Let there be an altar having a pipe comming out of it, and entring the body of a hollow ball, let there come out of the same ball a crane, whose lower end make to hang ouer a bucket fastned to a rope, and hanging ouer a pulley, of which rope the other end must bee wound about two spindles, hauing two doores fastned unto them, and at the end of the same rope let there bee a waight fastned. So the fire on the altar will cause the water to distill out of the ball into the bucket, which when by reason of the water it is become heuier then the weight, it will draw it up, and so open the said gates or little doores.
Experiments of motions by rarifying ayre by fire.
Let there be a round vessell of glasse, or horn, and on the top of it a vessell of brasse, and in the midst a hollow pipe spreading it selfe into foure seuerall branches at the bottom: the ends of two of the branches must turn up, the ends also of two must turn down; upon these foure branches fasten a light cord, with seuerall images set upon it. Rarifie the ayre then by laying a red-hot iron upon the top of the brasse or tin vessell, and it will turn the wheele about, so that you would think the images to bee living creatures.
Another way.
First prepare a round peece of wood, hauing a brasse box in the midst, such as they make to hang the mariners compasse with, but a good deale bigger, round about this peece of wood fasten divers shreds of thin lattin, standing obliquely or ascew, as the figure doth represent; round about these fasten a coffin of thin pastbord, cut into seuerall formes of fishes, birds, beasts, or what you please. Prepare a lantern with oyled parchment, sufficient to conteine it, in the midst of whose bottom must bee erected a spindle with a narrow point, to hang the pastbord cut into formes upon: upon each side let there be a socket for to set a candle in, also let there bee made a doore in the bottom to put the candles in at, and after to be shut, and it is done. If you set two candles in the sockets, the heat of them will turne the whole pastbord of formes round.
