Genesis 6:15

Thou shalt make - the length of the ark - three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits - Allowing the cubit, which is the length from the elbow to the tip of the middle finger, to be eighteen inches, the ark must have been four hundred and fifty feet in length, seventy-five in breadth, and forty-five in height. But that the ancient cubit was more than eighteen inches has been demonstrated by Mr. Greaves, who traveled in Greece, Palestine, and Egypt, in order to be able to ascertain the weights, moneys, and measures of antiquity. He measured the pyramids in Egypt, and comparing the accounts which Herodotus, Strabo, and others, give of their size, he found the length of a cubit to be twenty-one inches and eight hundred and eighty-eight decimal parts out of a thousand, or nearly twenty-two inches. Hence the cube of a cubit is evidently ten thousand four hundred and eighty-six inches. And from this it will appear that the three hundred cubits of the ark's length make five hundred and forty-seven feet; the fifty for its breadth, ninety-one feet two inches; and the thirty for its height, fifty-four feet eight inches. When these dimensions are examined, the ark will be found to be a vessel whose capacity was more than sufficient to contain all persons and animals said to have been in it, with sufficient food for each for more than twelve months. This vessel Dr. Arbuthnot computes to have been eighty-one thousand and sixty-two tons in burden.

As many have supposed the capacity of the ark to have been much too small for the things which were contained in it, it will be necessary to examine this subject thoroughly, that every difficulty may be removed. The things contained in the ark, besides the eight persons of Noah's family, were one pair of all unclean animals, and seven pairs of all clean animals with provisions for all sufficient for twelve months.

At the first view the number of animals may appear so immense that no space but the forest could be thought sufficient to contain them. If, however, we come to a calculation, the number of the different genera or kinds of animals will be found much less than is generally imagined. It is a question whether in this account any but the different genera of animals necessary to be brought into the ark should be included Naturalists have divided the whole system of zoology into Classes and Orders, containing genera and species. There are six classes thus denominated:

1Mammalia;

2Aves;

3Amphibia;

4. Pisces;

5. Insectae;

6. Vermes.

With the three last of these, viz., fishes, insects, and worms, the question can have little to do.

The first Class, Mammalia, or animals with teats, contains seven orders, and only forty-three genera if we except the seventh order, cete, i.e. all the whale kind, which certainly need not come into this account. The different species in this class amount, the cete excluded, to five hundred and forty-three.
