My dear Sir,

Your reply to my note reached me a day or two since. I hope to be able to accept your invitation on the morning of Saturday next. When I expect to spend a few hours in Milwaukee. I am exceedingly anxious to learn what I can about this interestting region before the cold weather sets in. Accept my

thanks for your Kindness.

You seem to intimate that I asked you to write down "All you Know" about the place I do not think I could have made such a mild request as that.

I am Sir Yours sincerely

Roland Irving.

Dr. Lapham,

Dear Sir,

You will have observed in the papers, that, at the late fire in Chicago, I lost my Entire Collection of Nat. History insects, shells, fossils, books and private papers. Everything except the collection I had in the Exposition in Cincinnati. It was a severe loss, and has quite crippled one, for the collection of butterflies alone number over 2,000 species. all your shells, & many others went with the wreck. Now if you could spare one a few duplicates of shells of Wisconsin, it would be a great favor, & I would doubly appreciate it at this time most
