A double section was made in the radii of two dogs, and a 
piece of bone taken out of each ; the wounds were closed by 
sutures. After the operation they were kept for twenty-five 
days. One of these clogs received nothing but caseine and 
distilled water; the other received the same, with the addi- 
tion of salt. On examination after the twenty-five days, it 
was found that the piece of bone extracted from the dog that 
had taken the salt was completely restored, while that in the 
dog which had not received any salt showed no trace of the 
formation of bone. 
The two radii are preserved in the Laboratory of the 
Academy of Medicine in St. Petersburgh. 
[Does not this indicate the benefit of common salt in all 
fractures, and in cases where the formation of bone might be 
deemed an advantage? — Translator.] 
NOURRITURE DES CHEVAUX DE TRAVAIL. 
This is the title of a little work by J. H. Magne, Director 
of the Imperial Veterinary School at Alfort, on the food of 
working horses. The author observes, that to determine the 
equivalent of nutritive matter in vegetable aliments, those 
principles must be studied, which play an important part in 
nutrition, and vary in quantity in the different aliments; 
viz. the nitrogenous (azotes), also designated the albuminoid , 
fibrine, gluten, caseine, legumine, &c. 
The fatty matter (corps gras), oils, essences, resin, &c. The 
neutral solubles, designated also the saccharoids , sugar, glucose, 
feculen, gumen, &c. The author does not deem it necessary 
to make a particular study of the insoluble principle of vege- 
tables, the ligneous and cellulous, nor of the mineral , though 
they are necessary, the first to fill out (lester les animaux) 
and the others to constitute the organs. The first are sup- 
plied by the fibrinous aliments. When the ration contains 
even but a small quantity of hay and straw, it will suffice ; as 
to the mineral matter their value is principally in the phos- 
phates which they contain, and it is in the grain principally 
they are found in the greatest abundance. The plastics, the 
same as the nitrogenous elements, are in proportion to the 
latter; thus a ration rich in albuminoids will also contain the 
most mineral principles. The nitrogenous or albumenoids are 
nearly composed as follows : 
Carbon . 54 1 Oxygen . . 24 
Hydrogen . 7 | Nitrogen . .16
