phosis of the Nauplius into a pupa and subsequently-into an ani- 
mal of a sessile and immobile habit of life; second, it is due to 
parasitism (Symbiosis). An approximate stability of the present 
form of Sacculina is maintained by the important law of heredity, 
very slow changes in color, form, etc., will, however, make their 
appearance by changes of climate and immediate surroundings, z. €., 
the host. In concluding, let me quote from E. Haeckel: “ The series 
of forms which the individual organism passes from the egg up to 
the development of the adult form is but a brief and rapid reca- 
pitulation of the series of forms, which all the ancestors of this 
organism have passed since the beginning of the organic history 
of the earth down to the present day. This repetition or recapit- 
ulation is conditioned through the laws of heredity and modified 
through the laws of adaptation. The historical record, preserved 
in the developmental history of the individual, is rendered grad- 
ually obliterate, the development gradually taking a more and 
more direct course from the egg up to the adult, and it is also 
often falsified through the struggle for existence which the free- 
living young are subject to. The falsification of the ontogenetic 
product is conditioned through the law of the modified or falsified 
heredity.”
