The President called attention to some portions of liver of Ostend rabbit 

 containing large quantities of Cysticercus pisiformis, which had been placed 

 on the table for distribution, and remarked that the specimens would no 

 doubt be interesting, as the subject had excited much attention of late, 

 attempts having been made to show that many of these parasites were 

 merely polymorphic forms of other species. This he thought could not be 

 maintained. The specimens on the table were common bladder worms, 

 ■which became transferred into the Taenia serrata of the dog. 



The President exhibited a large hand cut section of bone, showing the 

 manner in which new bone was formed round the shaft of the femur. The 

 cells of the new bone completely surrounded and enclosed the old, which 

 had become destroyed by Necrosis. The specimen showed how difficult it 

 would be to remove the old bone without permanent injury to the limb. 



Mr. Ingpen exhibited and described Mr. Wenham's new immersion 

 illuminator, illustrating his remarks by drawings on the black board.
