About this book
The instructions for a blow-pipe explain how occasional strokes of a pump maintain the blast as consumption of the fluid reduces pressure. The burner directions describe heating the burner and checking whether liquid or spray comes from its orifice as a test of sufficient heat.
The discussion of wheel teeth explains that the epicycloid can be approximated in horology and used with pinion leaves having straight faces. The treatment of wax warns that some kinds are too dry and others too soft, requiring a series of trials to establish the material's efficiency. Some workers are reported to claim good results from a mixture of sealing-wax and shellac.
