albumen and gelatine. 
“ I have for obvious reasons omitted the benzoic acid. 
“ The principal and only essential difference between the 
urine of the camel, and that of the cow, is that the former 
contains uric acid. They both appear to be destitute of soda. 
“ It will also appear that in the present instance the latter 
contains a larger proportion of saline matter, but this can only 
be regarded as a casualty, when we consider the variation, to 
which the relative proportion of water to the salts of urine is 
liable, according to the circumstances under which the secre- 
tion takes place." 
From Mr. Brande’s experiments on the urine of the camel, 
it appears that (exclusive of water) the principal ingredients 
are muriat of potash, and urea ; and as ammonia is present only 
in a very small proportion, which is even less than in the urine 
of the cow, we may conclude that the various accounts, which 
state the urine of the camel to have much contributed to the
