TUBERCULIN, ETC., IN THE ERADICATION OF TUBERCULOSIS. 161 
a bronchial lymphatic gland enlarged to the size of a duck’s 
egg, and containing glairy liquid pus. There was an absence 
of the cheesy matter usually associated with tuberculosis and 
the walls of the pus cavity were thinner than we usually see in 
lymphatic glands undergoing tubercular suppuration. 
It here devolves to sav a few words on the arrangement of 
the stable where these animals were kept and on the steps taken 
to cleanse and disinfect it. While all the animals were kept un¬ 
der one roof, yet the building can best be described as consist¬ 
ing of two parts. That part in which the milch cows were kept 
measures 30 X 6o feet and the ceiling is io }4 feet high. The 
floor is of brick set on edge in cement. The windows, twelve 
in number, face east and west; they measure 3 x 2 feet and 
are placed within two feet of the ceiling. There are two ven¬ 
tilators, each three feet square. The ceiling is of narrow pine 
boards planed and varnished and the lining of the walls is of 
the same material. The stable is arranged for twenty-six cows, 
the animals standing in two rows facing each other with walks 
between them and behind them about five feet wide. 
The young stock were for the most part kept in box-stalls, 
arranged in two rows and communicating with the cow stable 
by a five-foot passage way. While under the same roof they 
were, with the exception of the passage way, isolated from the 
part in which the cows were kept, and, although reared on 
their milk, never came in direct contact with them. 
Cleansing a 7 td Disinfection. 
All the remaining stock having been removed, cleansing 
and disinfection was proceeded with as follows : 
(1) Dry brushing of the whole interior of the building. 
(2) Scrubbing the entire interior with soap and hot water 
ad lihituin. 
(3) Saturation of the entire interior with an antiseptic 
wash made up in strength and of ingredients as follows: 
Bichloride of mercury, one ounce ; glacial carbolic acid, twelve 
ounces ; hot water (scalding), twelve gallons. This was applied 
copiously and forcibly with large garden syringes.
