r surface of the vessel, A, is provided
with radial grooves, by which the rotary motion of the vessel is
communicated to the glycerine. To the center of the disk, C, is
attached a vertical rod, which extends downward through the hollow
shaft and is connected with governor valve. An increase of speed
throws the glycerine toward the periphery of the valve, and, raising
the disk, C, closes the steam valve; a diminution of speed permits the
glycerine to fall back, when the disk descends and the valve opens.

[Illustration: STENBERG REGULATOR.]

The disk, C, has a small aperture for the admission and escape of air,
and the apparatus is adjusted by pouring lead into the groove in the
disk.

The regulator shown in Fig. 2 operates upon the same principle, but it
is adjusted by means of a spring.

This apparatus is manufactured by Blancke Bros., Magdeburg.--_Musee de

A STRANGE PEOPLE.

Botel Tobago is an island in the South Seas which has lately been
visited by a party of United States naval officers. They were
surveying a rock east of the South Cape of Formosa, and called at this
island. They found a curious race of Malay stock. These aborigines did
not know what money was good for. Nor had they ever used tobacco or
rum. They gave the officers goats and pigs for tin pots and brass
buttons, and hung around the vessel all day in their canoes waiting
for a chance to dive for something which might be thrown overboard.
They wore clouts only, ate taro and yams, and had axes, spears, and
knives made of common iron. Their canoes were made without nails, and
were ornamented with geometrical lines. They wore the beards of goats
and small shells as ornaments.

Such is the account of these strange people given by Dr. Siegfried, in
a letter read at the last meeting of the Philadelphia Academy of
Natural Sciences.

REMEDY FOR THE NEW CARPET BEETLE.

Noticing a statement made by Mr. J. A. Lintner, to the effect that the
Persian insect powder would probably prove unavailing as a remedy
against the ravages of the new carpet beetle (_Anthrenus_), W. L.
Carpenter, of the U.S.A., was led to institute some experiments with
this well known insecticide, the results of which he communicates to
the current number of the _Naturalist_. A small quantity of the powder
was introduced, on the point of a penknife, under a tumbler b
