Facts and Observations. 
THE ERENCH INTERNATIONAL EXHIBITION OE BREEDING 
STOCK AND AGRICULTURAL IMPLEMENTS. 
The government of France has decided that the Universal 
Agricultural Exhibition, which was to have been opened on 
the 1st of June next, at Paris, shall not take place this year; 
as many remonstrances have been addressed to the Minister 
of Agriculture, Commerce, and Public Works, with reference 
to the very short interval which would separate it from the 
meeting of 1856. 
DECOMPOSITION OE URIC ACID IN THE ANIMAL 
ORGANISM. 
Dr. Neubauer finds, from experiments with rabbits, one 
fed upon bread, the other upon carrots, that, under normal 
conditions, uric acid is entirely converted into carbonic acid 
and urea; and that oxalic acid may be formed w r hen the 
process of oxidation is restricted, as is the case during sleep, 
and in pathological conditions.— Pharmaceutical Journal . 
NEW METHOD OE REMOVING TUMOURS. 
Professor Simpson has lately removed some tumours, 
fatty, cancerous, &c., by a novel operation in surgery. It 
consists of introducing in the morbid mass a slender hollow 
acupuncture-needle, and injecting through it a few drops of 
solution of sulphate or chloride of zinc, iron, creosote, &c. The 
fluid thus introduced into, around, or beneath the morbid 
tumour, destroys its vitality, and the tumour itself is subse- 
quently thrown off by the process of spontaneous enucleation. 
The needle is thus substituted for the knife, and the operation is 
quite bloodless. Some ingredients, w r hen thus applied directly 
to the internal structure of tumours, may destroy their specific 
without destroying their general vitality ; and others lead 
more directly to absorption, by being brought in contact w ith 
the deposits that require to be absorbed . — Edinburgh Medical 
Journal .
