We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Fig. 8 — Mechanigraph of wind-driven wagon from "The Porcelain Lamp." the teaching of medicine, surgery, dentistry and alHed sciences, as supplemental to actual photographs of anatomical structures and of surgical and dental operations. No matter how clear and sharp and well done a straight picture may be, many aspects can be more clearly and graphically presented in mechanigraph, and usually what is performed on the operating table or in the dentist's chair is far from open, clear and readily understandable. More often than not the actions and parts to be shown are hidden in other parts, impossible to light and concealed with blood. The mechanigraph is able to make them clear, and easily and accurately followed. Fig. 9 — Mechanigraph of Daimer Motorcycle. 6Z
