“ The condenser is easily detached from its "fittings," and its application to the camera would be as simple as that of an ordinary object-glass.
However, my conviction remains that, in spite of all that perseverance and science can accomplish, it never will be in the power of the photographer to produce a picture of an object under the microscope, equally distinct in all its parts; and unless his art can effect this, I need scarcely say that his best productions can be but useful auxiliaries to the draughtsman.

“ Genuine amber, when rubbed together, emits a very fragrant odour similar to a fresh lemon, and does not abrade the surface. The fictitious amber, on the contrary, breaks or becomes rough, and has a resinous turpentine-like smell. Genuine amber is to be obtained generally of the tobacconists, who have often broken mouth-pieces by them: old necklaces, now out of use, are sold at a very moderate price by the jewellers. The amber of commerce, used in varnish-making, contains so much impurity that the waste of chloroform renders it very undesirable to use. ”
