Conjugation in Trypanosoma of Rat. * — H. Stassano briefly de- 

 scribes wbat he interprets as conjugation-processes in the Trypanosoma 

 of the rat (7-10 days after inoculation). Individuals were seen united, 

 the anterior end of the one to the posterior end of the other, and tho 

 author made some observations on the behaviour of the nuclei. But 

 more detailed descriptions and figures seem desirable. 



Protozoon Parasite in Plaice. | — James Johnstone describes certain 

 remarkable appearances noticed in the gut of two specimens of Pleuro- 

 nectes platessa, apparently due to the presence of a Sporozoon. In both 

 cases the intestine, from the pylorus to near the anus, was thickened and 

 granulated, so that its wall resembled the ripe ovary. Sections showed 

 that the mucosa had disappeared, and the sub-mucosa was crowded with 

 little spherical bodies consisting of capsules filled with minute spore- 

 like bodies.
