MESSRS. EDITORS—In No. 23 of the present volume of the SCIENTIFIC AMERICAN will be found an account of an ostensibly new invention, recently patented in Great Britain, by which glass bottles are made with female screws in their noses, necks or mouths. If you will refer to the List of Claims published in No. 49 of Vol. X of the SCIENTIFIC AMERICAN, (August 18, 1855,) you will see that Amasa Stone, of Philadelphia, Pa., patented a tool for forming a screw in the nose or neck of a bottle; and this must be the same thing as the English device described in the Illustrated Inventor. Mr. Stone's tool has been in use in this country ever since the date of the patent; and I will warrant that all bottles made thereby will tightly hold their corks. If any of your readers want bottles made in that fashion, or a tool for making them, I can tell them where they may obtain either on very reasonable terms. I send you this merely to assure you that " Old England" is by no means ahead of " Young America" in respect to bottle-noses. A SUBSCRIBER. Philadelphia, Pa., March, 1858.
