Abstract

THIS book contains information necessary to the man who has what Dewar called “the use of his hands”, but who has not had workshop training, and is thus penalised in much loss of time and endeavour when setting himself to make and mend models, instruments and apparatus. Here also can one learn what materials are most serviceable,and how they are described, and where obtained; what are the most useful tools; and many suggestions, by the way, about the value of second hand oddments and out-of-the-way uses for common things; also valuable sections on glass-working and electrical wiring, with much more of the lore of an experienced laboratory assistant. All this is made plain by a large number of clear drawings, over which much labour must have been spent. On the other hand, of the two photo graphs comparing an attic workshop with one for a laboratory, uncertainty may be felt whether to admire the attic or be uneasy about the laboratory; partly no doubt because the detail available is insufficiently informing. Many examples have been included of actual constructions of demonstra tion apparatus and models.
