ENGINEERS and draughtsmen generally keep note-books in which are jotted down most things they wish to particularly remember, accompanied by rough sketches when necessary. The author of this book is no exception to the rule. He tells us he has made many notes and sketches during his experience as an engineer, and has often found the want of such a collection for reference. This volume consists of about 1936 sketches, classified under different headings, of devices, appliances, and contrivances of mechanical movements. The book is certainly unique in its way, and will prove useful to those who have machinery to design, who may require suggestive sketches of mechanical combinations to accomplish some desired end. The author truly remarks that a sketch properly executed is to a practical man worth a folio of description. Hence the descriptions given are generally mere names, with occasionally a concise statement of purpose. Each sketch bears a number, and on the opposite page this number is to be found with the description, and &c.,—a very good arrangement.
