Dear Sir

Many thanks for your letter and the information it contains.¹

I would venture to suggest that the virus² was over diluted: Will you repeat the Exper^t. with a stronger solution, say gr $\frac{1}{4}$ to [DRACHM]ss. (half a drachm of water) I return the little packet and if you require it can send you a little more;³ I need hardly say that I feel honored in furthering any scientific investigation that may interest you—.

The Question of its (cobra poison) action on ciliæ & on musculature, on topics generally apart from the nervous element shall be again investigated & the result communicated to you.—

I beg to send a copy of some investigations by D^r. Brunton & myself, since I returned to England—on the subject of Cobra poison.⁴ We are now engaged in an enquiry into the nature of the action of Crotalus poison.⁵

Have you seen my Indian book on venomous snakes?⁶ if not I should like to send you my copy.

Believe me | Yours very truly | J Fayrer
