7. Thus, to take merely instance in the three main elements of which we have just determined the names,--flour, oil, and ambrosia;--the differences in the kinds of pleasure which the tongue received from the powderiness of oat-cake, or a well-boiled potato--(in the days when oat-cake and potatoes were!)--from the glossily-softened crispness of a well-made salad, and from the cool and fragrant amber of an apricot, are indeed distinctions between the essential virtues of things which {232} were made to be _tasted_, much more than to be eaten; and in their various methods of ministry to, and temptation of, human appetites, have their part in the history, not of elements merely, but of souls; and of the soul-virtues, which from the beginning of the world have bade the barrel of meal not waste, nor the cruse of oil fail; and have planted, by waters of comfort, the fruits which are for the healing of nations. 8. And, again, therefore, I must repeat, with insistance, the claim I have made for the limitation of language to the use made of it by educated men. The word 'carp' could never have multiplied itself into the absurdities of endo-carps and epi-carps, but in the mouths of men who scarcely ever read it in its original letters, and therefore never recognized it as meaning precisely the same thing as 'fructus,' which word, being a little more familiar with, they would have scarcely abused to the same extent; they would not have called a walnut shell an intra-fruct--or a grape skin an extra-fruct; but again, because, though they are accustomed to the English 'fructify,' 'frugivorous'--and 'usufruct,' they are unaccustomed to the Latin 'fruor,' and unconscious therefore that the derivative 'fructus' must always, in right use, mean an _enjoyed_ thing, they generalize every mature vegetable product under the term; and we find Dr. Gray coolly telling us that there is no fruit so "likely to be mistaken for a seed," as a grain of corn! a grain, whether of corn, or any other {233} grass, being precisely the vegetable structure to which frutescent change is forever forbidden! and to which the word _seed_ is primarily and perfectly applicable!--the thing to be _sown_, not grafted.
