Dear Sir
I am much obliged to you for your kind present of your Mem. on the “Pipéracées”.2 I am sorry to say that I have not sufficient knowledge of botany fully to understand all the points which you discuss, but I can see that some of them are extremely interesting.
I should be much obliged if you wd give my sincere thanks to your father for the extremely kind letter which he wrote me when in London;3 I should have written to him at once had I known his address. It caused me sincere regret that the state of my health prevented me attending the Congress & having the great pleasure & honour of conversing with your father.4
With my best thanks pray believe me my dear Sir | yours very faithfully. | Charles Darwin
