served besides, that no disengagment of carbonate of ammonia would 

 occur, for the alkali developed was immediately converted into a 

 fixed salt. 



M. Boussingault observes that the above-described process appears 

 to be susceptible of being advantageously employed in situations in 

 ■which a large quantity of urine may be collected, as in the work- 

 shops, hospitals, prisons, &c. of towns, because an efficacious manure 

 would be obtained which is particularly easy of transport. The 

 diminution of the bad smell ought also to be considered ; for it is 

 evident that a magnesian salt acts under these circumstances as a 

 disinfectant. In establishments situate in agricultural districts, the 

 process would possess but little utility, because the urine could be 

 there employed immediately and without any preparation ; and the 

 only advantage which could result from the use of a magnesian salt 

 under these circumstances, would be the prevention of the loss of 

 ammonia, a loss which the author thinks has been much exaggerated.

CHEMICAL RESEARCHES ON THE YOLK OF EGGS. 



M. Goble}'^ states that the fresh researches which he has made on 

 this subject were undertaken with a two-fold object, one of which 

 was to consider certain points which he had scarcely touched upon 

 in his first communication, another object was to determine how far 

 the objections of M. Sacc against his conclusions were v/ell-founded ; 

 with these views the author modified several of his analytical pro- 

 cesses, so as to be quite certain that he would avoid the causes of the 

 errors which had been supposed to be discovered. 



M. Gobley concludes from his recent experiments, — 



1st. That the fatty matter of the jmlk of egg is formed, as had 

 previously been stated, of two distinct parts ; one a fixed oil, tlie oil 

 of egg, and of a soft, not fusible substance, viscous matter. 



2nd. Tiiat the phosphorus does not occur in the oil, but in the vis- 

 cous matter. 



3rd. That oleic, margaric, phosphoglyceric, lactic acids, and the 

 extract of meat are not products of oxidizement. 



4th. That the viscous matter is not, as the author imagined, a 

 coml)ination of oleic, margaric and phosphoglyceric acids with am- 

 monia, but constitutes a body of a comj)lex nature from whicli two 

 different substances have been separated, to which tlie author has 

 provisionally given the names of phosphorized mutter and cerebric 

 matter. 



5th. That the i)hosphorized matter which forms in the future animal 

 the sul)stance described by M. Fremy as oleophosphoric acid, yields 

 oleic, margaric and j)hosphoglyceric acids with the greatest facility, 

 as products of decomposition in the j)resence of acids and mineral al- 

 kalies under the influence of water or alcohol, and without tlie inter- 

 vention of the oxygen of the air. 



Cth. That the cerel)ric matter is analogous, if not identical with tlie 

 substance which Vauquelin, MM, Coucrl)e and Frcmy have succes-
