Summary:
Ogle will keep JT’s suggestion in mind in observing less hairy races of man and the lower animals.
Asks JT whether he can help Ogle on a troublesome point on the colour of tissues with olfactory nerves, and the relation of colour to the absorption of odours. Does JT’s respirator deprive odorous substances of their smell?
