During my first year of service at the LourenQO Marques 

 Bacteriological Laboratory, I have been able to record the 

 following Entozoa : — 



Entauioeha histolytica, Giardia {La)ublia) iutestinalis, Balait- 

 tidium coli. Trichomonas intcstinalis, Blastocystis honiinis. 

 TricJiuris fric]tiura {Trichocephalus dispar), Ascaris lumbricoides, 

 O.xyuris vennicularis, Ancylostoma duodeiiale, Strongyloidea 

 stercoralis, SrhistosoDia tnansoii, Schistosojua haematobium. 

 Taenia saginafa, and Hynienolepis nana. 



I often found ova which, from the number of membranes, 

 approached those of the Taeniae, but from the frill of the external 

 membrane somewhat resembled those of Ascaris. Whenever I 

 found ova which I was unable to identify, I asked for the total 

 dejections of the patients, passed after the application of a 

 vermifuge, in order to determine therefrom the corresponding 

 worm. Up to the present, I have not been able to obtain them' 

 under such conditions. As they frequently appear, I hope to 

 have the opportunity of completing this investigation. 



I have found dejections with only one species of the above- 

 nientioned parasites ; but in the majority of cases I have found 

 in the dejections of the same patient several parasites associated 

 in almost all possible combinations, as may be seen from the 

 followinof table: —
