From C. H. Browning   10 March 1879

Dear Sir:

While reading your work on the Origin of Species I came to that part, in which you treat of inherited effects and thinking that the following curious fact might be of some little interest to you I have taken the liberty of writing to you.¹

Several years ago a gentleman in Washington through sickness, became completely bald, after his recovery he married and has now five children, three sons and two daughters. At a corresponding age the three sons successively became as bald as their father while the daughters do not show the slightest signs of loosing their hair.

Do you not think this an astonishingly good example of inherited effects?
