 with water — produce about the same effect on the degree > 

 of shrinkage. 



" In the average small store refrigerator, the loss will 

 approximate the limit set by law in a space of ten days 

 when the prints are piled loosely on shelves."

 of many other states, and reads as follows : " The maxi- 

 mum variation allowed on a pound print to be three- 

 eighths of an ounce on an individual print, provided that 

 the average error of twelve prints, taken at random, shall

 on the market. He placed the printer on sale about 1892. 

 It molded a single print at one time, and was operated by 

 a lever. Later several block printers, as seen in Fig. 50,
