REVIEWS. 189 



when these methods are used are carefully described and 

 figured. Professor Schafer's book is remarkable for the care 

 with which it has been prepared, and derives special value from 

 the fact that the author is himself constantly engaged in 

 testing and expounding by practical demonstration to his pupils 

 the importance and significance of the modes of studying the 

 tissues which he recommends. The book is illustrated with 

 numerous good woodcuts of bits of useful apparatus. 



Amongst works descriptive of the tissues, the translation of 

 Professor Prey's ' Compendium ' cannot fail to be popular with 

 students. It is not an exhaustive work, but runs rapidly over the 

 subject, omitting the doubtful and dwelling on the essential and 

 well-established teachings of histologists. It is copiously illus- 

 trated, and the style throughout is lively and interesting. The 

 translator has adhered so closely to the words of the original that 

 he has occasionally failed to give the author's meaning. 



We have placed Dr. Michael Foster's work in the list at the 

 head of this page because in it he adopts a method of teaching 

 histology which we are inclined to think is the right one, when it 

 can be carried out. Dr. Foster deprecates pure histology and the 

 making of endless beautiful preparations. He prefers when once the 

 student has learnt to use his microscope and mastered the outlines 

 of the anatomy of the tissues, to make his further study of 

 microscopic anatomy advance pari passu with the experimental 

 study of the properties and functions of tissues and organs. 

 There can be no doubt that it is only by close association with 

 the life-giving hypotheses of either physiology or of evolutional 

 morphology that a healthy cultivation of the refinements of 

 modern microscopy is possible.
