very interesting, because only two or three other persons, including Pi'of. 

 Huxley, had seen and described them. He (Dr. Cobbold) had never seen 

 them himself. Of course the important question to decide was, what was 

 the significance of these singular formations ? What Dr. Whittell had 

 noticed was something totally distinct from the psorosperms exhibited at 

 the last meeting, and it would seem that they must be divided into two 

 groups — those which were of an ovoid form and those which were of an 

 Amoeboid character. Undoubtedly, in the case which had been mentioned 

 these structures differed entirely from any of the various organizations he 

 had himself described. He confessed that the facts recorded in the paper 

 of Dr. Whittell puzzled him very much, and threw him back again upon 

 the notion that the formations in questions were really the result of the 

 degeneration of an Hydatid Cyst. He was very glad indeed to have heard 

 this paper, aiid hoped that it would lead to many more observations being 

 made. The curious part of these studies was that every time they 

 examined these psorospertnial organisms they seemed to find something 

 different from what they had seen before. They must be content, there- 

 fore, to wait patiently for the results of many future observations before 

 any very definite conclusions could be established. 



The special thanks of the meeting were unanimously voted to Dr. 

 Whittell for his paper. 



Mr. A. D. Michael called attention to a specimen of OrnitJiohin avicu- 

 laria found parasitic upon a Jay ; it was shoAvii for the sake of exhibiting 

 the nervous and muscular systems and the brain and optic nerves. It was 

 mounted just as it was caught. 



Dr. Matthews enquired if any member could inform him of a method of
