What reading level is School And Industrial Hygiene book?
To quickly assess the difficulty of the text, read a short excerpt:
The affection here described is not confined, how- ever, to writers, but affects also pianists, violinists, engravers, seamstresses, telegraph-operators, tailors, type-setters, and many other classes who use one set of muscles almost exclusively.
The theory has been put forward that writer's cramp is caused by an electric current generated in a metallic pen, or by the contact of pen and holder. This can- not be admitted. The disease is fundamentally the same, whether caused by work with the pen... or on catgut or ivory. But a steel-pen may be found inju- rious, and can be replaced by gold or quill ; or a large pen-holder may be used, made of cork, of the size and shape of a large cigar, which is felt by many to be a great comfort in writing. A departure from the prescribed mode of holding the pen, and placing it between the forefinger and the middle finger, may also be a relief. Dr. Frank Woodbury, of Philadel- I I3O- SCHOOL AND INDUSTRIAL HYGIENE.
phia, has lately invented an ingenious pen-holder to prevent writer's cramp, by regulating the pressure at which the pen is used by a slight spring.
