Oxyhydrogen
(gcide) | Oxyhydrogen \Ox`y*hy"dro*gen\, a. [Oxy
(a) + hydrogen.] (Chem.) Of, pertaining to, or consisting of,
a mixture of oxygen and hydrogen at over 5000[deg] F.
[Webster 1913 Suppl.]
Oxyhydrogen blowpipe. (Chem.) See Blowpipe.

to use the light produced by burning lime or limestone
under a current of oxyhydrogen gas.

[1913 Webster]Blowpipe \Blow"pipe`\, n.
1. A tube for directing a jet of air into a fire or into the
flame of a lamp or candle, so as to concentrate the heat
on some object.
[1913 Webster]
Note: It is called a mouth blowpipe when used with the mouth;
but for both chemical and industrial purposes, it is
often worked by a bellows or other contrivance. The
common mouth blowpipe is a tapering tube with a very
small orifice at the end to be inserted in the flame.
The oxyhydrogen blowpipe, invented by Dr. Hare in
1801, is an instrument in which oxygen and hydrogen,
taken from separate reservoirs, in the proportions of
two volumes of hydrogen to one of oxygen, are burned in
a jet, under pressure. It gives a heat that will
consume the diamond, fuse platinum, and dissipate in
vapor, or in gaseous forms, most known substances.
[1913 Webster]
2. A blowgun; a blowtube.
[1913 Webster]
Blowpipe analysis (Chem.), analysis by means of the
blowpipe.
Blowpipe reaction (Chem.), the characteristic behavior of a
substance subjected to a test by means of the blowpipe.

Oxyhydrogen light
(gcide) | Oxyhydrogen light \Oxyhydrogen light\
A light produced by the incandescence of some substances,
esp. lime, in the oxyhydrogen flame. Coal gas (producing the
oxygas light), or the vapor of ether (oxyether light) or
methylated spirit (oxyspirit light), may be substituted for
hydrogen.

[1913 Webster]Microscope \Mi"cro*scope\, n. [Micro- + -scope.]
An optical instrument, consisting of a lens, or combination
of lenses, for making an enlarged image of an object which is
too minute to be viewed by the naked eye.
[1913 Webster]
Compound microscope, an instrument consisting of a
combination of lenses such that the image formed by the
lens or set of lenses nearest the object (called the
objective) is magnified by another lens called the ocular
or eyepiece.
Oxyhydrogen microscope, and Solar microscope. See under
Oxyhydrogen, and Solar.
Simple microscope, or Single microscope, a single convex
lens used to magnify objects placed in its focus.
