should not be forgotten that the true purpose of systematic work 
must be to increase our knowledge of the relationship of animals 
of any special group already known, and serve in some way as 
connecting link in the chain of the various branches of Zoology, 
We have our memoirs of systematic Zoology, of Psychology, of — 
Paleontology, of Comparative Anatomy, of Histology, ete., 
ing of their respective sciences as isolated departments and 
strongly biassed by the characteristics of the sciences from which 
they originated. Comparative Anatomy, and Physiology as well as 
Histology, are the children of Human Anatomy, and this, in 
turn, was gradually developed from the needs of medicine. 
bryology and Paleontology, though so intimately connected, 
rarely treated together, the latter being considered to belong, 
birthright, to Geology. Psychology is but now becoming emanci- 
pated from speculative Philosophy. We have, however, no recent 
memoir on Zoology in the Aristotelian sense ; the sciences formi = 
the branches of Aristotelian Zoology stand upon separate pedes- 
tals. They have grown up independently of one another, yet th 
all converge towards a common point, each an important part 
the life history of every animal, and the common link whieh is 
unite thém all is (when rightly understood) systematic Zoology: 
Working in this spirit, systematic Zoology helps us in our at- 
tempts to undergtand the laws of nature; these must remain 
intelligible to him who is busy with naming and classifying 
rials, reducing his science to an art, merely accumulating ! 
to be stored in museums, forming as it were a library of nat re, 
To him its books will be inaccessible and its laws as inexplica 
as are the laws of the motions of the planets to one who has 
knowledge of the existence of gravitation.
