Micro-Organisms and Disease.* — S. J. Hickson gives a lucid account 

 of some of the recent advances in the study of micro-organisms associated 

 with disease. He refers to ankylomiasis, the miner's disease due to the 

 Nematode Ankylostoma duodenale, whose larvae penetrate the skin, enter 

 the veins of the skin, pass to the lungs, and thence to the intestine. He 

 goes on to Monocystis himbrici, Coccidium oviforme, 0. schubergi, and 

 thence to the Hannosporidia and the Trypanosomes. 



Trypanosoma duttoni.f — Thiroux discusses this species, found in 

 the blood of mice. It belongs to the type lewisi, but T. lewisi from 

 the rat cannot be inoculated into the mouse, nor T. duttoni into the rat. 

 Other Trypanosomes from rodents, e.g. from squirrel and rabbit and 

 hamster, may be referred to this same type lewisi.
