entitled "Two chapters in modern biology: I. Sexual 

 reproduction in watersilk (SpirogyraJ ; 2. The feeding habits 

 of Vampyrella lateritia.'' Dr. Lloyd described the development 

 of the sexual reproductive structures of Spirogyra longata, and 

 dealt particularly with the process of union of the sex cells and 

 the subsequent condensation to form the fertilized egg. The 

 account was based upon the researches which have recently been 

 carried on by the speaker. The illustrations were all made from 

 living material by the speaker personally, and included, in 

 addition to lantern slides, a motion picture showing the process 

 of union of the sex cells. 



A particularly interesting feature of the lecture lay in the 

 behavior of the above mentioned sex cells compared with that 

 of a curious non-cellular animal form known as Vampyrella 

 lateritia. This little animal feeds entirely upon the water silk, 

 and during its feeding it expands very greatly. During a brief 

 period following the feeding, the acquired bulk is rapidly lost 

 and the volume of the aniinal is restored to normal. It has been 

 found that the process here is precisely similar to that by w^hich 

 the united sex cells of the water silk lose their bulk. The feeding 

 habits of Vampyrella were shown in a motion picture in which 

 the whole behavior of the animal was seen in detail.
