VACCINATION OF SHEEP. 
Notwithstanding the frequently reported inefficacy of vac- 
cination in this country and elsewhere, as a preventive of 
variola in the sheep, Dr. Pipin states, as the result of his ex- 
periments and observations, that this operation is of little 
moment, and affords the animals w r hich have been sucessfully 
submitted to it an immunity from smallpox. Consequently, 
he considers that vaccination may be advantageously sub- 
stituted for inoculation . — Wochenschrift fur ThierheilJcunde,

MYCOSIS OF THE LUNGS IN A HORSE. 
In the forty-ninth volume of c Virchow’s Archives/ Dr. 
Bollinger describes a case in which vegetable parasites of low 
organization acted as. a morbid agent in the production of 
disease. At the autopsy of an old and badly fed horse, made 
at the Veterinary Institute of Vienna, there w-as noted, in 
addition to the lesions of acute pericarditis and hydrothorax, 
the existence in each lung of from five to seven nodosities, 
varying in size from the magnitude of a hazel-nut to that of 
a w 7 alnut. These nodosities were nearly all sub-pleural, and 
occupied the posterior and superior portion of each lung; 
they were hard to the touch, of a whitish-grey colour, and 
sent prolongations into the adjacent tissue; at first sight 
they looked like simple fibroma. Offering some resistance 
to the scalpel, these nodosities presented on the cut surfaces 
three or four spongy patches of the volume of a hemp-seed 
to that of a pea, and resembling in no respect any patholo- 
gical production heretofore described. They were isolated 
from the healthy pulmonary structure by a loose layer of 
conjunctival tissue, or, though rarely, by a thin capsule of 
the same material ; these small spongy centres not only com- 
municated with each other, but also with one or more of the 
fine bronchi, and in one of the nodosities they were replaced 
by a bronchectasy the size of a pea, w 7 ith unequal sinuous 
walls, and communicating with several of these centres. In 
passing the knife lightly over one of the spongy places a 
whitish puriform fluid was removed, in which the eye could
