——F. Gardiner, Jr., in a communication to Science, describes a 
natural bridge sixty-five feet long, fifteen feet wide where narrow- 
est and two feet thick in the center, situated in a small cañon at 
a distance of about twenty miles from the Atlantic and Pacific 
railroad, near the boundary of Arizona and New Mexico. 
Lieut. Hohm, of the Danish Greenland exploring expedition, 
separated from Dr. Eberlin at Tingmiarmint (62° 40' N. lat.) 
with the intention of reaching Angmaksalik, in 65° N. lat., where 
there is a fixed settlement not hitherto visited by Europeans. 
The heathen East Greenlanders are as tall as the peoples of North 
Europe, and mostly have dark eyes and hair. They seem to 
have nothing in common with the Eskimo, yet their utter absence 
of Norse tradition and total want of civilization, is thought to 
preclude the possibility that they are descendants of the Norse- 
men. 
GEOLOGY AND PALÆONTOLOGY. 
Tue RELATIONS OF THE PUERCO AND LARAMIE DEPOSITS.— 
Some writers having suspected the identity of the formations 
above named, and the consequence which follows, that the Puerco 
mammalian fauna was contemporary with the dinosaurian fauna 
of the Laramie age, the following observations on their strati- 
graphic relations are now given. They are derived from the notes 
of several years’ residence and exploration by my correspondent, 
David Baldwin, which connect those made by myself in New 
Mexico in 1874, published in the Wheeler Survey Report, with 
those made by Holmes and Endlich in 1878 in Colorado, and 
published in the Hayden Survey Report. 
At the locality where best developed, the Puerco beds have a 
thickness of about 850 feet, and contain Mammalia to the base 
(see Naturauist for April and May, 1885). The Laramie beds 
succeed downwards, conformably it is thought by Mr. Baldwin ; 
and have a thickness of 2000 feet at Animas City, New Mexico. 
They rest on Fox Hills marine Cretaceous of less thickness. A 
few fossils sent from time to time by Mr. Baldwin identify the 
Laramie. This is especially done by the teeth of the dinosaurian 
genus Dysganus Cope,! which is restricted to the Laramie
