of accidental death was returned, but the whole of the jury 
expressed their decided opinion that in such cases all horses

EFFECTS OF MEDICINES ON THE URINE. 
The effect of different medicinal substances on the urine, ac- 
cording to Berzelius, is very striking, and occasionally very 
rapid. By calcining the sediment of the urine from patients 
who have used mercurial ointment, we may obtain globules 
of mercury. Nitre, the yellow prussiate of potash, and 
many metallic salts, especially those of iron, are easily and 
speedily detected in the urine. After iron has been em- 
ployed for any length of time, the urine acquires a feeble 
bluish and greenish tinge, owing, according to Berzelius, to 
the union of the iron with the ferrocyanic acid, which is 
generated by the decomposition of animal matters within 
the body. Soon after taking tartaric or oxalic acids, the 
urine often deposits as it cools, oxalate or tartrate of lime, 
which deposit is increased by the addition of the chloruret of 
lime to the fluid. The malic, citric, tartaric, and succinic 
acids render the urine more or less decidedly acid. The 
benzoic acid is converted into the hippuric. The infusion 
of galls taken internally causes the urine to throw down a 
black precipitate with the salts of iron. The vegetable salts 
having potass 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 is some- 
times observed after eating freely of fruit, the urine contain- 
ing the malate or citrate of potash, which explains the utility 
of fruit in the uric acid deposit . — Journal de Pharmacie .
