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. [For the Scientific American.]

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
