uncoordinated movements and blindness. These symptoms, as well as 

 those of the heart (rapid palpitation) prove that S. columbaczense injects 

 some toxic substance which reaches the nervous system and paral^'ses the 

 nervous centres of the medulla oblongata ; during this process the modifi- 

 cation in the circulation causes tumours on the soft part of the larynx, 

 which hinders respiration. 



The Author suggests that further extensive experiments be underta- 

 ken with the. blood of diseased animals, and the pathological changes of 

 the nervous tissue, if any, be studied. 



The meat of slaughtered animals is quite harmless to man. To facili- 

 tate control, herdsmen should, before the Simuliimi appear, be made 

 acquainted with various protective means and recommended to destroy 

 severely attacked animals before death occurs and to bleed them thoroughly.

Work carried out at the Institute of Pathology and Clinical Medicine 

 of the Royal University of Bologna. 



Several writers have shown that a large number of trypanosomes are 

 able to pass through the different mucous membranes, andNATTAX Larrxer 

 has already taken in hand the solution of the problem of trypanosomes pass- 

 ing into milk. The result was affirmative as regards Tr. schizotripanum 

 Cruzy, and almost alwaj^s negative for Tr. equiperdimi. The writer next 

 describes his experiments with the tr3-panosomes Brucei, Evansi, rodesiense 

 and gamhiense. 



The virus was injected into the veins of bitches which had just littered. 

 It was desired to find : i) whether the young when allowed to suck were 

 infected ; 2) whether the presence of trypanosomes could be detected by 

 di ect examination of milk ; 3) whether the milk when inoculated into the 

 peritoneum was able to infect rats or mice. 



From the results it is concluded that : 



i) The passage of the trypanosomes Brucei, rodesiense and gamhiense 

 into milk is possible. 



2) The infection with the virus of Brucei and gambiense can be trans- 

 mitted by suckling.

The results obtained in the investigations and tests carried out at the 

 " Stazione sperimentale per le malattie infettive " of Milan, confirm those 

 which had previously been obtained by Messrs. Cosco and Aauzzi (i) and 

 lead to the following conclusions : 



i) The virus is preserved indefinitely by means of its successive pass- 

 age through animals susceptible to the disease, when blood products (se-
