rachitis, whilst other pigs of the same litter, who, besides 
potatoes, received powder of lye, meat, and phosphates, 
had a normally developed skeleton. Among these latter 
were some differences nevertheless. Those fed with potassic 
phosphate had bones more porous and less dense than those 
who received, besides potassic phosphate, phosphate and 
carbonate of lime (Amth. Bericht d. 50 verslg. Deutsch 
Naturf, &c.). 
On the Influence of the Fumes of Metallic Works on the 
Production of Tuberculosis and Rachitis in Cattle. By 
Haubner. — In the neighbourhood of the metal foundries 
of Freiberg cattle are affected with diseases of the osseous 
tissue—rachitis in growing stock, oteoporosis in older ani¬ 
mals, especially in milch cows, from whom large quantities 
of lime and phosphoric acid pass in the milk. The herbage 
here is remarkable for an abnormal richness in acids, whilst 
in the ash acid sulphates replace basic carbonates. Besides 
sulphuric acid, the fumes of the foundries contain arsenic, 
lead, and zinc. The form of tuberculosis observed in the 
cattle is not the ordinary, it is confined to the lungs, and 
the author attributes it to the dust of arsenic, zinc, and lead, 
which, spread over the herbage, during feeding penetrates the 
respiratory passages. The diseases of hone result from in¬ 
sufficient consumption of lime, and from excessive loss of 
phosphate of lime resulting from an acid diet. In addition 
all the organism is acidified, the contents of the first three 
stomachs and of the intestine, the marrow of bones, the 
saliva, and the urine have an acid reaction; besides, the 
urine contains a very large amount of phosphate of lime. 
Since these facts have been proved measures have been 
taken to prevent dispersion of sulphuric acid in the air, and 
the above-mentioned disorders seldom claim victims ( Cen - 
tralblatt fur Agriculturchemie, vi, 9). 
On Pneumonia in the Bovine Species, by Dr. Anacker.— 
The question whether cattle suffer from a non-contagious 
sporadic form of pneumonia having been recently raised, 
Anacker considers that after the number of- cases cited in 
support of this possibility there can be no question of the 
matter. He cites the latest instance observed by him tend¬ 
ing to support the observations which he has already col¬ 
lected upon this subject. Last spring he was officially 
informed of the opening of a cow slaughtered in the abattoir 
in which had been noted the characteristic marbled appear¬ 
ance of the lung of pleuro-pneumonic zymotica or peripneu¬ 
monia. He visited the establishment of the seller of this 
beast, who had had her in his possession for more than a year,
