Philosophical Bellows

There be here set down three figures of these kinds of instruments which belong to several uses.

A. Signifies that which blows a fire for the melting of any metal or such like operation, and it blows most forcibly with a terrible noise.

B. That which blows a candle to make the flame thereof very strong for the melting of glasses and nipping them up.

C. That which anyone may hold in their hand to blow up the fire strongly upon any occasion. Now the manner of the using of them is this. You must first heat them very hot. Then put the noses thereof (which must have a very small hole in them, no bigger than that a pin's head may go in) into a vessel of cold water. They will presently suck in the water, of which then being full, turn the noses thereof towards the candle or fire which you would have blown.

As for the figure C, it must have a mouth drawn up around and hanging out an inch from the face, which mouth (the whole compass of the face being heated first) you must dip in cold water, and it will suck in water as the noses of the former did. This then you must hold close to the fire that it may be heated, and it will blow exceedingly, as otherwise it will not, viz., if it be cold. If you put sweet water into such a vessel, you may perfume a chamber exceedingly, for a little quantity thereof will be a long time breathing forth.

Note that these kinds of vessels must be made of copper and be exceedingly well closed so that they may have no vent but by their noses.
