H HN CEH?Chch C(Ch3)N.Cs The ketonic esters under like treatment yield oxypyrimidines, whilst if cyanacetic ester be employed then amino-oxypyrimidines are obtained.
If the tangent at P meets the asymptotes in R, R', then CR.CR' = CS 2.
Besides the revolutionists and republicans who promoted con~ spiracy and insurrection whenever possible, and the moderates or Neo-Guelphs, as Giobertis followers were called, we must mention the Italian exiles who were learning the art of war in foreign countriesin Spain, in~ Greece, in aas Poland, in South Americaand those other exiles who, ~rn CX CS Paris or London, eked out a bare subsistence by teaching Italian or by their pen, and laid the foundations of that love of Italy which, especially in England, eventually brought the weight of diplomacy into the scales for Italian freedom.

CARBON BISULPHIDE, CS 2, a chemical product first discovered in 1796 by W.

Hofmann), CS 2 +2NH 3 -->NH 2.
Carbon bisulphide combines with primary amines to form alkyl dithiocarbamates, which when heated lose sulphuretted hydrogen and leave a residue of a dialkyl thio-urea, CS 2 +2R NH 2 - R NH CSS NH 3 RCS(NHR)2+H2S; or if the aqueous solution of the dithiocarbamate be boiled with mercuric chloride or silver nitrate solution, a mustard oil (q.v.) is formed, R.NH CSS NH3R+HgC12-Hg(R NH CSS)2->2RNCS-}-HgS+H2S.
Carbon monosulphide, CS, is formed when a silent electric discharge is passed through a mixture of carbon bisulphide vapour and hydrogen or carbon monoxide (S.
Phosphorus pentasulphide at 140 - I 50° C. converts it into xanthion by transformation of > CO to > CS (R.
The metals may be arranged in a series according to their power of displacing one another in salt solutions, thus Cs, Rb, K, Na, Mg, Al, Mn, Zn, Cd, Tl, Fe, Co, Ni, Sn, Pb, (H), Sb, Bi, As, Cu, Hg, Ag, Pd, Pt, Au.

When heated with CS 2 to 1 00° C. under pressure, it forms liquid nitrogen sulphide, N 2 S 5, a mobile red liquid which solidifies to an iodine-like mass of crystals which melt at Io-I I° C. Water, alkalis and acids decompose it into sulphur and ammonia (W.

Insecticides, of which the bisulphide of carbon (CS 2) and the sulpho-carbonate of potassium (KS CS2) remain in use, were injected into the earth to kill the phylloxera on the roots of the vine.
CAESIUM (symbol Cs, atomic weight 132.9), one of the alkali metals.
Caesium hydroxide, Cs(OH) 2, obtained by the decomposition of the sulphate with baryta water,is a greyish-white deliquescent solid,which melts at a red heat and absorbs carbon dioxide rapidly.
Caesium sulphate, Cs 2 SO 4, may be prepared by dissolving the hydroxide or carbonate in sulphuric acid.
