SCIENTIFIC MISCELLANY.

Investigating the mysterious noises
common In Italy. where they ana
known as "hronudi," Prof T. Alippi.
Of The Trhins observatory has sent
inquiries TO 2l7 persons. OF whom 1876
On various parts OF italy and its A.
rican c0lOuies-have noticed the
phenomenon. The sounds. which re-
sCmble the rumble OF distant eNplos-
ions. are popularity explained as echoes
from strong tides at sea. They occur
usually I'm the afternoon, both sum
mer and winter, with bright sky and
calm air. but are supposed TO give
warning or bad weather Prof. Al
lppi finds no evidence that they are
due to mine explosions or gun firing.
They occur chiefly in central noun
tain regions, but do not seem TO be
caused by wind or thunder and tho
investigator is stin iu doubt as 20
whether they result from meteoro-
logical or earthquake causes.

The apparatus Tor making black dia-

Bonnet consists Of a vessel Of bronze
or other metal with two carbon cleo
frodes. between which Is "a rod Of pure
carbon. while beneath the rod Is a
small vessel containing carbon bisul-
phide. The passage OF a slight electric
current vaporizes the carbon bisul-
phlde. A high tension current passed
through the Theoretically closed veH-
sci causes the yapor 20 yield "a high
