Sir
Understanding from Mr Murray that another edition of your ‘Varieties of Animals & Plants under domestication’ is likely, I take the liberty of saying that I have had some experience respecting the Black-winged Peafowl described at some length in your book—1
If there is any question referring to this singular bird, which you would like to ask, it would give me great pleasure to place all information I possess on the subject at your service—
Trusting you will excuse the liberty of addressing you | I am, Sir, | yr obedient Servant | ASG Canning
Charles Darwin, Esqre | &c. &c. &c.
