In many ancient burying mounds roùnd stones have been found ; 
these were ev idently used in making pottery, the wooden paddles 
which were probably placed with them having decayed. There 
is no difference between the modern article and these ancient 
- Stones found in the graves associated with pottery and other do- 
mestic articles buried with the dead.—Epwarp PALMER. 
Tue Berrres or Raamnvs' crocrus as Inpran Foop.— This is 
a fine evergreen, producing numerous red berries which render it 
very showy. The Apaches collect and pound them up with what- 
ever animal substances may be on hand, the berries imparting to 
the mixture a bright red color which is absorbed into the circula- 
tion and tinges the skin. On one occasion a detachment of the 
First Arizona Infantry Volunteers attacked a camp of Apaches 
in the Mogollon Mountains, northern Arizona, killed twenty-two 
and captured two children; the writer, being with the party as 
surgeon, examined the dead ; their abdomens were much distended 
from eating greedily of these berries and other coarse substances ; 
while their bodies exhibited a beautiful red net-work, the coloring 
matter having been taken up by the blood and diffused through 
the smaller veins. Among the captured stores were quantities of 
these berries dried, also much finely pounded meat and berries. 
A stohe mortar, near by, plainly told the purpose for which it had 
been used ; while numbers of rats and squirrels with the fur singed 
off, but otherwise entire, lay ready to form the next batch of mixed 
meat and berries. These Indians are not dainty, for they relish any 
part of an animal, even its viscera and blood. —Epwarp PALMER.

EE s Srenon stipe.—Mr. D. S. Holman of Philadelphia, 
whose life slide has recently: become a really useful as well as a 
popular accessory to the microscope, has contrived a modification 
of that accessory to be known as the siphon slide, in which living 
objects of suitable size and habits can be retained under observa- 
tion uninterruptedly for days or even weeks. A current of water 
or other fluid, of any required temperature, is made to flow con- 
tinuously through the chamber containing the object, so that the 
processes of respiration, circulation, digestion, and nutrition, the 
oe phenomena of inflammation, and the effects of some classes of 
Poisons may be studied at leisure and under perfectly natural or 
_ entirely controllable conditions. The habits of life of ‘small
