Tapiravus (Marsh) of the Upper Miocene. Tapirus is first found 
in the Upper Miocene of Germany (Epplesheim). The recent 
species of the family belong to Tapirus L., and Elasmognathus 
(Gill. 
The three genera are distinguished as follows: 
Two superior premolars different from true molars ;.. Zapiravus Marsh. 
One superior premolar different from true molars; 
no heel of third inferior molar; nasal septum 
: 
cartilaginous : 
Tapirus L. 
Like Tapirus, but nasal septum osseous ;........+.++0 Zlasmognathus Gill. 
The order in which these genera stand above, represents their 
phylogenetic as well as their taxonomic relations, the oldest genus 
standing first. 
(To be concluded.)

To discover the relation of mind to matter is the goal of 
Scientific research, and every addition to knowledge may be 
fegarded as a contribution to this subject. The advent of Neo- 
Lamarkianism brings the question immediately within the 
view of the student of natural history, where it belongs, and 
brings it out of the metaphysical limbo, where it has so long 
lain neglected by science. The evidence that the environment 
_ 'S not the only factor in evolution is abundant enough, and 
a attempt to restrict the remaining factors to “ heredity” has 
"ot long satisfied the mind of science. The evidence that the 
Movements of animal organs and tissues is the other factor, con-
