SCIENCE.

He claims, in his article, that the facts I used are his, while 

 in the preface to his book he lays no claim to the facts. Here 

 is what he says : ' 'The nature of the work is such that I have no 

 claim for the presentation of new material." In regard to 

 "Rocks and Soils, " published by Dr. Stockbridge, I have lately 

 examined it, and I can confirm what he has said, that it does 

 not contain a single fact new to science. I believe one such 

 claim is made, but the /acts have been in print tot forty years. 

 We have the same publisher, and for that reason I do not care to 

 make any comments upon it. Any of your readers that are in- 

 terested will find a review of it in Nature, Jan. 24, 1889, p. 392.

INDUSTRIAL NOTES. 

 The Electric Light in Japan. 

 An American electric-light system has again come out victori- 

 ously while competing with the older European systems. This 

 time the battle-ground was Tokio, Japan, where a corporation of 

 capitalists, The Takata Company, awarded a large contract for 

 electi-ic lighting to the Westinghouse Electric Company of Pitts- 

 burgh, Perm. The Westinghouse alternating-current system has 

 gained great favor in eastern Asia, as an immense central station 

 for electric lighting is now being installed with Westinghouse 

 alternating-current apparatus in Canton, China. The Japanese 

 plant will be put up at Shidznoka, near Tokio, and it will have 

 a total capacity of 500 lights. This is the first alternating-cur- 

 rent central-station plant in the land of the Mikado. 



A Big Road goes in for Electricity. 



During the last week Mr. Thomas Lowry, president of one 

 of the largest street-railway combinations in the world, showed 

 his confidence in the electric system of street-railway propul- 

 sion by deciding to equip all the lines of St. Paul and Minne- 

 apolis by electricity. The electric company to whom this con- 

 tract was awarded is the Sprague Electric Railway and Motor 

 Company, and the investment called for from the street-railway 

 company is said to be in the neighborhood of two million 

 dollars. 



Before deciding upon any system to be used upon these roads, 

 the president of the company, together with the directors, 

 made a careful inspection of all the difi'erent methods of 

 operating street-cars in large cities, and investigated the merits 

 of each. As a result of this investigation, the contracts for 



the partial equipments of the road by cable were cancelled, and 

 negotiations were entered into with the Sprague Company for 

 the entire electrical equipment. 



By the terms of the contract, the Sprague Company is to 

 fully equip and put into working order the entire mileage 

 owned by the railway company, the work to be completed by 

 June 1; and the first delivery of electric-railway apparatus, 

 which will include 360 Sprague improved motors for the equip- 

 ment of the rolling-stock, will be made shortly. 



This is pi'obably the largest order which has ever been given 

 for electric-railway motors, and evinces the confidence which 

 prominent street-railway managers feel in the electric system. 



Photography done Quickly. 



The initial letters of the above three words have been adopted 

 as the name of the "P. D. Q." camera, a new detective 

 camera of small size, manufactured by E. & H. T. Anthony of 

 this city. This camera, which is shown in the cut, is adapted 

 to the making of four-by-five inch pictures, either time or

instantaneous, and which may be taken either vertically or 

 horizontally. It is provided with a finder which may be used 

 for either position. Three patent .double holders are supplied 

 with each camera, — one for dry plates and two for films. The 

 double-film holders are very durable and compact, being only 

 three-eighths of an inch thick. 



This camera is fitted with a combination instantaneous 

 achromatic landscape lens and a shutter of a new design, which 

 by its peculiar mechanism is always closed except at the 

 moment of exposure, the resetting being accomplished by an 

 ingenious device, which requires only the movement of a lever 

 to the right or left. The manipulation of the shutter is wholly 

 from the outside of the box, and it may be made to work v^ith 

 greater or less rapidity, as desired.

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists ofEurope and America, and bringing them 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indifiestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of "one remedy for one 

 disease " must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bottle, and the use of which, as statistics prove. 

 has I idned more stomachs than alcohol. A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors.
