taken in the drying process, owing to the fact that all 

 masses containing much water shrink and easily crack 

 while drying. 



"The adhesive properties of casein have already met with 

 extensive industrial application. Great success has at- 

 tended, for example, the attempts made to render celluloid 

 uninflammable by admixtures of casein; and special men- 

 tion will be made later of the newest celluloid substitute, 

 galalith. This affords an instance of how modern ingenuity 

 has enabled a raw material, hitherto of but slight use 

 technically, to become of great industrial utihty." 



And so we have an imitation ivory and horn, and insu- 

 lating preparation, and antiradiative and anticorrosive 

 substance for covering steam and refrigeration pipes, a 

 covering for floors that resembles Hnoleum, imitation 

 leather, etc.

"At the Hygienic Milk Supply Exhibition which was 

 lately held at Hamburg, the Vereinigten Gummiwaren- 

 Fabriken, of Hamburg and Vienna, exhibited a number of 

 objects which seemingly had nothing to do with the Hy- 

 gienic Milk Supply. There were shown nicely arranged in 

 glass boxes, combs, seemingly made of bone, cigar holders 

 with amber-colored mouthpieces, knives and forks with

 brellas and canes, and bells, rings, chess figures, dominoes, 

 etc., also a small table with an inlaid marble slab, and finally 

 a number of thick slabs and staves of every imaginable 

 variation of marble colors, but of considerably less weight

 stone." 



Manufacture of Galalith. — This peculiar substance 

 known as milk stone is prepared, according to Scherer, by 

 the following method: Casein, prepared by precipitation 

 with rennet instead of an acid, is mixed with 13 times its
