be seen in the cloud; and I will remember my covenant, which is between me and you, and every living creature of all flesh:  and the waters shall no more become a flood to destroy all flesh.”  It cannot be reasonably supposed, that the rainbow ever appeared before the deluge, nor from our previous remarks, is it at all necessary to suppose it.  Had the patriarchs seen this beautiful phenomenon in an antediluvian world, its recurrence after the deluge could not have been a symbol of security, since, though the spectacle had been already witnessed, the deluge had supervened; but it was a new phenomenon, the consequence of the altered condition of the atmosphere, and was perhaps the result of a super-added law.  The design implies stipulations of a somewhat similar description, and even pagan testimony might be cited as concurring in this view of it.

The Fall of Manna.

This remarkable and providential supply is thus described:  “When the dew that lay was gone up, behold upon the face of the wilderness there lay a small round thing, as small as the hoar-frost, on the ground.”  We are further told, that “when the sun waxed hot it melted;” and when preserved until the following day it became corrupt, and “bred worms.”  To preserve the extra measure which they collected on the sixth day, Moses directed that on that day of the week they were “to bake and seethe” what should be required on the morrow, as on the sabbath none should fall.  It is further added,—­“And the house of Israel called the name thereof manna:  and it was like coriander-seed, white; taste of it was like wafers made with honey.”  Such are the curious and interesting particulars supplied by the Sacred Text.  It is well known that a substance is used in medicine under this name, chiefly obtained from the Calabrias, and is collected from the leaves of the ornus rotundifolia, (fruxinas ornus, of Linnaeus,) and a somewhat similar substance obtains in the onion; but from its purgative qualities, it is sufficiently obvious that the manna of the Scriptures is altogether different.  According to Seetzen, Wortley Montague, Burckhardt, and other travellers, a natural production exudes from the spines of a species of tamarix, in the peninsula of Sinai.  It condenses before sunrise, but dissolves in the sun-beam.  “Its taste,” it is added, “is agreeable, somewhat aromatic, and as sweet as honey.  It may be kept for a year, and is only found after a wet season.”  The Arabs collect it and use it with their bread.  In the vicinity of Mount Sinai, where it is most plentiful, the quantity collected in the most favourable season does not exceed six hundredweight.  The author of the “History of the Jews” has a note to the following effect:
