Succinic acid also reappears in the urine. Not so, how- 
ever, with the benzoic acid; for this seems to become trans- 
formed within the organism into hippuric acid — according 
to the observations of Wohler, Boye, and Learning. 
The infusion of nut-galls is known to pass into the urine- 
for a black precipitate is found to be formed on the addition 
of ferruginious solution. After the administration of odine, 
the iodurets of potash and ammonia are discoverable. The 
alkaline carbonates also, the borates, silicates, and the 
chlorates may be detected by the addition of their respec- 
tive reagents. The same holds true of the yellow prussiate 
of potash ; the red prussiate is converted into yellow. The 
sulphuret of potassium is absorbed in part only, without 
alteration ; part becoming oxydised during the circulation, 
and converted into a sulphate. 
The vegetable salts, having potassa and soda for their 
bases, are transformed into carbonates ; for the urine is then 
found to be alkaline, and to effervesce on the addition of an 
acid. The same phenomenon is often observed when a 
person has been eating very freely of certain fruits, as apples 
cherries, strawberries and raspberries, which contain the 
malate or the citrate of potassa. This fact explains the 
utility of these fruits occasionally as a remedy in uric acid 
gravel.— Ibid, from Journal de Pharmacie.
