ANIMAL MORPHOLOGY IN ITS RELATION 

 TO OTHER SCIENCES. 



In the system of classification adopted 

 by the organizers of this congress the sci- 

 ence of animal morphology is apparently 

 to be defined so as to exclude comparative 

 anatomy. I take it, consequently, that it 

 is intended to include only the broader 

 problems connected with the form of ani- 

 mals—such as the phylogenetic evolution 

 of form, the embryological development of 

 form and the restoration of the mutilated 

 form — in general, the form-producing and 

 form-maintaining factors. 



Expressed in this way the relations of 

 animal morphology become more evident; 

 and clearly the first and most intimate of 

 these relations is with the morphology of 

 plants. The separation of animal mor- 

 phology from plant morphology in the de- 

 partment of biology, while according with 

 a division of the subject found to-day in 

 our iiniversities, is, I think, not an ideal 

 condition. For the form-producing and 

 the form-maintaining factors are, at bot- 

 tom, the same in all organisms. The prob- 

 lem of what factors have worked to de- 

 termine whether a fish or a man shall have 

 such and such a form is identical with that 

 of the determination of the form of a fern 

 or an oak. Little by little the morpholo- 

 gists that deal with the broader aspects of 

 their science are being forced to face the 

 absurdity of its division on the basis of the 

 material studied. In cytology it is found 

 that the maturation of the germ-cells, the 

 fertilization of the egg and cell-divisions, 

 are identical processes in the two 'king-
