Mr. Brothers exhibited the Floscularia ornata, and a 

 fine group of Lacinularia socialis. 



Mr. MosLEY exhibited a specimen of Amoeba^ and 

 described the peculiarity of its motion. He had observed 

 one of them rise in a straight line four-fifths of its entire 

 length, its internal particles appearing to force outwards a 

 transparent or invisible integument ; the point then fell over, 

 forming an arch, after which it subsided into the common 

 three or four-lobed form. In many specimens no vacuole 

 was observed ; in others, an apparent air or water space was 

 noticed. A portion of the one under examination appeared 

 to be blown outwards like a bladder, in w^hich appeared a 

 small animalcule making desperate efforts to escape. The 

 best illumination for observing the internal motion, he con- 

 siders to be Wenham's parabola and Lieberkiihn, with a 

 4- 10th objective.
