Remarks. — The accompanying plate has been prepared and en- 

 graved by myself, and it may seem hardly necessary to state is not 

 up to the standard of high artistic merit. It is to be hoped that the 

 sketches will assist the student in forming a better idea of the curious 

 sexual differences, so difficult to express in words, than could be 

 obtained by description only.
