PREFACE. 



THE object of this small work is to lay before the 

 practitioner and student of medicine, a few concise 

 and simple methods, by which the various tissues of 

 the body may be prepared for examination with the 

 microscope. 



I do not claim any originality in these methods, but 

 I recommend them from my own personal experience 

 as the best, easiest, and cheapest to carry out. 



The use of dyes for staining the tissues is a com- 

 paratively new branch of the science of Histology, and 

 its value is being proved every day. 



I have been engaged in experiments with all the 

 various colouring agents for a long time, and in trying 

 their effect in double and treble staining, and I have 

 given the result of those which have proved most suc- 

 cessful hitherto. I have also added a list of the aniline 

 dyes, those soluble in water, and those soluble in spirit, 

 which will be found very useful by anyone wishing to 

 make experiments in staining.
