THE IMPORTANCE AND THE PROMISE IN THE 
STUDY OF THE DOMESTIC ANIMALS.* 
Iv is believed that for the advancement 
of science, no better service can be rendered 
by those of considerable experience as teach-

ers and investigators than to point out to 
their younger brethren lines of study and 
research which are, on the one hand, im- 
portant, and on the other promising of re- 
sults. I have, therefore, selected for the 
subject of this address before the section of 
zoology a plea for the study of the domestic 
animals. The young zoologist may right- 
fully ask the grounds for studying this 
heterogeneous, greatly modified series of 
animals. In the first place it must be con- 
fessed that for the animal kingdom as a 
whole it appeals mainly to a single one of 
the twelve phyla in the animal series given 
by Parker and Haswell—that is, to the ver- 
tebrates. The other eleven phyla—that is, 
the whole of the invertebrates except the 
arthropoda--are ignored. I wish to express 
very clearly and emphatically at the outset 
that the plea will not be made because the 
domestic animals seem to me alone worthy 
of study by zoologists, or that they are in 
all cases the best possible representatives 
of their group. It is most earnestly be- 
lieved, however, that in the whole range of 
zoology no forms offer a greater reward for 
the study of the problems of life, especially 
in the higher groups, than the domestic 
animals. The importance of the study 
cannot be overestimated from a purely sci- 
entific standpoint, and certainly if the pros- 
perity, happiness and advancement of the 
human race are put in the count the subject 
is of transcendent importance.
