10th Report of the Quekett Microscopical Club „ 
The Chairman thought it would be interesting to notice that they 
had before them for exhibition what he thought was the first practical 
Microscope yet made of aluminium. The great point about this instru- 
ment was of course its extreme lightness, the whole thing complete, 
including the condenser and eye-piece, only weighing 2 lb. 10 oz., as 
against the weight — 7 lb. 13 oz. — of a precisely similar one made in the 
usual way of brass, or about one-third of the weight. This was a matter 
which would of course strongly commend it to persons who were much 
in the habit of carrying their Microscopes about from place to place.
