SCIENTIFIC SUMMAKT.

molluscs, 2,000 species of fishes, 800 species of reptiles, 21,000 birds, with 
the nests of 200 and the eggs of 1,500 species, 1,000 mammals, and nearly 
900 skeletons and pieces of osteology. Most of the species are presented by 
four or fiye specimens, so that, including the archaeological and ethnological 
cabinets, space is required now for the arrangement of not less than 400,000 
objects, as well as for the accommodation of a library of more than 22,500 
volumes. A new building to cost half a million dollars is now in process of 
erection. 
The Anatomy of the Negro. — Professor Agassiz is well known as a believer 
in the view that the different races of man are specifically distinct. But in a 
recent lecture, as reported by one of the American journals, he seems to have 
gone too far. He says : I have pointed out over a hundred specific differ- 
ences between the bonal and nervous systems of the white man and the 
negro. Indeed, their frames are alike in no particular. There is no bone 
in the negro’s body which is relatively the same shape, size, articulation, or 
chemically of the same composition as that of the white man. The negro’s 
bones contain a far greater proportion of calcareous salts than those of the 
white man. Even the negro’s blood is chemically a very different fluid from 
that which courses in the veins of the white man. The whole physi- 
cal organisation of the negro differs quite as much from the white man’s as 
it does from that of the chimpanzee — that is in his bones, muscles, nerves 
and fibres, the chimpanzee has not much farther to progress to become a 
I white man. This fact science inexorably demonstrates. Climate has no 
more to do with the difference between the white man and the negro than it 
j has with that between the negro and the chimpanzee, or between the 
horse and the ass, or the eagle and the owl. Each is a distinct and separate 
I creation. The negro and the white man were created as specifically different 
j as the owl and the eagle. They were designed to fill different places in the 
system of nature. The negro is no more a negro by accident or misfortune 
j than the owl is the kind of bird he is by accident or misfortune. The negro 
1 is no more the white man’s brother than the owl is the sister of the eagle, or 
the ass the brother of the horse. How stupendous and yet how simple is 
the doctrine that the Almighty Maker of the universe has created different 
species of men, just as He has different species of the lower animals, to fill 
j different places and offices in the grand machinery of nature.” 
i Non-parasitie marine Copepoda of the north-east of England. — A very full 
j list of these, accompanied by a capital pair of plates, has been published in 
I the Nat. Hist. Trans, of Northumberland, &c.,” by Mr. George S. Brady, 
i C.M.Z.S. [vol. iv. part ii.]. He states that this list, though embracing all the 
1 species at present known to him as inhabiting this district, must be taken 
j only as an instalment of what an exhaustive survey would no doubt reveal. 
[ The examination of these little creatures is exceedingly tedious and laborious, 
^ the points of difference being often indistinguishable except with tolerably 
I high microscopic powers. Thus a very small gathering, if it contain any 
! great variety of species, will often occupy many hours in its examination. 
By far the greater number of species noted by the author or described by 
j foreign authors are free-swimming animals ; some have a special predilection 
I for the fronds of fuci, and others for muddy localities or the bed of the sea ; 
but little is yet known of the ground-inhabiting forms, and among them
