My dear D^r Lauder Brunton

Many thanks for your very kind & interesting letter— It seems strange that the glands sh^d have set you thinking of our tonsils.¹ I write now to beg a favour. I do not in the least know what others have guaranteed in relation to D^r. Ferrier—² Would 20 guineas be sufficient if not will you kindly take the trouble to have my name put down for 30 or 40 guineas as you may think best. If on the other hand no one else has guaranteed for as much as 20 guineas will you put me down for 10 or 15 guineas though I shd like to 20 best.

You can understand that I do not wish to be conspicuous either by too little or too much, so I beg you to be so very kind as to act for me. I have a multitude of letters which I must answer so excuse haste. Yours very sincerely | Ch. Darwin
