MODELS OR SPECIMENS OF Inventions may be sent to the Polytechnic Institution, PARTICIPATION IN INVENTIONS (A Master Manufacturer).-If the workman was merely employed to work out his master's ideas, and invented nothing himself, he has no claim in law or equity to any share of the proposed patent. DISCLAIMERS are not all advertised. The law officers of the Crown may do as they please in this respect. TREVETHICK is still without any monument to his memory—the more the shame. He lies buried in Dartford churchyard. DisCOVERY OF THE LONGITUDE.-P. V. has won. There is no longer any reward offered by Government in relation to the discovery of the longitude. The truth is, that the skill and ingenuity of our chronometer-makers have left nothing to be discovered. THE GOVERNMENT School of Design teaches drawing only, and as long as it does 80, will never turn out a good practical designer of soft goods patterns. “ D. S." should send his son to some of the Manchester or Glasgow print-works. Designs REGISTRABLE UNDER THE New Act.-(A Designer.) The New Act strictly confines the privilege of registration to ornamental designs. Fictitious USE OF THE TERM “ Patent." There is no statutory penalty; the only objection is, that the thing is dishonest, and would probably be held to be a fraud by the common law of the land. PERPETUAL MOTION. The following brief extract from the illustrious Smeaton, may perhaps suffice for an answer to “ Experimentalist.” “We want (for perpetual motion) bodies having the following properties : that when they are made to ascend against gravitation, their absolute weight shall be less ; and when they descend by gravitation through an equal space, their absolute weight shall be greater, which, according to all we know of nature, is a repugnant or contradictory idea.” Just published, price 6d.
