CHAPTER IX. 



ON THE DEVELOPMENT OF THE NYMPH IN THE PUPA. 



Dr. Weismann's great work [2] on the after-development of 

 the Muscidae was the first memoir on the subject which can be 

 regarded in the light of a scientific exposition. When we 

 remember the primitive modes of histological research which 

 were then in use, and the unsettled state of the opinions 

 entertained as to the manner in which the tissues of the animal 

 body are developed, we must regard this memoir of Weismann's 

 as one of the most wonderful records, if not the most won- 

 derful record, of brilliant discovery which has appeared in 



Bibliography.
