URINE OF THE ELEPHANT. 



T is shown by the experiments of MM. John and Vogel, that the 



urine of the elephant does not contain berizoic, but hippuric acid. 

 M. Brandes has examined it and has obtained the same results, and 

 his experiments prove that it contains a notable quantity of hippuric 

 acid, and he procured it perfectly pure. 



He found in this urine : 



Hippuric acid combined with urea (hippurate of urea). 



An azotized extractive matter, soluble in water and in alcohol. 



Traces of a fatty matter and of a black resinous substance. 



Hippurate of potash. Carbonate of lime. 



Chloride of potassium. Phosphate of lime. 



Sulphate of potash. Carbonate of magnesia. 



Carbonate of ammonia. Mucus. 



The urine of the elephant does not then form an exception to the 

 constitution of herbivorous animals ; and M. Brandes concludes from 

 his experiments, that the urea is combined with acid, as demon- 

 strated by the researches of MM. Cap and O. Henry. The ele- 

 phant's urine contains a considerable quantity of earthy salts.

DELVAUXINE. 



Mr. Sandall has twice analysed a mineral named Delvauxine, 



which has the formula F 2 P + 24 H attached to it, and finds its 



composition to be very nearly as follows : 



Sesquioxide of iron 52'37 



Water 40'19 



Silica 3-95 



Phosphoric acid 2'62 



Lime "87 



100-00 

 The supposed composition denoted by the preceding formula is 



Sesquioxide of iron 12'82 



Water 69'23 



Phosphoric acid 17*95 



100-00 



It will be seen, by reference to vol. xiv., p. 474, of the Lond. and 

 Edinb. Phil. Mag., that Delvauxine, according to M. Dumont, is 

 composed of Peroxide of iron . . 30'30 



Water 41'30 



Silica 4-00 



Phosphoric acid . . 13'95 

 Carbonate of lime 10' 10 



99-65 

 If the discoverer of the mineral will repeat his analysis, he wil
