MCINTOSH BATTERY AND OPTICAL CO., CHICAGO, ILL., U. S. A. 71 Saturator is used every night. This can be done by unscrewing the caps that are numbered, and removing the cloth tubes and placing them out of doors, until the ether has evaporated and they are thoroughly dry ; then replace them in the Saturator. Fill the threads of the screws in the caps with common bar soap, and screw them on the tubes num- bered to correspond ; this makes them perfectly tight. If, when the oxygen key is closed to turn out the light, the lime continues to give out a bright light, even after the Saturator is turned on its side, it is an indication that the supply of ether is almost ex- hausted. This need not occur, because the Saturator will hold more than enough to supply a suitable proportion for an ordinary size bag of oxygen ; but if it does occur, the flame will give a harmless “ snap ” when turned out, or retreat into the Saturator, and blow off the rubber tubes, if the pressure of oxygen is insufficient. In the latter case the flame can be instantly smothered with a handkerchief or the hand, and no damage can be done. INDORSEMENTS. William A. Anthony, Professor of Phys- ics at Cornell University, was the first to test the new light carefully in comparison with the oxy-hydrogen. He used two “mixed gas” jets exactly alike, one sup- plied with ether from the patent Saturator made by the inventor, the other with hy- drogen from a gasometer. He says: “ With the same pressure of oxygen, the ether light is better than the hydrogen. * * In the qualities of steadiness, freedom from noise, etc., it is certainly equal to any lime-light, and in con- venience of manipulation, especially for travel- ing exhibition, it is far superior to either hydrogen or house gas.” The ether Saturator is just what I have been looking for for years. Having used it ever since you put it on the market, I have only words of praise for it. It is clean, safe, inexpensive and always ready for work. Although I have gas bags, cylinders, etc., for hydrogen, I never use them. The ether Saturator is far more convenient, gives a light equally as bright as hydrogen, and is perfectly free from danger of any kind. If now you can devise something that will take the place of the ordinary oxygen appliances, as the ether Saturator has taken that of hydrogen you will confer a great favor on all users of thv lantern. J. A. ZAHM, C. S. C., Pi'of. Physical Science, University of Notre Dame. I have used nearly, if not all, kinds of illumination for the lantern, coal oil, the electrical (arc) light, and all forms of the oxy-hydrogen or calcium light. For con- venience, safety, ease of manipulation and results, I prefer the oxygen and ether (Mc- Intosh-Ives Saturator) to all others. During the last year I was connected with the Woman’s Medical College, this light was constantly used, often by those who had no especial knowledge in manip- ulating the light, and no accident occurred, save, possibly, the blowing off of the tubes. PLYM. S. HAYES, A.M., M.D., Late Prof, of Chem. and Toxicology Woman's Med. Coll., and Prof. Analytical Chemistry, Chicago College of Pharmacy. My lantern pleases me very much. For projecting anatomical structures, both by photograph thereof and the specimen it- self, with microscope attachments, was sat- isfactory to myself and to the three hundred and more students and friends who attended our course of seven evening lectures, as per inclosed card. The ether Saturator, which I handled with some timidity at first, is no longer any source of anxiety, but ratner I have every con- fidence in it, and the light is elegant. For my work in the medical college as teacher of physiology and histology, I don’t want to ever cry to lecture without the lantern outfit. E. S. BAILEY, M. D., Registrar of Hahnemann Medical College Chi- cago, and Professor of Physiology and His- tology. Six years’ experience with your Stereop- ticon, with Microscope Attachment and the 1 res’ ether oxygen light, in illustrating my lectures on Diseases of the Nervous System, at the Woman’s Medical College, enables me to speak with some degree of authority about it. We use it at almost every lecture in the course, and we find it so simple in its construction, and so perfect in its action, that any person of ordinary capacity can, in a few minutes, learn to manipulate it successfully. We are confident that it ma- terially elucidates the complex subject we teach, affording us much satisfaction, and the students much profit. We lecture in the spring course in another college, in which a very much more ex- pensive apparatus, of English construction, is used, and we can say with emphasis that tl .** illumination and smoothness of work is rery much in favor of your excellent combination. We commend the apparatus to all teach- ers as furnishing the best and cheapest method of illustrating their work. I might say that such is the power of the light, that we can satisfactorily show our slides in a room light enough for easy note taking. D. R. BROWER, M. D., Prof. Diseases Nervous System in Woman’s Medical College , Chicago.
