This is a conversation of Shrlock Holmes and Dr. Watson.
I'm not sure of the usage of "should have thought".
“Wedlock suits you,” he remarked. “I think, Watson, that you have put on seven and a half pounds since I saw you.”
“Seven!” I answered.
“Indeed, I should have thought a little more. Just a trifle more, I fancy, Watson. And in practice again, I observe. You did not tell me that you intended to go into harness.”
How many pounds did Holmes originally think Dr. Watson put on?
Thank you in advance
