I am very sorry to hear that you have been so seriously ill. You will have to take to my way of living—a mutton chop a day and no grog, but much baccy. Don't begin to pick up your threads too fast.

No wonder you are uneasy if you have crabs on your conscience. [I.e. an article for the "Encyclopaedia Britannica.">[ Thank Heaven they are not on mine!

I am glad to hear you are getting better, and I sincerely trust that you may find all the good you seek in the baths.

As to coming back a "new man," who knows what that might be? Let us rather hope for the old man in a state of complete repair—A1 copper bottomed.

Excuse my nautical language.

Cragside, Morpeth, August 11, 1875.

My dear Foster,

We are staying here with Sir W. Armstrong—the whole brood—Miss Matthaei and the majority of the chickens being camped at a farm-house belonging to our host about three miles off. It is wetter than it need be, otherwise we are very jolly.

I finished off my work in Edinburgh on the 23rd and positively polished off the Animal Kingdom in 54 lectures. French without a master in twelve lessons is nothing to this feat. The men worked very well on the whole, and sent in some creditable examination papers. I stayed a few days to finish up the abstracts of my lectures for the "Medical Times"; then picked up the two elder girls who were at Barmoor and brought them on here to join the wife and the rest.
