190 RECOKUS OF THE AUSTRALIAN MUSEUM. 



Hoit. — The human subject. 



Ohs.—l am indebted to Prof. D. A. Welsh and Dr. H. G 

 Chapman, of the Sydney University, for much generous assis- 

 tance in my study of parasites affecting the human subject- 

 From the former, who kindly communicated with Dr. F. A- 

 Beimet, I learn that scahiea is fairly common amongst patients 

 presenting themselves at the Royal Prince Alfred Hospital. Dr. 

 Corbin, Medical Superintendent at the Sydney Hospital, informs 

 me that scabies is one of the commonest skin diseases ; and from 

 Dr. Chapman who, on my behalf, communicated with Dr. Noyes 

 of Melbourne, I learn that much the same condition of things 

 obtains in the Victorian capital.
