they are ejected, according to the general statement, at one 

 of the so-caUed poles ; but Mr. Brown stated that he had 

 observed this take place also at other points. The young 

 plants are ejected sometimes to about l-20th of an inch, and 

 soon begin to move about. At first the gonidia are closely 

 packed, and are consequently hexagonal in shape; when 

 older they are more remote, but are still connected by minute 

 strings of protoplasm. In the other mode of reproduction 

 (the sexual) some of the gonidia become much enlarged, 

 and a dark green mass appears in their centre, called the 

 oogonium ; another form also appears, called the antheridium, 

 contaming little cells closely packed, with smaU filaments 

 attached. From these, little bodies escape, sometimes even 

 penetrating the outer wall of the Volvox ; when these come in 

 contact with the oogonium they pierce it, producmg fertili- 

 sation. During this process of reproduction the Volvox has 

 an orange colour. 



Mr. Brown gave some description of the Fresh-water Me- 

 dusa {Ldmnocodium Sowerbii), recently discovered by Mr. 

 Sowerby, and described by Prof. Eay Lancaster, first foimd
