave as weak bases.
Also since dx has been stretched to +dy p&,(dx +dy) =po&odx or p&'(I +dy/dx) = (29) Substituting from (28) in (27) Y&a + P(2)U 2 (I + dy (3) 2 = p oc?oU 2, 0) and substituting from (29) in (30) Y&ao dx + pocZoU 2 + dx) = p owoU 2, (31) whence Yc = powoU2, or U2 = Y/ p, (32) where now p is the normal density of the rod.
II) whose centre is 0, AC its chord, and HK the tangent drawn at the middle point of the arc and bounded by OA, OC produced, then, according to Archimedes, AMC< HK, but > AC. In modern trigonometrical notation the propositions to be compared stand as follows: 2 tan 20 >2 sin 28 (Archimedes); tan 10+2 sin 3B>0> 3 sin B (Snell).
In length and 6 in height, which has been supposed to commemorate the great naval victory of Conon over the Lacedaemonians in 394 B.C. Among the minor antiquities obtained from the city itself, or the great necropolis to the east, perhaps the most interesting are the leaden KarrccB€o oc, or imprecationary tablets, found in the temple of Demeter, and copied in facsimile in the appendix to the second volume of Newton's work.
Also R=P. OC/OA + Q.
Thus ii AB, BC, CD represent the given loads, in the force-diagram, we construct the sides corresponding to OA, OB, OC, OD in the funicular; we then draw the closing line of the funicular polygon, and a parallel OE to it in the force diagram.
ACA, is C 2~r 2C. This is equivalent to a negative riitation 2C about OC, whence the theorem that FIG.
About OA, OB, OC, respectively, is to leave the body in its original position, provided the circuit ABC is left-handed as seen from 0.
Thus in the case of fig 36 it may be required to connect, the infinitesimal rotations f, i1, l about OA, OB, OC with the variations of the angular co-ordinates 0, ~, ~.
-- o, and draw OC parallel to the vector-sum.
BB each into two compon FIG A2 ents parallel and perpendicular toOC, we see that the former components have a single resultant in OC, of amount R~AA cos a+BB cos $, (2)
Axis of the fixed and OC that of the rolling cone, and J is the point of contact of the polhode and herpolhode, which are of course both circles.
If a be the semi-angle of the rolling cone, ~ the constant inclination of OC to OZ, and ~ the angular velocity with which the plane ZOC revolves about OZ, then, considering the velocity of a point in OC at unit distance from 0, we have wsina=d~~sinfi, (3)
At 0 be A, A, C, and if n be the constant angular velocity about the axis OC the FIG.
Again, the components of angular momentum about OC, OA are Cn,A sin 0~, and therefore the angular momentum (u, say) about OZ is pA sini 0 ~+Cn cosU.
83 OZ is supposed to be vertical, and OC is the axis of the solid drawn in the direction 0G.
36 we see that the angular velocities p, q, r of the moving lines, OA, OB, OC about their instantaneous positions are p=Osin4,sin0cos4,~,q=cos4,+sin0sin4,i~,~

It is certainly derived, through Rossiya, from Slavonic Rus or Ros (Byzantine `Pws or `Pc o-oc), a name first given to the Scandinavians who founded a principality on the Dnieper in the 9th century; and afterwards extended to the collection of Russian states of which this principality formed the nucleus.

Vary between Os (or 6) and In uncial writing OC Os) might easily be miswritten or altered to 6C (e€Os) or vice versa.
Induction (E7rayo.y17) and syllogism (ovXXcytcr oc), the general forms of inference, do not occur in the Rhetoric to Alexander.
This monarch had always Oc- been a thorn in the side of the papacy.
If all the water be frozen, we have the vapour pressure curve of ice OB; while, if the pressure be raised, so that all the vapour vanishes, we get the curve OC of equilibrium between the pressure and the freezing point of water.

It crystallizes (from water) in glistening leaflets which melt at 130° C. and boil at 288° C. Its silver salt behaves as if it were the salt of an imido benzoic acid, since it yields benzimido ethyl ether C 6 H 5 C(:NH) OC 2 H 5 with ethyl iodide (J.

36, if OA, OB, OC be three mutually perpendicular lines in the solid, we may denote by O the angle which OC makes with a fixed direction OZ, by ~ the azimuth of the plane ZOC measured from some fixed plane through OZ, and by f~ the inclination of the plane COA to the plane ZOC In fig.
