13th January 1862.
Dear Sir.
I was very much gratified by the reception of your note of the 1st June last, in relation to my article on Macrauchenia in Bolivia.1 I am thereby encouraged to address you on a different subject.
Having paid for some years careful attention to the distribution of recent and fossil Mammalia in South America, I am very anxious to obtain some information which I apprehend you alone can give me, as the materials which my friend Professor Owen2 possesses have been already placed at my disposal.
I would ask firstly, where is any scientific anatomical description of the bones discovered at Manta, Punta St Elena, Papallacta, & Suacha to be found? Humboldt identifies some of these remains as undoubtedly Cetacean.3 Has this been verified, and if so, where?
Secondly, whether during your many investigations, you are aware of any other species of fossil New World monkeys than Pliopithecus antiquus.
Cebus macrognathus.
Callithrix primævus, &
Jacchus grandis.
and if any other species exist, in what work or periodical I may obtain information respecting them?4
I may add, that I am the author of the paper on “Distribution of Mastodon in South America” (Geologist. Novr 1861)5 and that I have prepared a list of the recent and fossil Mammalia of Chile & Peru, which will appear in the forthcoming 2nd Edition of my friend Mr Bollaert’s work on South America.6
I have the honour to remain, | Dear Sir, | Yours very respectfully | Charles Carter Blake
