80 Next in importance to its use as a “sizing agent” comes its use as a cold glue. Excellent glues are made merely by stirring up casein with distilled water and a little sodium bicarbonate, sometimes with the addition of shellac. I n the woodworking trade casein glues threaten to displace ordinary gelatin glues because casein glues can be applied cold (so t h a t all the trouble of melting the glue is avoided), can be made waterproof, and b y their use certain delicate effects are attainable in veneering work which are impossible with gelatin glue, since the latter must be applied hot and is not waterproof. Several American firms are now producing these glues in large quantities. When treated with certain chemicals, casein is converted into cxtremely tough, hard substances like bone or ivory, which can be kneaded and moulded when hot and when cold can be polished and worked. The best known of these products is galalith, which is made by treating casein with formaldehyde.

I t forms a tough, white product, which can be colored or marbled when hot by stirring in dyes, soot, etc. It is now used for making piano keys, backs of brushes, imitation ivory articles, and especially as a n insulating medium for electrical fittings. Casein is used as a total or partial substitute for celluloid, but has the disadvantage that it cannot be produced in very thin, transparent sheets. Similar substances are produced by adding to a caustic soda solution of casein various chemicals such as sulfur, water glass, lime, sand, zinc and lead hydroxides, wood meal, cork dust, and so on. Such compositions arc used for producing mouldings for picture frames, friezes, fancy articles, and toys. Casein is also used as a constituent of shoe polishes, etc., and a n important and growing trade is the consumption of casein in foods, such as brain and nerve foods (“Visem,” “Sanatogen,” and “Plasmon”).

William Willard Daniells, emeritus professor o f chemistry a t the University o f Wisconsin, died a t the home o f his s o n , Dr. Ralph P. Daniells, a t Toledo, Ohio, on October Izth, at the age of j z years. He graduated from Michigan Agricultural College in 1864, and then spent about two years in study with \tTolcott Gibbs a t the Lawrence Scientific School o f Harvard University. Dr. Daniells came to the University o f \Visconsin in 1868 as professor of agriculture. The following year analytical chemistry was also included in his department. In 1875 his chair \vas changed t o chemistry and agriculture, and in 1880 he was elected professor of chemistry, the chair of chemistry having been established a t that titnc. Dr. Daniells served n l ~ t only as a teacher o f chemistry, but also as a tncmber c ~ fthc State Hoard of Health, as State Analyst, as chemist tu thc Statc Geological and Natural History Survey, and in other advisory capacities. For several decades hc was onc of the very few reliable chemists of the middle west to whom the public could turn for expert services, and so his influence extended far beyond the university campus. But while this scientific work together with the founding and upbuilding of a strong department of chemistry a t thc university stand to his credit, it is for his qualities as a man that Dr. Daniells will especially be remembered. He \vas an exceptionally strong, pure, lovable Christian character, Ivho always stood for things that ought to be, and who exerted a quiet yet none the less potent influence for good upon his pupils, his colleagues, and all others with whom he came in contact. As a member of the American Chemical Society he always showed a live interest in fostering the work of the Society, and was instrumental in establishing the Wisconsin Section of the Society.

THE PRESENT STATUS O F THE WINDOW GLASS INDUSTRY The total number of hand-operating window glass plants in the United States is 46, but many of these may not be operated throughout the entire year. On October I j , 1912,about 500 hand-operated pots were put into operation, and on November I, 1912,the number was increased to approximately 989.’ This statement refers to factories located in Ohio, Indiana, Pennsylvania and West Virginia; in other sections of the country a possible total of 300 pots can operate if fuel and men are obtainable. The following is a list of the hand-operating plants:
