My dear Sir
I [would] like to thank you for so kindly taking the trouble of communicating the Rat V. Rabbit case.2 I am very glad to have all such facts, but it is doubtful whether I would require to use it, so I will not give trouble to your informant of inquiring.
With many thanks, pray3 believe me my dear Sir | Yours sincerely | Ch. Darwin
