INFLUENCE OF COMMON SALT (CHLORIDE OF SODIUM) ON 
THE ABSORPTION, BY THE ANIMAL ECONOMY, OF THE 
TRIBASIC PHOSPHATE OF LIME. 
Bj MM. Zerbeline and Dorogoef, of St. Petersburgli. 
To resolve the question of the influence of common salt 
on the absorption of phosphate of lime in the animal 
economy, it was necessary to determine at first the quantity 
eliminated by the rectum and urinary organs under the in- 
fluence of the salt, and also in the case of the total absence 
of it in the food. 
Dogs were taken for the subjects of these experiments. They 
were fed exclusively on caseine, which contained tribasic phos- 
phate of lime, and which, beyond this salt and the water, con- 
tained no trace of chloride or other soluble substances belonging 
to milk. Every day, at the same hour, the dog received a 
certain amount of caseine, and through a tube a quantity of 
distilled water, measured and of even temperature, was in- 
troduced into the stomach. The quantity of distilled water 
was varied in proportion to the quantity of water contained 
in caseine; in this way the dog received every day an equal 
quantity of caseine and water. All these experiments gave 
the same results. 
The method of the experimentation was as follows : — For 
the first seven days the dog received the caseine and the dis- 
tilled water, and no salt; the seven following days the dog 
received the same quantity of caseine and distilled water, 
plus 0*200 gr. per diem of common salt. In the first seven 
days the dog ate 700 gr. of caseine containing 8*608 gr. of 
phosphate of lime ; in the last seven days the dog also ate 
700 gr. of caseine, which contained 7‘232 gr. of phosphate 
of lime. 
During the first seven days there was eliminated per 
rectum ll*556 gr. of phosphate of lime, and by the urine 
0T14 gr. In the last seven days per rectum 6 873 gr., and 
by the urine 0*140 gr. Consequent on the absence of salt 
in the aliments, there was eliminated per rectum 2*888 gr. 
more of phosphate of lime than had been introduced into the 
stomach, and per rectum and urinary organs together 3*002 
more than was introduced into the stomach; on the con- 
trary, under the influence of salt, 0*359 gr. less were elimi- 
nated per rectum, and by the urinary organs and rectum 
together 0*219 gr. less than had been introduced into the 
stomach.
