heredity which is at once logically intact and biologically probable. 

 The theory of germ-plasm would then resemble that of stirp in all 

 points of fundamental importance, save that while the latter leaves the 

 question open as to whether acquired characters are ever inherited in 

 any degree, the former would dogmatically close it." These quotations 

 perhaps will serve to give the author's point of view.

Practical Biology. 1 



We deem it a pleasure to call the attention of educators to Pro- 

 fessor Dodge's manual. The book is intended for a laboratory guide, 

 and instead of instructions for dissection or descriptions to be verified, 

 the matter has been cast in the form of questions which can be ans- 

 wered only from the specimens. The types are so chosen and the 

 questions are so framed that the student should come out of the course 

 supplied not only with some zoological and botanical facts but with a 

 good introduction to Biology in the true sense of the term. From 

 this point of view the physiological studies upon each type are per- 

 haps of the greatest value, as they are far-reaching and yet not too 

 difficult for the tyro. In spite of the prevailing tendency, under the 

 influence perhaps of Professor Huxley's example, in American col- 

 leges, the author adheres to the logical and biological sequence, 

 proceeding from the simple to the more complicated. Many of our 

 best teachers will find the book more acceptable for this reason.
