ERIcssoN's ENGINE is to be introduced in a
printing Office. The New York Evening Post of
the 2sth ultimo says:
A friend from Ohio who has seen the articles in
the EDen,ng Post upon the subject of Ericsson's
Calorc Engine alludes to the subject as follows in
the course of a recent letter:

The strength of our faith may be Judged from
the fact that we have contracted with Captain
Ericsson to furnish US with a caloric engine as
soon as it can be made, for the use of the Evening
fost, and 1t Is already in state of considerable
lorWardness. Inc patterns are prepared by Cap
tain Ericsson, and the machinery is making by
Messrs Hogg and DeIamater. 1t is to have suffi-

We also anticipate substantial advantages from
the greater simplicity of the machinery, which
will render fewer repairs necessary; from the
greater durability of the combination, and from
