consisted of phosphat of lime*. Dr Pearson found a 
calculus taken from the bladder of a dog composed of 
phosphat of lime, phosphat of ammonia, and an animal 
matter. He found the urinary calculus of a rabbit, of 
the specific gravity 2, composed of carbonat of lime and 
some animal matter t.

THUS I have given an account of all those secretions 
which have been attentively examined by chemists. The 
remainder have been hitherto neglected ; partly owing 
to the difficulty of procuring them, and partly on ac 
count of the multiplicity of other objects which occu 
pied the attention of chemical philosophers. It re 
mains for us now to examine by what processes these 
different secretions are formed, how the constant waste 
of living bodies is repaired, and how the organs them 
selves are nourished and preserved. This shall form 
the subject of the following Chapter.
