In the course of the past few years we must have saved, through our private correspondence, a mint of money to - would-be patentees. Some of the notions advanced are excellent, but imprac- ticable, others are simply ridiculous. As an indication of what is being done in this direction, we herewith produce alist of applications on patents filed in London for the month of November: Improvements in steam turbines. Improvements relating to ships’ compasses. _ Improvements in the propulsion of vessels. An improved fairlead bollard. Improvements in steam turbines, Improvements in receptacles for storing, releasing and distributing life-belts. Means or apparatus for recording the electrical vibrations or undulations known as Hertzian waves. Improvements in means for marine propulsion. The unsinkable boat with life-lines and buoys. The rescue, or saved by the life buoy. Improvements in steam generators for superheating the steam. Improvements in or relating to life-belts. Improvements in the means of carrying ships’ boats to facilitate launching them, and novel or improved means . to facilitate access to the boats when suspended ontboard.

We have now before us several ideas of incompetents who wish to patent, but, unless we understand, can learn, or ascertain that there is, or may be, merit in these, or any other propositions for patents brought before us, we are can- did enough to so state. or or LIEUTENANT Gontran de Faramond de Lafajole, naval attache of the French embassy, Washington, D. C., and M. Louis Revier, naval engineer, representing the French gov- ernment, have been in New York recently inspecting the Holland boat and it is announced that negotiations have been entered into between the representatives of the French gov- ernment and the company controlling the submarine torpedo boat for the construction of several vessels of the Holland type, aud also for the exclusive use of the patents for the submarine boat for the French government. A list of the requirements of the French government was given to a rep- resentative of the Holland company. Speaking of the boat, Lieutenant Faramond said: ‘‘Iam pleased with the boat. It is my intention to recommend that French experts in sub- marine navigation be sent here to study the Holland. I will also recommend that out of the appropriation now avail- able for submarine boats some of the Holland type be bought or manufactured. We want a great fleet of submarine boats and we want thebest. With vessels of this type our harbors would be made impregnable.’’ Tube Sheets, Centerboards, Fin Keels and Rudders, Tensile strength of plates one-quarter inch thick, upward of 78,000 Ibs, per square inch.
