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.

TROUBLES WITH THE MAGIC LANTERN lCn. I FIG. 24. CARBONS IN BAD POSITION; THE UPPER CARBON CUTTING OFF THE LIGHT FROM THE UPPER PART OF THE CONDENSER, AND HENCE CASTING A SHADOW ON THE LOWER PART OF THE SCREEN. A Carbons at an inclination of about 25 degrees, with the upper or positive carbon too far forward. B Carbons at right angles, with the upper carbon too far forward. S Screen image of the condenser face. As the upper carbon is in the way, the upper part of the condenser is partly in shadow, and hence the screen image will be shaded on its lower part due to the inverting action of the objective. FIG. 25. CARBONS IN BAD RELATIVE POSITION, THE LOWER OR NEGATIVE CARBON EXTENDING UP IN FRONT OF THE POSITIVE CARBON. A Carbons at right angles, with the lower carbon too high. B Both carbons vertical, but the lower or negative one standing in front of the upper one. .V Screen image of the condenser face. As the condenser is not well lighted on its lower part due to the shading action by the lower carbon, the screen image will be shaded correspondingly on its tipper part due to the inverting action of the objective.
