Dear Mr Archibald

I regret giving you the trouble of writing for the letter to Mr Todd. I had not forgotten it. …………. the advertisements did not think ……… wanted it so soon. ……. enclose it and hope it may be of use to you. Short of going to Western Australia: I know of no better person than Mr Todd to give you information…… the subject. ………………… I am sorry to say is not improving and is rather low spirited. If ………. better for him to his own doctor in London asking advice.

Generally …… and …… cyclones …………… ……. but it often ……. appears that small one …….. an intensity and ……………… ……… that of the large ones.

I have been reading Ferrel and thank him for new light on many points but cannot go with him altogether. So far as I have read. It is a cleverly written book and apt to make one think that there is a good deal of formula applicable to meteorology: upon which calculations can be made. but it has yet to be shown how far we can apply them.

For instance in the laboratory we know something about laws of diffusion of gasses and heat but where are the experiments which give us these laws as modified in nature by currenting air?
Yours very truly
H.C. Russell
