60 SCIOPTICON MANUAL. fish, up and down is a matter of indifference; so that inversion is no disadvantage. "With this tank for the exhibition of living objects, chemical reactions, &c., a large assortment of slides is less of a necessity. PRECAUTIONS ABOUT The lantern exhibition has to be conducted in so ob- scure a light that the operator has to depend more on the sense of feeling than sight; it is therefore important that the slides should be in good condition and properly arranged beforehand, and that their titles and descrip- tions should be well fixed in memory, A convenient box for carrying the slides, for arrang- ing them in, and for showing them from, is constructed as follows.' Two boxes of any desirable length, 7J inches wide and 4| inches deep, are hinged together, so that each serves as a cover to the other. This double box will hold the ordinary wooden mounted slides without waste of room, and when open will show their labelled edges in proper position and order. In social gatherings, the exhibitor is often urged to bring out certain favorite pictures on call, which, in the hurry and darkness, is apt to disarrange the slides, so as to perplex the operator, and mar the beauty of the entertainment. With careful management the box may close on prop- erly arranged slides, at the close of the exhibition.
