Dear Sir

I send you by mail an advance copy of the last chapter of my work to which reference is made in the article before the Boston Academy which I sent to you some time ago at the suggestion of Prof Asa Gray of Cambridge.² The work is not yet issued, although stereotyped: but it will be about Dec 1. Until it is issued by the Smithsonian Institution, I suppose it should be considered as a private communication.

In a general sense the results of my investigations are in harmony with the Darwinian theory so far as man is concerned: and it occurred to me that you might be glad to look over this chapter in advance.³ Although apart from the remainder of the text, and the Tables, the force of the positions taken cannot be fully appreciated.

It must be the next work of Ethnology to study with more care the ages of barbarism, to fix the great and successive stages of progress through it, and to find the sequence of customs and institutions which created these epochs. The most interesting and the formative portion of mans physical and mental history lies in the barbarous ages. The stages of his progress were numerous, and by successive reformatory movements as I think each resulting in the creation of new—or in the further developement of old institutions

I intended to call upon you to pay my respects—and to that end provided myself with a letter of introduction from Prof Gray: but I fear now I shall be compelled to forego it until my return to England in the Spring

With great respect | Yours truly | L H. Morgan

The first of living Englishmen | Charles Darwin.

As your country has given you no title I take the liberty of adding an American designation
