OSTEOMALACIA AND RACHITIS. 
By. S. Roloff. 
By long privation of calcareous p v inciples, Boloff has suc¬ 
ceeded in producing in young dogs, not only an arrest in the 
general nutrition, and in the increase of weight, but also the 
clinical phenomena and anatomical lesions of rachitis. Three 
dogs, five-and-a-half weeks old, of the same litter, and in robust 
condition, received each day 200 gramms of horse-meat, 60 of 
starch, 30 of suo;ar and 10 of oil. The lirst had each dav in 
addition 10 gramms of phosphate of soda, and a like amount of 
phosphate of magnesia, in 200 grams of water; the second, in 
addition to this saline solution, had 10 gramms of phosphate of 
lime; the third had neither lime nor phosphates. 
The second increased much more rapidly in weight than the 
others. The autopsy exhibited in the first and the third, the 
lesions of rachitis. A counter-experience is foutided by the treat¬ 
ment of a rachitic young dog, which recovered in three months 
by the use of phosphate of lime. 
Experiments made on goats and sheep could not be followed 
to the end, because those animals refused the food given, and 
starved themselves rather than take it. The author reports only 
two cases of lesions of osteo-malaria, in a goat and a ewe, which 
had lost much in calcareous principles by excessive lactation. 
TREATMENT OF FOOT AND MOUTH DISEASE BY SALICYLIC ACID. 
Salicylic acid has recently been employed by the Duke of 
Brunswick in the treatment of this disease, with surprising re¬ 
sults, a cure being obtained within a few days. A solution was 
made by adding about three tablespoonsful of the acid to one
