An important meeting of the manufacturers of velocipedes was held in this city on Monday, the 7th inst. All parts of the country except New England were represented, and the action was unanimous. It was determined to resist all claims under the Lallemont and Smith patents, and to recognize the Hanlon patents alone. A fund for the purpose of the expected litigation will be provided by a contribution of from fifty cents to a dollar upon each machine made. A committee, to take charge of the future proceedings was appointed, consisting of Messrs. T. R. Pickering, Cornelius Van Horn, and G. H. Mercer; Mr. Van Horn as Treasurer. They will at once retain suitable counsel, and prepare for the contest. The newspapers from Amsterdam, the capital of the Netherlands, mention a new steam velocipede invented by a certain Mr. J. Loeff. It has three wheels, is compact, easily governed, runs very fast, and may be easily stopped. One has been made so as to accomodate two persons, having a steam engine of li-horse power, making about twenty miles an hour. Another is in course of construction, of 3-horse power, with seats for four persons. The success of.these vehicles is said to have been such that the practicability of using such velocipedes, instead of horses, to propel the boats on the Dutch canals, is under discussion. To carry out this plan, a company has already been formed. The French papers contain the description of a peculiar velocipede invented by M. Guillcrmin, of which we give an extract : It has three wheels, and is partially covered by the figure of a horse made of india rubber. In the sides of this horse is wheelwork driven by springs, made of thin steel strips,. thirty yards long, which are wound up as spirals. These sprin3 are so connected, by means of a series of cog wheels, with the wheels oftho velocipede, that, when once wound up, they cause these wheels to make two thousand revolutions, and as their diameter is 3 feet, they may run more than 3 miles when once wound up. The handle, with which to wind up, is at the side of the horse, within reach of the rider, who can turn it withoiit stopping the machine. The india-rubber horse has its fore legs on the axis of the front wheel; serving in fact only as envelopes for covering the legs of the rider, who apparently makes no motion, but he uses his feet and hands for steering and propelling. It is expected that one may make 15 miles per hour with this machine without fatigue. The ears of the horse are handles by which the rider opens the head, in wliich is a box containing provisions and refreshments; wliile behind him, another receptacle in the horse contains bis valise and other property. It is reported that Frenchmen regard this ridiculous machine as one of the most elegant things wliich has yet appeared since the velocipede sensation first commenced. Titusville Pa About a mile below Titusville, the first oil-well derrick that was ever built, in this or any other country, is still to be seen. In the light which petroleum has thrown upon the world since, the history of this primitive enterprise stands out like a romance, the interest of which is hightened not a little by the fact that the man who first bored for oil, and by his pluck and perseverance, not only flooded a community with sudden riches, but increased the wealth of tho world, is to-day himself a poor man. That man is Mr. E. L. Drake, commonly called " Colonel Drake " in the oil region. He first made his appearance here in 1857. Previous to that time he had been a conductor on a railroad in Connecticut. Before the first oil well was sunk Titusville (named after a family of Tituses) was a small backwoods village, with a population of raftsmen and lumbermen numbering about two hundred. Oil flowed from that well, and in five years Titusville became the fourth post-office town in the State. It had forty hotels, and a fixed or floating population of I know not how many thousandsspeculators, shop-keepers, well-diggers, and teamsters. The army of teamsters alone numbered at one time not less than four thousand. Very different is Titusville, to-day.The brick blocks that Sprang up in that period of excitenient Btill remain j and I am told that Jt Km. now. jwmmneiit population of mfea thoa sand. But comparative quiet reigns hero. The forty hotels have been reduced to four or five. This change has not been brought about simply by the failure of wells in this vicinity and the continuation of the railroad down the creek. Oil enough still comes here to keep up the old excitement, if teams were any longer of use in conveying it. Teamsters supported the hotels, the shops, the smithies, and kept various branches of business alive; bat the time came for a revolution in this cumbersome and costly method of transportation. Teamsters were to be superseded. The right man stepped forward at the right moment, and spoke the word of common sensealways a danger and a menace to old routine. " Instead of all this clatter and hubbub of wagons and whips and oaths, in carrying loads of barrels over land, why not," said he, "send the oil silently flowing underground, through pipes, like so much Croton or Cochituate water?" There-form was of course opposedas all such reforms must be at the outsetby the class whose interests were assailed. Mobs of teamsters tore up the pipes, burned the tanks, and threatened the lives of the pipe-layers. This was done repeatedly; but it was striving against fate. In 1865 the system was fairly established, in spite of all opposition, and now almost the entire product of the oil region, amounting to ten thousand barrels a day, flows or is forced through pipes, from the scattered farms, to the railroad centers, and the army of teamsters has disappeared. A great saving in transportation, in whiskey, and profanity, has been the result.Atlantic MojdMy. Treatment of Scarlet Fever Dr. Charles T. Thompson reports in the Lancet his manner of treatment in scarlet fever as follows : The patient is immersed in a warm bath in the early stage of the disease, and this is repeated frequently, or as oiten as the strength of the patient will allow. The first effect is to produce a soothing and refreshing feeling in the patient, to be followed soon by such an eruption on the surface, of so vivid a color, and in such amount as would astonish those who have never witnessed it. Thus one of the greatest dangers of this fearful diseasethe suppression of the eruptionis escaped. The appetite generally returns after the first or second bath, and the strength of the patient is kept up by nutritious food. The bath prevents the dissemination of the disease, by removing the excreta from the skin as soon as it is deposited. This treatment promotes cuticular desquamation. The body should be gently dried by soft linen cloths after the bath. By this procedure the various secretions are deprived of their noxious properties, and the irritation of internal organs is quickly relieved, thus dissipating infection. Another benefit is that a very serious case is soon reduced to a mild one, and the patient recovers in less than half the usual time. Since Dr. Thompson has pursued this practiceduring the last fifteen yearshe has never lost a patient from scarlet fever.
