APPARATUS FOR MANUFACTURING GASEOUS OR AERATED BEVERAGES. The apparatus employed at present for making gaseous beverages are divided into two classes—intermittent apparatus based on chemical compression, and continuous ones based on mechanical compression. The first are simple in appearance and occupy small space, but their use is attended with too great inconveniences and losses to allow them to be... more...

LOCOMOTIVE FOR ST. GOTHARD RAILWAY. We give engravings of one of a type of eight-coupled locomotives constructed for service on the St. Gothard Railway by Herr T.A. Maffei, of Munich. As will be seen from our illustrations, the engine has outside cylinders, these being 20.48 in. in diameter, with 24 in. stroke, and as the diameter of the coupled wheels is 3 ft. 10 in., the tractive force which the... more...

THE RAPHAEL CELEBRATION AT ROME. The most famous of Italian painters, Raffaele Sanzio, whom the world commonly calls Raphael, was born at Urbino, in Umbria, part of the Papal States, four hundred years ago.

FARCOT'S IMPROVED WOOLF COMPOUND ENGINE. In a preceding article, we have described a ventilator which is in use at the Decazeville coal mines, and which is capable of furnishing, per second, 20 cubic meters of air whose pressure must be able to vary between 30 and 80 millimeters. In order to actuate such an apparatus, it was necessary to have a motor that was possessed of great elasticity, and... more...

IMPROVED DYNAMO MACHINE. The continuous current and the alternating current generators invented by Dr. J. Hopkinson and Dr. Alexander Muirhead are peculiarly interesting as being probably the first in which the bobbins of the armature were wound with copper ribbon and arranged on a disk armature much in the same way as was afterward done by Sir William Thomson and by Mr. Ferranti. In the... more...

In my presidential address, which I had the pleasure of reading before this society at our first meeting this year, I called attention, somewhat hurriedly, to the results of a few of my experiments on induction, and at the same time expressed a hope that at a future date I might be able to bring them more prominently before you. That date has now arrived, and my endeavor this evening will be to... more...

FARCOT'S SIX HORSE POWER STEAM ENGINE. This horizontal steam engine, recently constructed by Mr. E. D. Farcot for actuating a Cance dynamo-electric machine, consists of a cast iron bed frame, A, upon which are mounted all the parts. The two jacketed, cylinders, B and C, of different diameters, each contains a simple-acting piston. The two pistons are connected by one rod in common, which is fixed... more...

THE DODDER. The genus Cuscuta contains quite a number of species which go under the common name of dodder, and which have the peculiarily of living as parasites upon other plants. Their habits are unfortunately too well known to cultivators, who justly dread their incursions among cultivated plants like flax, hops, etc. All parasitic plants, or at least the majority of them, have one character in... more...
