No. VII.—ODOUR. 
By Dr. BEDDOE, F.R.S. 
Many curious things are known or reported on this subject. 
Thus the Peruvians have different names for the scent of a 
Negro, an Indian, and a white man. The North-American 
Indians regard the smell of Jews as horribly offensive. The 
odour of Kaffirs is said not to be diminished by washing, but to 
be increased by muscular exertion. 
1. Is there any notable peculiarity of odour attached to the 
persons of the tribe or people described ? 2. Is it recognized 
as diagnostic by their neighbours, or by dogs or other animals ? 
3. Does it seem to depend on filthy habits and neglect of ablu¬ 
tion, or on any favourite cosmetic or unguent, or on peculiarities 
of diet ? or to be natural and constitutional ? 4. Does it belong 
equally to both sexes and to all complexions (where these latter 
vary) ? 5. Does it vary at different ages ?
