SOME ASPECTS OF PROGRESS IN MODERN 

 ZOOLOGY-^ 



It is our privilege to live in a time of 

 almost unexampled progress in natural sci- 

 ence, a time distinguished alike by dis- 

 coveries of the first magnitude and by far- 

 reaching changes in method and in point of 

 view. The advances of recent years have 

 revolutionized our conceptions of the 

 structure of matter and have seriously 

 raised the question of the transmutation of 

 the chemical elements. They have con- 

 tinually extended the proofs of organic evo- 

 lution but have at the same time opened 

 wide the door to a reexamination of its 

 conditions, its causes, and its essential 

 nature. Such has been the swiftness of 

 these advances that some effort is still re- 

 quired to realize what remarkable new hori- 

 zons of discovery they have brought into 

 view. A few years ago the possibility of 

 investigating by direct experiment the 

 internal structure of atoms, or the topo- 

 graphical grouping of hereditary units in 

 the germ-cells, would have seemed a wild 

 dream. To-day these questions stand 

 among the substantial realities of scientific 

 inquiry. And lest we should lose our heads 

 amid advances so sweeping, the principles 

 that guide scientific research have been sub- 

 jected as never before to critical examina- 

 tion. We have become more circumspect in 

 our attitude towards natural "laws." "We 

 have attained to a clearer view of our work- 

 ing hypotheses — of their uses and their 

 limitations. With the best of intentions
