Itemarks on the Ancient Peruvians. 335 



There exists — a very brilliant spot under the arrow of Sagittarius. 



here is — a very brilliant one in the shield of Sobieski. 

 We perceive — a brilliant one to the nortli and a little to the west of the 

 three stars of Aquila. 



We notice one long and feeble which follows the shoulder of Ophiu- 



chus. 

 We remark — three brilliant ones near the stars «, (i, and y of Cygnuf. 

 We distinguish three towards and within Cassiopea. 

 There is a very brilliant one in the hilt of Perseus* Sword. 



(Between x and y of Cassiopea, there exists a very obscure place.) 



No portion of the iVIilky Way resolvable by the telescope, 

 has exhibited to Herschel more manifest indications, and on 

 a larger scale, of the clustering power of stars, than the space 

 which separates /3 and 7 of Cygnus. By gauging this space, 

 according to the method already described, for a breadth of 

 about 5 degrees, Herschel found that 331 thousands of stars 

 might be counted in it. This immense group already pre- 

 sents a kind of division ; 105 thousand stars appear to pro- 

 ceed to one side, and 165 thousand to the other. 



Everything, therefore, justifies the opinion of this illus- 

 trious astronomer. In the series of ages, the clustering power 

 will inevitably bring on the fracture, rupture, and dislocation 

 of the Milky Way. 



Some Bemarks on the Ancient Peruvians. By Samuel George 

 Morton, M. D.* 



In my work on American skulls (Crania Americana), I 

 have expressed the opinion that the heads of the ancient Pe- 

 ruvians were naturally very much elongated ; and that they 

 differed in this respect from those of the Inca Peruvians, and 

 other surrounding nations ; and having given this opinion at a 

 meeting of the Academy prior to the publication of my work, 

 I take the present occasion to renounce it. 



In the American Journal of Science, for March 1840, 1 have 

 already, in a brief note, adverted to this change of opinion ; 

 and I now repeat my matured conclusions in connection with 

 positive facts, derived from the work of a distinguished tra- 

 veller and naturalist, M. Alcide D'Orbigny.
