T is supposed that the Magic Lantern originated early in the 13th century, I when it was employed to excite the awe and credulity of the public so-called by magicians. This continued to be its prin- cipal use until within the last thirty years. Whereas, formerly, those skilled in arts and sciences sought craftily to preserve their knowledge a secret, except from a chosen few, it is a characteristic of the present age that the man of science seeks to share the result of his labors with his fellow man. The Magic Lantern has been modified, improved and re-named so that the stereopticon of today bears little resemblance to the crude instrument which excited the wonder of the ignorant and enabled the unscrupulous to play upon their superstitious fears in the ages that have passed away. The scientific investigator, the educator, the lecturer and he who simply caters to the higher amusement of the public, find in the stereopticon an indispensable aid. In its improved form most delicate investigations into chemical, physical, electrical and pathological phenomena are possible; and what is of most importance, the method of conducting such research, and its immediate results can be shown to an audience as easily as to a single individual. The educator can illus- the trate in most effective manner by its aid, Physiology, Botany, Natural History, Chemistry, etc. Problems can be demonstrated^ lessons drawing given, maps, diagrams, formulas and a great variety of exercises suitable for the class room can be displayed in a way to impress them upon the memory more firmly than by the older methods. Those who have made use of the Solar Microscope and Stereopticon largely for purposes instruction of are enthusiastic in its praise. Literary Colleges use it. A gentleman at the head of one of the largest institutions in the country where a stereopticon is con- stantly used, writes thus: “After the Stereopticon, the Black- board seems almost good for nothing. I wonder how we have managed so long without it.’’ Medical Colleges. We have supplied many medical colleges with a complete outfit for using the Microscope and Stereopticon with Solar and Artificial light. This method of illustrating medical lectures is very popular with the students, and insures full seats during the hours when this apparatus is employed. 2 MCINTOSH BATTERY AND OPTICAL CO., CHICAGO, ILL., U. S. A. Microscopists find frequent use for the solar and oxy-hydrogen light, especially when spending many hours daily in original inves- tigation. It enables them to study many processes on a larger field, giving the relation of parts, and economizes time, aside from the con- venience of being able to demonstrate to all observers the work done. Lecturers, whether engaged in instructing the public through the medium of lectures on natural science, or furnishing intellectual amusement suited to a promiscuous audience, thoroughly appreciate the benefits accruing from the use of the Stereopticon with a suitable selection of slides. The public never tires of good pictures and now that the art of photography has developed methods by which the amateur can easily learn to make his own lantern transparencies, a good Stereopticon is a most profitable investment for those who are engaged before the public. Sunday Schools may not only be amused and interested, but religious instruction may be impressed upon the hearts of young and old in a most effective manner by a Stereopticon in the hands of a judicious Pastor or Superintendent. The illustrated Sacred Hymns, especially, form the most touching and beautiful exercise that can be imagined. Some of our leading Pastors use this instrument constantly to illustrate the Sunday School Lessons. Temperance Societies find in the Stereopticon an invaluable aid in exciting interest in this subject which so large a proportion of the public regard as hackneyed and tedious. So extensively is this realized abroad that the most exquisite and varied lecture sets bearing on Temperance have been prepared, many of which have never been introduced into this country. Bands of Hope, Juvenile Humane Societies, etc., which are designed for the benefit of children need every resource for im- parting amusement and instruction, judiciously intermingled to keep up the interest of their members. In the Stereopticon they possess the very elements needed for this purpose. Lodges, Granges, Grand Army Posts and all other Societies of a similar character, make considerable use of the Stereopticon as an attractive and economical means of illustrating their rituals or con- tributing to the interest of their entertainments. Insane Asylums and other Public Institutions where those mentally or physically enfeebled are cared for, find the Stereopticon of the patients can be directed an endless source of interest ; the minds pictures. to any subject thought desirable, by properly selected Parlor Entertainment. The Sciopticon affords a never failing well source of amusement in the family. Impromptu exhibitions are MCINTOSH BATTERY AND OPTICAL CO., CHICAGO, ILL., U. S. A. 3 adapted to while away the long dreary evenings in stormy weather when people are so apt to find time hang heavily on their hands. The young people can receive valuable help in forming a refined taste for art by the exercise of care on the part of the older mem- bers of the family, in the selection of slides. The Sciopticon has not been so generally introduced into the family in this country as in Europe. The cheap and worthless instruments offered for parlor enter- tainments have caused dissatisfaction and have been cast aside. As soon as the public, generally, becomes aware that a cheap and satisfac tory apparatus is manufactured, there is no question but that this form of home entertainment will be more generally appreciated. Many ladies who have become expert in amateur photography entertain their ” friends at home with the products of their “ summer outing in the form of views which they have taken of the objects and places of interest discovered in their trip. These can be so readily transformed into beautiful lantern transparencies that this art has become a fascinat- ing recreation to those willing to take the trouble to acquire the simple but necessary details of the process which will be found described in this catalogue. Advertising Stereopticons have become a popular method of bringing advertisers to the attention of the public. Properly managed, this is lucrative both to the exhibitor and his patrons.
