found that the same phenomenon was produced, the platinum was heated to [[strikeover]] [??]] [[/strikeover]] a white heat nearly.
The globule remained a few moments staling, or in motion with the gliding motion of the drop of water, and then suddenly disappeared with something like an explosive action.
6. Tried on the same piece of platinum small globules of melted lead and tin, but no effect like that produced by the mercury and water was observed. The substance was incapable of giving off a vapour.
7 Small drops of water were thrown on to a small cup formed of thin plate platinum, heated to whiteness in the spirit lamp. The water remained some minutes un evaporated, slowly however diminishing in bulk, and when it got to the size of about that of a pin's head, it disappeared at once with a kind of an explosion & sometimes an explosion took place which seperated the small dish into two parts. _ all the time ^[[the]] drop was diminishing, the little cup of platinum which contained it, was at a low red heat, but the moment that the drop disappeared, the metal became white hot. This shows the constant evaporation which is going on.

flame of a spirit lamp, the drop does not instantaneously disappear, but it remains several minutes and gradually disappears. It would appear from these experiments, that the slow evaporation of a drop of water on heated metal is due to the [[underlined]] constant[[/underlined]] generation as the lower surface of the drop of a quantity of steam, which by its elastic force, prevents the drop from coming [[black crossed out]] in contact with the heated metal. The heat necessary for the constant production of the steam, is conveyed to the water by eradiation from the heated metal.

Also it would appear that in order to the sudden evaporation which produces the phenomenon called boiling, it appears necessary that the water should be in physical contact with the metal, and if this be correct, boiling will not take place at the same temperature in vessels which are not capable of being infilmed with the liquid. Hence, I should infer that mercury will boil in a vessel of which the inner surface is amalgamated ^[[sooner]] than in one of glass, which has no attraction or little, for the metal.

There are blue notes in this that alter/clarify some words. 08-22-14-BW I believe "evapora-tion" at the end of left-hand page, 5th line from bottom is hyphenated.
