From J. T. Moggridge   24 July 1873

My dear Sir

I am most truly obliged to you for your letter received this morning; for I now clearly understand how to set about making the proposed experiments—¹

I am quite eager to begin, & shall probably make a commencement shortly.

With me, & I fancy with many others, the uncertainty as to the best method of conducting an experiment is very often the cause of shirking it altogether.

Here the training of an experimental school of physiology might I think prove of use—.

The question “how am I to set about it” often meets with the reply “I’m sure I dont know”; or, if the questioner is more determined, it results in “I dont know, but I’ll try first this way, then that”.

Believe me, with renewed thanks, | y^rs. most truly | J. Traherne Moggridge
