Letters from Watson: The Engineer's Thumb
Part 1: The Fun Bits
Hatherly is "exceedingly pale" and Watson mentions agitation as a cause even though he's already noted the possibility for excessive blood loss, and that railway cases are "seldom trivial." Hooray for Victorian medicine.
Fun fact: if you're fainting from blood loss you already need a transfusion. As of '89 we are two decades before safe (relatively) blood transfusions, when the ABO clotting factors were discovered. However, given the pain and stress, the cause of Hatherly's fainting doesn't have to be hypovolemic shock. Hatherly did just lose a thumb.
A carbolised bandage would have been a bandage treated with phenol (carbolic acid) as a disinfectant. I would not recommend raiding Watson's stash for it, as carbolic acid can cause chemical burns.
I cannot decide if Holmes' habit of smoking all the leftovers of his previous day's pipes is gross or endearing.
In two years, Hatherly has earned 27 pounds and 10 shillings. (Using the trusty Bank of England inflation calculator, which does not DO fractions of a pound, this is just over 2,870 modern pounds, or $3590) He is not having a great start.
Reminder that a guinea is 1 pound, one shilling. 50 guineas is almost double the amount Hatherly has ever made in his entire practice. And yet the thing that actually makes him suspicious is that the consultation is scheduled for late at night, after the trains have stopped running.
Fuller's earth is a white, highly absorbent clay, used as a chemical filter and absorber. Actual mineral composition may vary, but the use it was named for was when wool processors (Fullers) would use it to clean oils and dirt from wool. This step would have been prior to spinning or felting the fiber.
A hydraulic press would be extremely unnecessary for shaping any kind of clay, since it's... clay. The first time I read this I confused Fuller's Earth with Diatomaceous earth, which is powdery in structure and therefore might need some kind of squishing to be formed into a brick.
I was unable to find any town or city named Eyford, so I'm assuming it's another slightly fictionalized location.
The horse trick here has always struck me as a clever insight on Holmes' part: of course, he is already aware that this is a scam of some kind, and that the secrecy measures would include a lot of misdirection
