The Races of Man by R. Knox 1850

p. 29 structures in the embryo represent permanent forms, "of whom some belong to the existing world … or finally forms which may be destined some day to appear"

p. 151. Gipsy race, "their ancient history is utterly unknown, in the mean time the climate of Britain has had much less effect on them than on surrounding Cheviot"

(Used)

p 201. The Bust of young Memnon in Brit. Mus. Knox then went almost on purpose to Rotterdam to see Jews & found perfect likeness of young Memnon. - But Nott & Gliddon in plate of Amunoph says a hybrid race, see to this. (see to this)

p 472 - In Britain tall men frequently die early of pulmonary consumption, & hence the greater mortality of the Foot-Guards. When sent to finer

climates, as the Cape & Australia such persons live readily. "The descendants also of the Saxon race seem to become a taller race in these latter countries, but this arises merely from the circumstances that the tall children, who wd. die in Europe survive at the Cape & in Australia."

p 473 Dr. Andrew Smith informs me "he attentively looked at a family descended from forefathers who came to S. Africa with the first settlers 300 years then had elapsed since their arrival. Their descendants at this moment are as fair as the fairest of Europæans.

p. 477 St. Hilaire was explicit enough many years ago "There is but one animal, not many."

I must admit that by direct evidence it is doubtful whether there is any good evidence of change in races of men within historical period. Can be deduced only by indirect evidence, as with the races of domestic animals & plants, & species generally. There is, indeed, good evidence of no change within short periods of a few hundred years, as Andrew Smith & case from N. & Gliddon in West Indies. With respect to gypsies, we have no really accurate standard for several hundred years, except their comparison in different parts of Europe at present day.

So with Ægyptian monumental drawings: I do not doubt, of course, negro & other races but there is no evidence of no very

slight & insignificant changes. Here give if the case turns out good. Knox & Nott & Gliddon on young Memnon.

In an animal, which seem on variation view to have varied so much I am surprised at such cases of gypsies, even Andrew Smith &c case. According to analogy in less variable animals I shd expect that most race wd be permanent, here & there one vary & the other become extinct & I suppose this analogy must even in man hold good. Welsh & Irish & even Yankees show some change: we have only to multiply. – Fuegians & Brazil, climate & habits of life so different good instance of how fixed races are, in face of very different external conditions. The slowness of any changes explained by constitutions selection & sexual selection.
