iv PREFACE 



Only those methods are recommended upon which long experience 

 has proved that full dependence can be placed, but the directions given 

 are for the most part capable of easy verbal modification in accordance 

 with the ideas or experience of different teachers. 



For other processes and more minute details than could suitably 

 be given here the student is referred to manuals which are devoted to 

 practical work, such as the ' Practical Physiology ' of Prof. Foster and 

 Mr. Langley, the * Practical Histology' of Prof. Eutherford, the 

 ' Textbook of Practical Histology ' of Prof. Stirling, and the author's 

 4 Course of Practical Histology.'
