If these bacilli are injected into the tissue under the skin, or into the peritoneal or pleural cavity of guinea-pigs and rabbits, there will be produced after three, four, or more, weeks, a swell- ing of the lymphatic glands

If these bacilli are injected into the tissue under the skin, or into the peritoneal or pleural cavity of guinea-pigs and rabbits, there will be produced after three, four, or more, weeks, a swell- ing of the lymphatic glands near the seat of the inoculation, and these glands will subsequently caseate and ulcerate, just as.

The above picture is a representation of the microscopic appearance presented by a section of a portion of the kidney of a rabbit which died from the effects of Artificial Tuberculosis, (a) Blood-vessel filled with caseous matter, and in it numerous tubercle-bacilli.

After Klein. they would do, if they were affected with the disease in any other way. The spleen also is enlarged by the growth of numerous tubercles. The liver also is seen to be mottled by whitish points and streaks, which afterwards merge and become caseous. The peritoneum and bronchial glands are also attacked, and the lungs show isolated tubercles which are at first grey and transparent, and then become caseous in the centre. It has been suggested that if the germs of typhoid fever are inhaled, from drain-pipes or otherwise, the disturbance set up commences in the lungs, while if the source of mischief has entered the system by being swallowed, the first signs of the.
