Verf. resümiert wie folgt: ,,1. In both pelagic and demersal eggs 

 the final stage at the close of ovarian growth is characterised by the 

 i'i\trance into the ovum of a certain quantity of watery fluid of low 

 s|)ecific gravi ty. This fluid is secreted by the granulär cells of the 

 follicle and is probably essentially similar in composition to the free 

 fluid found in ripe ovaries producing pelagic eggs. 2. This fluid causes 

 the more or less complete fusion or Solution of the yolkspherules, and 

 hence the translucency or transparency of the vitellus; and it is asso- 

 ciated with the dissolution of the germinal vesicle and the rearrangement 

 of the chromatic substance concerned in fertilisation and heredity; 

 also with the escape of the egg from the follicle. 3. In pelagic eggs, 

 which float isolated in the sea, the quantity of fluid, that enters the 

 ovum is very large, distending it to three or four times its former 

 volume, and completely dissolving the yolk-spherules; and that such 

 eggs float by virtue of the large quantity of fluid of low specific gravity 

 absorbed. 4. That in one form at least (Lophius piscatoriiis), and 

 probablv' in. others, this change is preceded or accompanied by a
