To John Tyndall   8 September 1870

Summary

CD finds JT’s discourse "grand and most interesting" [On the scientific use of the imagination (1870)]. Flattered by what JT says about him.

He is "a rash man to say a good word for Pangenesis for it has hardly a friend among naturalists".

CD is much struck with what JT says about "pondering" and delighted by his "as if" argument.

To John Tyndall   [27 February 1871]

Summary

Thinks JT’s discovery of a glycerine respirator is an interesting practical discovery. CD has been wondering about the hairs in our nostrils, but doubts that JT has explained their function, since there are hardly enough.

Will ask W. Ogle to observe hairs in nostrils of different races.

Letter no:  DCP-LETT-7518

To John Tyndall   1 March [1871]

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?
