F.R. B., of N. Y.-We have carefully examined the sketch and description of your alleged improvement in rotary engines; it possesses features entirely novel to us, having never seen anything nearer to it than Furman's, illustrated in pnr last volume. We do not perceive a single advantage to be gained by it over many others, and we incline to the opinion that it will prove on trial a total failure; successful experiments will only satisfy us to the contrary. T. N. J., of N. H.You would see in our lastnum- ber something more upon anastatic printing. We are not at present in possession of any more information upon the subject; but we shall endeavor to present it when obtained. N. O. L., of N. H.Your proposition in regard to warming shops from the fire of a smith forge, requires to be more specifically explained before we can advise respecting it. S. F., of PaWe do not remember -ever to have seen a car brake constructed like yours, and think it patentable; you had better send us a model of it that we may more thoroughly understand its operation. You are too late to compete for Ray's premium. S. B. M., of Pa.There is nothing new in your Sausage Stuffer ; we have seen the same machine before. J. S. H., of Ill.Minifie's Drawing Book is being issued in numbers; it is, we believe, the same as the original work. It requires a lens of sufficient power to take in the distance. W. D. M., of N, J.We do not know of a single good book on the subject you speak of. A. M. G., of S. C.The invention noticed in No. 6 of our paper is quite different frem yours; Mr. Gardiner's is of older date. Perhaps you had better send us a small model of yours and we will advise you more definitely. E.K. Purdy, Schoolcraft, Mich., wishes to know the price of a machine suitable for cutting walnut veneers. W. D., of Vt.By addressing Messrs. Fowlers &Wells. this city, they will furnish you with Phonographic works. . V. E. R., of Ill.For the fine list of subscribers furnished by you, accept our thanks. M. F., of Va.Every concern like the Collin's Axe Co. have secrets of their own for tempering; in some of the back volumes of the Scientific American you will find reliable receipts and hints upon the subject of tempering edged tools. G.G. H., of Pa.Paddle wheels constructed upon the plan you described are old and well known. H.J. T., ofBostonWe believe a patent for your application! ccraTd not be obtained.f"" O. H., of Ill.Your engine will operate, and for a very high fall and a small quantity of water, it will do Well, but you must expect no more from it than the gravity and velocity of the waterthe height is an index of the velocity. A number of water engines have been employed; we published one in Vol . 3 ; it is not so simple as the case water wheel, which we prefer. A. B. R., ofPa.Your plan is new, but you cannot obtain any valuable results. You never can obtain a power to drive an engine by a force of its own creation. See the opinion of Prof. Henry, in Vol. 6 . Sci. Am., expressed about the Paine Light, which was to do the same thing that you propose to accomplish. F.S. B., of AlbanyIf your volumes were complete there would be no difficulty in disposing of them, but as they are not we could not probably sell them for you at high prices. N. K. L , of N. Y.The atmosphere is allowed to be about 52 miles in height, and the pressure is 15 lbs on the square inch. H. P., of N. Y.If you will send yo';)r model to our office we will examine it and report upon the merits of your plan. We are suspicious, however, that you have got nothing new. G.M. P., of Mass.Mr. Green refuses to supply copies of his late Book of Specimen Types to any but those who are purchasers of materials. J. A. C., of N. Y.There is nothing new in the Churn which you describe; air has been introduced into churns in the same manner. S. G. B., of Wis.The mere application of boiler- iron to the bottom of a dirt scraper, instead efwood could not be patented; besides, scrapers have often been made in the same manner. W. C., of Canada WestYou will be able to obtain the Magic Lantern Reflector of Benj. Pike, Jr., of this city; we will hand your letterto him for attention. O. B., of Ind.We have seenwashing machines essentially similar to yours; we therefore conclude that you cannot obtain a patent.
