ever other cyanuric ethers having a different constitution. Cyanate of 
methyl is prepared by the distillation of 2 parts of sulphomethylate of 
potash with 1 part of cyanate of potash. It is a light, colorless, very 
irritating and suffocating. Its formula is C2H30, CyO, and its most 
remarkable property is the facility with which it is transformed into 
cyanurate of methyl, a change whic aa place spontaneously when 
the ether is left to itself in a closed t his change sometimes 
takes place in the course of ibaa ie tence in a few minutes, 
and is accompanied in the last case by a sensible evolution of heat. 
The cyanurate of methyl is a solid ¢ crystalline body, fusing at 175°- 176° 
and boiling at 274°. It is very remarkable that its boiling point is 
higher than that of the cyanurate of ethyl which is 253°. With 
caustic, potash both these compounds of methyl _ carbonate of pot-

5. On some new Ethers.—Ciermont has studied in Wurtz’ labora- 
tory the action of iodid of ethyl upon — salts of silver, and has 
obtained several interesting ethers. Jodid of ethyl heated in a closed 
tube with pyrophosphate of silver yields iodid of silver and pyr rophos- 
phate of ethyl. The new ether is a viscid liquid, of a. burning taste 
and peculiar odor, soluble in water, alcohol and ether, and becoming 
promptly acid on exposure to moist air. Its formula is POs, 2CsHs0. 
lodid of ethyl acts in like manner upon tribasic phosphate ot silver, 
producing iodid of silver and the already known tribasic phosphate © 
ethyl, POs. 3CsHsO. Carbonic ether may be produced by the action 
of iodid of ethyl a carbonate of ape! It is too well known to 
be reproduced from gun cotton by means of the acetate of iro He
