Such things as test-tubes should be found in every photographer's work room; they cost little, and are always useful for working solutions. The sizes recommended are3/8-inch,1/2-inch, and 1-inch diameter. A dozen of each will not be out of the way.
and
With the former we have this action—
With the latter the silver in combination with the organic matter, which is in a state of oxide, is probably reduced to the state of sub-oxide.
Sulphuretted hydrogen may be prepared by pouring dilute sulphuric acid on ferric sulphide. The chloride or the silver compound, when damped, may be held over it, taking care that no liquid is spirted up on to it.
Those who prepare collodio-albumen plates will find the upward filtration arrangement of immense value, as bubbles are unknown by it.

Hydrofluoric acid is always supplied by chemists in gutta-percha bottles, as it attacks glass. A spare gutta-percha bottle can easily be procured.
This calculation is near enough for our purpose. There are certain niceties which might be introduced, such as the "critical angle of the glass."
The boxes in which children's puzzles are often packed will give an idea of what is meant.

Or ten minims of ammonium lactate.
