presiding there, onght to be called, with respect to American

inventions, «а permanent committee of rejection». At this very

time ат still waiting for ап answer to some highly impor-

tant original contrivances, which have forwarded six and

nine months ago—so much for encouragement and patronage of

american inventions!

proceed now to уоиг simple and beautiful application, as

уои justly observe, of «the laws of Nature» to the produc-

tion of heat. ат concerned to inform уои, that the locomo-

tive engines employed here оп rail roads, and count kumford

of 300 dollars in а cnse, where, from the anticipation already

alluded to, the commissioners тау not grant patent at all, ог

the patent itself, if granted, promises по solid advantage what-

ever. conclude this subject by acknowledging ту utter

ignorance of the russian patent laws, and the grateful fee-

that is essential in them, and necessary for те to know. I ат
