Hybridity in Animals by Dr. S. Morton chiefly drawn from Griffith's Animal Kingdom (Edition of Cuvier) from do (p. 43) Ox has crossed with Bos. gavæus quotes Brandes Ency. & Owen as authority! That Bull & Sheep have crossed!!

p 45. refers to Cuvier Regne animal I. p. 187 for crosses of Camel & Dromedary & fertile offspring

p. 47. the late Mr. T. Say regarded Indian dog of N. America as domesticated Canis lutrans uniform in character over immense territory hybrids with common dog fertile

p. 204. Dr. M. has met 2 hybrids of common Fowl & Guinea fowl, "one of them looks more like

[133]

(2) common fowl: the other has much stronger resemblance to Guinea fowl." sounds intermediate - has heard in U.S of 3 other case - have had no progeny, see Proc. of Acad. Nat. Sc. Philadelp sept. 1846 - quote Bechstein for cross of Cock of wood with fowl & turkey & for crosses with Redpole F. linaria with other finces for other with Canary & Siskin & remarks on their origin - Griffith for fertile crosses between F. citrinella & Canary & Veillots' opinion on same.

p 206. quote Chevreul in Journal des Savans June 1846 for 7 generations of common goose with A. cygnoides.

p 207. cross in wild state between A. boschas & obscura. v. Loudons Mag. IX. p. 615 - gives case of cross of A. boschas tame & probably A. rurfitorques

p 208. Mr. Haldeman suspects he has seen hybrids between Unio radiatus & siliquoideus & Paludina decisa & ponderosa.

p 212. "The capacity for fertile Hybridity caeteris paribus exists in animals in proportion to their aptitude for domesticity & cultivation" ( [illeg] no doubt must be domesticated ie must breed under confinement)

p 207. "Selby mentions a male wigeon breeding with female pintail, notwithstanding female of his own species being kept on same piece of water."

Vol 4. p. 425. 1847. Agassiz in letter to Murchison writes trace "close analogy between the fossil Flora of of the European miocene deposits & the living Flora of temperate part of the U. States the correspondence extends to all the types of organized beings" Think climate was not tropical when strata of Oeningen were deposited."

In Japan "we have the Megalobatrachus, the corresponding living type of the great fossil Salamander of Oeningen"

p.133. S. S. Haldeman says "The N. American forms of the Longicornia seem to have a nearer relation to those of Europe than to those of S. America, the same genera being mostly found in both regions, to which some of the N. forms are almost entirely confined."

Good case for me, as from habits wd. not likely to extend into Arctic regions.
