PROGRESS OF lNvENTIoN.-!Ihe great pro-
gress being made in natural and mechanical
science, especially in this country, at the present
time, is marked feature in the worlds history.
There are not less than three different plans,
more or less nlatured, now before the public IN
this City alone, purporting entirely to supersede
the use Of steam as Motive Power.
The most prominent before the public Is the
Electromagnetic Engine of Professor Page, late
" on exhibition at the Society Library Rooms
in this City, where model engines of six horse
power have been explained and examined by
capitalists and others. BY The introduction of
Electro magnetism it is claimed that cheaper
motive power, of equal efficiency with steam, is
secured OF the truth of this assertion time and
experience will have to decide.
The second plants that of Errickson's Caloric
En- inc, which is probeled by the rapid expan-
sion and exhaustion Of atmospheric air by means
of heat applied directly under the working cylin-
der. The construction OF this engipe is simple
and substantial and the cost of running it is said
to be only about one third that of the common
steam CINE The air is rapidly expanded by
means of IA liators of wire, and exhausted under
immense valves, weighing near twelve tons, in
the machine of 60 horse power now working at
the foot of Thirteenth ST., N. r.
1t is stated by the inv, ntor, that air is readily
condensed from 63l degrees Fahrenheit TO 1871,
in the fortieth part of one second and the caoric
or heat, Is retained to aid in expanding the next
charge, thus causing vast saving of fuel. There
are two engines on this plan Of 10 horse power,
low pressure, and one of so horse power, high
pressure, besldess small model sent to England
fot enhibltion at the Worlds Fair.
These machines have been visited by many
capitalists and others during the past week, and

ments to place his engine 10 large ship for tia

The third plan is that of the Static Pressure En-.
gins of Messrs. Sawyer and Gwynne, in which the
compression OF atmospheric air is proposed to be
made effective by the introduction OF centrifugal
force as auxiliary agent power the initial moving
loce, or atmospheric pressure, and the auxiliary
force, both acting elastic fluid or water which
Is used as the medium Of notion In the two first
arrangements, it is claimed that power can be ma-
tanned at much cheaper rate than heretofore, and

any extent may be maintained, free of all cost bepond

lucuhration. The two first are in operation; the
last named is yet to be made go-the construction
OF working engine being now rapidly urged to
completion.
