From this table I extract the following:—
| Starch, gum, &c. | Gluten, albumen, &c. | |||
| Wheat flour. | 55 | lbs. | 10 to 15 | lbs. |
| Oats | 65 | " | 18 | lbs. |
| Indian corn | 70 | " | 12 | " |
| Beans | 40 | " | 28 | " |
| Peas | 50 | " | 24 | " |
| Potatoes | 12 | " | 2⅓ | " |
The Professor remarks that the proportion of oil is, in 100 lbs. of
| Wheat flour | 2 to 4 |
| Oats | 5 to 8 |
| Indian corn | 5 to 9 |
| Beans and peas | 2½ to 3 |
| Potatoes | 0¼ |
Maize is one of those plants in which potash preponderates, for analysis of its ashes gives the following proportions:—
| Salts of potash and soda | 71.00 |
| Salts of lime and magnesia | 6.50 |
| Silica | 18.00 |
| Loss | 4.50 |
| 100. |
Dr. Salisbury has also furnished the proximate analysis of five varieties of ripe maize or Indian corn:—
| One hundred grains of each. | Proportions. | |
| Water. | Dry. | |
| Golden Sioux corn, a bright, yellow, twelve-rowed variety, frequently having fourteen rows | 15.02 | 84.98 |
| Large eight-rowed yellow corn | 14.00 | 86.00 |
| Small eight-rowed ditto | 14.03 | 85.97 |
| White flint corn | 14.00 | 86.00 |
| Ohio Dent corn, one of the largest varieties of maize | 14.50 | 85.50 |

Large quantities of starch are now made from this grain in Ohio; an establishment near Columbus consume 20,000 bushels of corn annually for this purpose. The offal of the grain is given to hogs, 500 to 600 head being annually fattened therewith. The quality of the starch is said to be superior to that of wheat, and commands a higher price in New York.
