Notes, In the course of some experiments with the electric search light, it has been ascertained that when the light has been projected upwards at an angle of 45° the reflection can be seen in the air at a distance of ninety miles. az * a A new set of 54 slides, which should be of particular interest to the public at large, has been published by Messrs. Archer & Sons, Lord Street, Liverpool. They represent “ Slum life.” aE At oe Tuat ether is capable of causing sad havoc when used in a careless manner, users of saturators are doubtless aware. About a fortnight ago a photographer in Paris dropped a jar of ‘collodion : his assistants immediately commenced to mop it up, but having omitted to open the windows, the fumes reached a stove in an adjoining room, and fired, with the result that the building took fire, and it was afterwards ascertained that two people lost their lives. * * * Opricians will no doubt be astonished when they see at work at the Chicago Exhibition a new invention, which will make lenses four hundred at a time. * bd = Tue Manchester Photographic Society make it arule that at their open lantern meetings, no one member is allowed to exhibit more than 18 slides.
