Tue “Grapes” or MaryLanp.— Will you call the attention of 
geologists who may be passing over the Baltimore and Ohio rail- 
road to this very peculiar region? From a bird’s-eye view which 
I had from a summit, a little north of Oakland station, in Alle- 
ghany county, I am satisfied that these meadows were the seat of 
ancient glaciers. If this is so, it brings the former glacier level 
of the Alleghanies much lower than has heretofore been supposed ; 
that is to say down to 2400 or 2500 feet above mid-tide at Balti- 
more. — GEORGE GIBBS, New Haven. 
Bowtpers.—I believe it has long been known that in many 
cases bowlders are formed by exfoliatign and disintegration in the 
very situations in which we find them. Fine examples of granite 
owlders of this sort occur near the ordinary stage road about 
five or six miles, more or less, north of the Yosemite.— SANBORN 
TENNEY. 
ANTHROPOLOGY. 
Tue Ace or THE Famous GAupELoure SKELETON.—M. Hamy 
has just made, at the Museum of Natural History at Paris, a dis- 
covery of much interest in relation to the age of the famous 
Gaudeloupe skeleton. He found in one of the blocks containing 
a skeleton of a child eight years old, an amulet of jade, represent- 
ing a batrachian. This jewel he pronounces to be of Carib origin. 
Rochefort and Du Tertre speak of the fondness of the primitive 
inhabitants of this archipelago for certain green and red stones, 
and especially those which had the form “grenouille” (frog). i” 
block was carried to Paris at the same time as the one enclosing 
the skeleton examined by Cuvier. Abridged from the Parts

MICROSCOPY. 
A New Camsey For Microscope Lamps.—Mr. Wenham uses 
as a chimney a cylindrical brass tube with a space cut out of ane 
side, which space is closed with an ordinary glass slide held in 
place by a spring clip. The tube is not liable to accident, and 
the perishable part, the glass slip, can be instantly replaced wher- 
ever the microscgpist may be, while the peculiarly shaped glass 
chimneys, commonly used on microscope lamps, cannot be obtained
