236 Histology .of Sleeping Sickness and Trypanosomiasis, etc. 



(8) The brain of a case of Trypanosomiasis did not show small celled 

 infiltration. 



(9) Animals infected with Trypanosoma Gambiense show sometimes 

 changes in the nervous system, localised in the grey matter, haemorrhages, 

 lymphocytes, and a few leucocytes in the peri- vascular space : hsemo-lymph 

 glands in large numbers, and sometimes necrosis of the spleen and degenera- 

 tion of the bone marrow. 



(10) Animals infected with Trypanosoma dimorphum exhibit similar changes 

 in the nervous system and organs. A far greater deposit of pigment in the 

 lymph glands and in older cases in the spleen is present.
