since 1870, for all kinds of paints, paper size, wall paper size, 

 pastes and so forth. 



Now let me tell only some uses of "Casein" or u Casein ,, 

 preparation from skim milk. It is used as sizing for straw 

 and felt hats, for the manufacture of paper and glazed paper, 

 tor glazing and finishing leather, for finishing and sizing silk, 

 wool, linen and cotton thread, or piece goods, for the manufac- 

 ture of wall paper, linoleum and various combination goods, 

 and the finishing of the best grades of burlaps. 



"Casein" produces furthermore, cements, putty, mucilage, 

 glues and woodfillers. It is also used in printing ink, for the 

 manufacture of all kinds of dry paints, water and fire-proofing, 

 billiard balls, golf balls, buttons and various fancy articles to 

 replace ivory, are made from "Casein." "Casein" has also been 

 used in the so-called "Lost Arts." We are astonished by the 

 freshness of the Mural paintings and decorations of European 

 churches and palaces, and it is nothing else but "Casein" mixed 

 with colors by the old masters, and is the means of perpetuating* 

 their canvasses and mural paintings. "Casein" either in the 

 form of buttermilk or milk mixed with lime and sand played 

 also an important part as mortar in the erection of monumental 

 buildings thousands of years ago, and it is a well known fact 

 that the mortar became harder with age than the material it- 

 self. 



We have, for instance, in Marienburg, Germany, a monu- 

 mental tower called the "Buttermilk" tower, built by the Ro- 

 mans, and it is a historical fact that this venerable old monu- 

 ment has withstood the onslaught by the ancient and modern 

 war machines to which it was subjected to through the many 

 invasions from the time of the Romans up to the Napoleonic era. 

 I tried myself to dig out a piece of mortar, but the result was a 

 broken knife blade and no souvenir. And I have only mention- 

 ed some of the uses of "Casein." 



The latest utilization of the skim milk was accomplished 

 last year in the manufacture of my own invention, "Dermi for- 

 ma," an article for tanning purposes in all branches of the tan-
