ALBUMINOUS FOOD FOR RUMINANTS. 



Professor F. Stohmann fed three goats alternately, first 

 with hay alone, and then with hay combined with gluten 

 from wheat. The latter substance was in thin, brittle cakes 

 of a yellowish color, and contained 80.6 per cent, of albumi- 

 nous matter. The amount of milk produced was always great- 

 ly increased by the use of the albuminous food, and decreased 

 by its omission ; the exact amount of the increase, however, 

 was not ascertained, an increased secretion not being appre- 

 ciable for about a week. It was observed that' the effect of 

 the gluten was not immediately shown. 28(7, v.,i!/y, 1872,

CHINESE WHITE CABBAGE. 



According to the Food Journal, the great national vegeta- 

 ble of the Chinese is the white cabbage of Shatung, which is 

 grown all over the northern part of the empire, and which is 

 eaten raw as a salad, said to be equal to the best lettuce, or 

 boiled, in which condition the flavor reminds one of the .finest 

 asparagus. It is both hardy and prolific, surviving the severe 

 winters of the North. Specimens are occasionally met with 

 weighing as much as twenty pounds. 22 A, May 4, 1 872, 430. 



APPARATUS TO PREVENT MILDEW IN GRAIN. 



The Scientific Review contains a description with figures of 

 an apparatus invented by Mr. Joannides, for the preservation 

 of corn, grain, and seed from mildew, heating, etc. This con- 

 sists of a perpendicular cylinder of metal, wood, or other suit- 

 able material, with about eight horizontal cylinders or pipes, 

 connected with and branching from it, the entire apparatus 

 being perforated with small holes for the circulation of the 

 air, but not large enough to allow the grain to pass through. 

 A series of small tubes is placed inside the larger one for the 

 return of the confined air, and for keeping up a circulation. 

 The apparatus thus formed is placed in a ship, granary,, etc. ; 

 the perpendicular cylinder projecting above into the open 

 air having attached to it a funnel-mouthed ventilator, which 

 can be so arranged as to turn toward the current of the air 

 or from it. When arranged like the ventilating hood of a 

 chimney, the current of air will be upward and outward;
