While the danger of glass wind-shields and windows in automobiles in case of accident has always been realized, the use of ordinary celluloid as a substitute has been materially lessened by reason of its well-known inflammability. One window might easily be caused to explode from contact with a lighted cigar, and this might be sufficient to ignite all the others and surround the car with flame. But now the Germans have invented a method of fire-proofing this material, and the process has not only made it safe, but tougher as well. Sheets as large as 100 square feet have been made and from six to eight-hundredths of an inch in thickness. It is softer and more like leather in texture than the ordinary celluloid, and is capable of being bent, rolled or sewed into the material of an automobile top without injury. Another particularly advantageous feature is that sunlight does not turn it ye_____low as it does the old-style celluloid.
