My dear Thwaites

It is extremely kind in you & your friends to take so much trouble about the fowls.1 If you have not the pure breed the results will of course be doubtful; & I am unwilling to believe that Blyth & Layard were both mistaken.2 I shd much like to hear whether the males of the black chickens spoken of by Mr Layard, undergo any change when they become adult.3 I have been very glad to see Mr Glenie’s letter;4 & shd you have any opportunity I hope you will return to him & to Mr Layard my sincere thanks

I am astonished at what Mr Glenie says about the elephants not contracting the orbicular muscle, for I & others saw this contraction plainly when the elephants trumpeted loudly in the Zool. gardens— Perhaps too great a contraction is expected.5

I received some time ago a very interesting & beautiful specimen from you shewing a surprizing difference in the form of the leaves.6

With very many thanks for all your kindness | yours very sincerely | Ch. Darwin
