Abstract
The difference of the blood pictures between controls and rabbits with ammonia injection which were both inoculated with 3 mgrms. of tubercle bacilli (human type) intraocularly, was as follows:-
1. Total white cell count. Control animals showed a remarkable leucocytosis or a leucopenia. Rabbits with a leucocytosis survived longer than those with a leucopenia. Contrarily the rabbits with ammonia-injection showed a leucopenia and died in a few weeks.
2. Lymphatic and myeloid cells. In the case of controls a lymphopenia and a myelocytosis were seen; these changes were more remarkable at the end of this experiment. On the contrary, the rabbits with ammonia-injection showed a shift to the right and the shift was obviously of a degenerative nature.
3. Monocytes, eosinophiles and basophiles. Control animals showed a remarkable monocytosis, but in the case of animals with ammonia injection only a slight monocytosis occurred. Eosinophiles decreased in both cases and disappeared entirely before the death. Basophiles showed a slight increase in both cases.
