What 5 interesting things did Mr. Holmes notice right away about Mr. Jabez Wilson?

From the text:

“Beyond the obvious facts that he has at some time done manual labour, that he takes snuff, that he is a Freemason, that he has been in China, and that he has done a considerable amount of writing lately, I can deduce nothing else.”

Mr. Jabez Wilson started up in his chair, with his forefinger upon the paper, but his eyes upon my companion. “How, in the name of good-fortune, did you know all that, Mr. Holmes?” he asked.
