INDUSTRIAL NOTES. 

 New Portable Photometer. 

 To meet the demand created by the rapid adoption of the elec- 

 tric light for town and city lighting, and consequent necessity of 

 making frequent tests for the purpose of conforming to certain 

 standard conditions, Messrs. Queen & Co. have recently brought 

 out a new form of Bunsen's photometer. This instrument is de- 

 signed especially for street "work, and will be found invaluable to 

 municipal and government inspectors and experts having occasion 

 to make candle-power tests of arc and incandescent lamps. The 

 photometer is 5J inches square in cross-sections, and 38 inches in 

 length. The lantern, as shown in the cut, slips into one end of 

 the box, where it is firmly held. A small adjustable holder car- 

 ries the standard light, which may be either one or two standard 

 candles. This adjustment regulates the height at which the 

 flame stands, and also its distance from the screen. By making 

 this latter distance exactly one foot, computation is greatly facili- 

 tated. Distances are measured by a graduated bar which slides 

 in grooves along the side of the box. To allow for the difference 

 in vision between the right and the left eye, the instrument is 

 made reversible; i.e., it may be turned completely over, so that 

 the right eye observes the side of the disk before observed by the 

 left, and vice versa. When not in use, the lantern-chimney slips 

 out, and can be placed inside the lantern itself, after which the 

 entire lantern-box may be pushed inside the photometer, and 

 small slides made to cover the two ends and the sight hole of the 



instrument, making a solid box of it. A brass handle on one side 

 allows the instrument to be carried as easily as a small hand-bag. 



QUEEN'S NEW PHOTOMETBK. 



If desirable, a small incandescent lamp may be used as a standard 

 instead of the candles. The range of the instrument is from 

 about four candle power up.

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 of Europe and America, and bringing them 

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

 ment pursued by special physicians who treat 

 indieestion, 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 rtdned 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.
