My dear Waterhouse
Many thanks for the enclosed interesting letter.—2 It always pleases me to see a clear-headed man on my side, & especially if he be bold enough to speak out, & thus render really efficient aid.— For it will require much speaking out before this side will receive fair toleration.—
Mr. Walsh has evidently been a close & good observer of Fishes.—3 What he says about the Sea-Trout in the Loch is very curious; & it would be very desirable that some professed Ichthyologist should examine these Trout.— It would make a good case for me.— But until thus examined & pronounced on, cavillers would simply deny that the fish was a sea-trout.—
I hope to see you before long, for I shall be up on the 21st to read a paper at Linn. Soc.—4
Did you ever look at the skull of the Borneo Domestic Cat, which I gave you?—5
My dear Waterhouse | Yours very sincerely | Charles Darwin
