Wallich, G. C. On the vital functions of the Deep-sea Protozoa. 
Monthly Microscopical Journal, January 1869, pp. 32-41. 
The object of this paper is to establish that in the lowest sub- 
division of the lowest order of the animal kingdom, where even 
a definite nucleus^^ and “ contractile vesicle^^ are absent, nutri- 
tion is effected by a vital act, which enables the organism to 
extract hydrogen, oxygen, carbon, nitrogen, and lime from the 
surrounding medium, and to convert these ingredients into sar- 
code and shell-material. The author also objects to tlie suffi- 
ciency of the evidence on Avhich the genus Bathybius of Huxley 
is founded, and shows that there is not necessarily any connexion 
between it and the development of Coccoliths and Coccospheres.

scribed {pide special part) ,
