 edition) ; Huxley & Martin's " Text-Book of Physiology ;" Dr. 

 Nicholson's "Manual of Zoology;" Huxley's "Lessons in 

 Elementary Physiology," and Wilson's "Zoology" (published 

 by Chambers) are all good books for the object you seek. 



H. K. Moiser. — The list of desiderata for the Botanical 

 Exchange Club has not been sent out this year, as it was thought 

 that of last summer might stand.

 our best thanks for the botanical specimens forwarded to us. 



Mr. J. G. Osborne, who is engaged in some observations 

 on the development of the embryo in invertebrate ova, wishes 

 to know of some preparation which would render the structures 

 more transparent, and arrest and preserve them at different 

 stages (see article in our March number on " Preserving delicate 

 Organisms," and paragraph in this number under head of 

 "Microscopy").
