Publisher's Synopsis
Excerpt from Scientific Amusements
Hydrostatics, the study of the effects of ?uids, supplies many interesting facts and illustrations to this little book. The ascent of wine in an inverted glass of water, the ?oating 'of a needle, and the lobster 'syphon, are among these. The maintenance of various bodies in the air by currents of air, and the phenomena of vortex rings of smoke, are equally striking and instructive. Various experiments on the pressure of the air and with com pressed air, and the properties of air and gas balloons, complete the section dealing with pneumatics.
