202 METHODS OF MICROSCOPICAL RESEARCH. 



In bidding farewell to his readers the author 

 ventures to express the hope that the results of his 

 thirty years' experience in microscopy and micro- 

 scopical manipulation, as embodied in this treatise, 

 may tend to simplify the work which has lost none 

 of its interest or attractions for him, and that those 

 who may be induced to prosecute this delightful 

 pursuit may be enabled thereby to far surpass any 

 results or achievements upon which he may venture 

 to consider he is entitled to congratulate himself. 

 At least he may affirm that his work has been 

 always prosecuted with the most sincere desire and 

 endeavours to produce the best results and to 

 advance true microscopical science.
