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.?"

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.

These esters on hydrolysis yield the free acids, which readily decompose, with loss of carbon dioxide and formation of an aldehyde, R /Crri /Crri Oc< +ï¿½Cl ï¿½ CH ï¿½ [[Cooc H - O I ?Ch Cooc H 0c Chï¿½Cooh - Co +Chrr I Cho]].
CH(OC 2 H 5) 2j is produced.
Thiele, Ann., 1898, 302, p. 299): HN:CC NH NH2 OC C 6 H 5 NH N + -> HN:CC C C6 H 5 NH 2 OC C6H5 N = C/-C6H5 Wolff has obtained a chloro-derivative by the action of potassium cyanide on diazoacetophenone and subsequent treatment with acid.
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.
Glyceric aldehyde, CH 2 OH CH(OH) CHO, was obtained pure by Wohlon oxidizing acrolein acetal, CH 2 CH(OC 2 H 5) 21 and hydrolysing.
Between F and A A Virtual Virtual, erect, diminished Erect, same size CO Between oc and A A a superficial account of the traffic in indulgences, and a rough and ready assumption, which even Kostlin makes, that the darkness was greatest just before the dawn.
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.
Y, hence DC is the half of OC, proving the curve to be a parabola.
B, lateral view, showing viscera: oc, eye-spots; n, nephridia; e, ciliated toes; other letters as above.
Other words, by a non-Euclidean construction he trisected the angle AOC, for it is readily seen that, since FD' = FO = OC, the angle FOB = 2 AOC. 6 This couplet of constructions is as important from the calculator's point of view as it is interesting geometrically.
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).
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.
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.
It reacts with sodium ethylate to form ortho-formic ester, CH(OC 2 H 5) 3, and when heated with aqueous ammonia for some hours at 200-220° C. gives carbon monoxide and ammonium formate, 2CHC1 3 + 7N11 3 -13H 2 0= NH 4 HCO 2 + C0+6NH4C1 (G.
R C02C2H5 - > R C - OC 2 H 5 - j R C R' - jR' - C OH.
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~,~
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.
37) can turn about a diameter OC of a ring which is itself free to turn about, a diametral axis OX at right angles to the former; this axis is carried by a second ring which is free to turn about a fixed diameter OZ, which is at right angles to OX.
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)
