Postscript. 



The foregoing memoir was originally contributed to the 

 Journal of Anatomy and Physiology, where it appeared in 

 January, April, and October 1878. A short notice of the male 

 generative organs has since been added. In reprinting, the 

 word "inaccurate" (p". 28 line 34) has been accidentally changed 

 to "accurate."
