A Handbook of Laboratory Glass-Blowing
by Bernard D. BolasTo cover the whole field of glass-blowing in a small handbook would be impossible.

The Biology, Physiology and Sociology of Reproduction

He notes the germination of the plant seed and its early growth, step by step approaching a stage of maturity; it blossoms, produces seed, and if it is an annual..
