To Rudolph Heine   16 March [1865]1

Down, | Bromley, | Kent. S.E.

Mar 16


I am much obliged for your letter of Mar 10th.

I am pleased to hear that you have been interested in my work on the Origin of Species. Your law of inheritance I dare say is true & may have some bearing on the modification of species; but I fear it would be difficult to prove it with sufficient clearness to allow of its use2

I beg to remain | Dear Sir | Yours respectfully | Charles Darwin
