provided with a society screw, and consequently will fit any adapter 
intended for using an objective as an achromatic condenser. ‘The 
iris is worked by a milled collar, corresponding to an adjustment 
collar of an objective. 
In SIDLE’s “‘ ACME” STANDS all the stages rotate, are furnished 
with a means of centering by lift and press screws, and are pro- 
vided with stop for Maltwood finder and socket for stage forceps. 
The stages are thin, admitting the use of very oblique light. For 
illumination of still greater obliquity, the stage may be turned 
over, so as to have the object slide on the lower side of the stage. 
The fitting on which the stage reverses is divided into single 
degrees, for twenty degrees upon either side of the horizontal, for 
experiments in the resolution of lined objects. This is accom- 
plished without throwing the object out of centre of the swinging 
sub-stage. The stage ring or bed-plate is furnished with a spring 
clip arrangement, which admits of the easy interchange of the 
mechanical and plain stages and insures a smooth motion in 
rotation. 
THE FILMOGRAPH.—Mr, Pumphrey, of Birmingham, is issuing 
rapid gelatine films, intended to supersede the ordinary gelatine 
plates now so largely used in photography. We have seen pictures 
produced by them, which are in all respects satisfactory, and we 
notice them here, thinking they may be possibly applied to the 
production of transparencies for the lantern. If such could be 
done, they would be very convenient for lecturers, as a dozen 
films, 84 by 63, weigh but three ounces, or one-twentieth of the 
weight of glass. 
The mode of manipulating these films is given with each packet, 
and differs but little from the ordinary method for gelatine plates. 
THE LATE CHARLES Darwin.—Westminster Abbey, as was 
fitting, was chosen as the last resting-place of Charles Darwin. 
The pall-bearers were the Duke of Argyll, the Duke of Devon- 
shire, the Earl of Derby, Sir Joseph Hooker, the American 
Minister (Mr. Russell Lowell), Dr. Spottiswoode, President of the 
Royal Society, Professor Huxley, Mr. Alfred Russell Wallace, 
Canon Farrar, Sir John Lubbock, M.P., and there was an 
immense and representative gathering of all sections of society. 
The grave is nearly in the centre of the nave, slightly to the left 
of the entrance to the choir, and in the organ gallery, and imme- 
diately against the grave of Sir Isaac Newton. An anthem com- 
posed for the occasion by Dr. Bridge was sung to the words from 
the Book of Proverbs, “ Happy is the man that findeth wisdom, 
and getteth understanding. She is more precious than rubies, 
and all the things thou canst desire are not to be compared unto 
her. Length of days is in her right hand, and in her left hand
