four ears to a stalk. Weight of cob, 280 grains ; weight of ker- 

 nels, 2,070 pounds ; number of kernels on an ear, 325 ; yields 

 1,314 grains from 1. This corn yielded 4.75 per cent, of fat at 

 its height, in refined oil, and 4.11 per cent, in sugar and zeine. 

 The cob ash, 1,000 grains yielded in potash, 3.204 ; soda, 0.492 ; 

 phosphate of lime, 1.000 f phosphate of magnesia, 0.260 ; phos- 

 phoric acid (in the alkalies), 0.300 ; silica, 0.800 ; chlorine, 

 0.196; peroxide of iron, 0.360; unburned charcoal, 1.500; 

 carbonic acid and loss, 1.388. The cob yielded a drying yellow 

 fined oil, 0.323 per cent. ; sugar, 0.242 ; dextrine (gum) and 

 some albumen and extractive, 2.557 ; loss, 0.023, or about 

 3.145 per cent, of the whole weight of the cob. 



Analysis of the ash of Burr's improved wrinkled sweet corn. 

 Cob weighed 480 grains, short and thick, and quite large in 

 proportion to the depth of the kernels. Powdered cob, gave 

 dry oil, 0.179 per cent. ; sugar, 0,065 ; brown extractive matter, 

 0.242 ; gum and albuminous matter, 3.257 ; oil, 3.743 per 

 cent, of the whole cob. The ashes gave, potash, 0.2581 ; soda, 

 0.2104; silica (flint), 0.1250; phosphate of lime, 0.0521; 

 phosphate of magnesia, 0.0279 ; oxide of iron, 0.0416 ; phos- 

 phoric acid, 0.0292 ; chlorine, 0.0292 ; carbonic acid and coal, 

 0.0812. Total, 0.8545 grains or per cent, of the whole cob. 



Analysis of lot of Maryland white Southern corn ; cob 

 weighed 290 grains, was short but not large. Potash, 0.4585 ; 

 soda, 0.1211 ; silica, 0.1720 ; phosphate of lime and magnesia, 

 0.0800 ; oxide of iron, 0.0420 ; phosphoric acid, 0.0290 ; chlo- 

 rine, 0.0340; unburned carbon, 0.2242; carbonic acid and 

 loss, 0.5872. Total, 1.7480. 



Analysis of Southern corn, a red variety from Cape May, 

 New Jersey. Cob weighed 560 grains. Potash, 0.450 ; soda, 

 0.220 ; silica, 0.103 ; phosphate of lime and magnesia, 0.054 ; 

 phosphoric acid, 0.091 ; chlorine, 0.011 ; oxide of iron, 0.032 ; 

 unburned carbon and carbonic acid, 0.389. Total, 1.350. 



Analysis of cob of Tuscarora corn, Longmeadow, Connecti- 

 cut River, Massachusetts. Large grained, rich in starch. Cob 

 weighed 630 grains ; potash, 0.6430 ; soda, 0.1970 ; silica, 

 0.0714 ; phosphate of lime, magnesia rnd oxide of iron, 0.0800 ; 

 phosphoric acid, 0.0800 ; chlorine, 0.0630 ; unburned carbon, 

 0.1430 oxide of iron, carbonic acid and loss, 0.6590. Total, 

 1.9364.
