The tenth chapter (pp. 177-228) of the first part of this work is 
devoted to the consideration of the development of the Mammalia. The 
Rabbit is taken as the type for these, what is known of the development 
of other forms, especially Cavia^ being duly mentioned, considerable 
space being devoted to the consideration of the structure of the foetal 
envelopes and placenta. The general conclusions as regards the formation 
of the latter organ and its taxonomic value are reproduced in the paper 
quoted below. 
-. On the Evolution of the Placenta, and on the possibility of em- 
ploying the Characters of the Placenta in the Classification of Mam- 
mals. P. Z. S. 1881, pp. 210-212. 
The importance of a knowledge of the development of the placenta is 
insisted on, as apparently similar forms of placenta may arise in quite 
different ways.
