Others, who carry their researches still deeper, and pretend to have a distinct knowledge of the effect of aliment through all its changes on the human constitution, think, that the amorous disposition, imputed to Neapolitans, is only in part owing to their voluptuous climate, but in a far greater degree to the hot, sulphureous nature of their soil, which those profound naturalists declare communicates its fiery qualities to the juices of vegetables; thence they are conveyed to the animals who feed on them, and particularly to man, whose nourishment consisting both of animal and vegetable food, he must have in his veins a double dose of the stimulating particles in question. No wonder, therefore, say those nice investigators of cause and effect, that the inhabitants of this country are more given to amorous indulgencies, than those who are favoured with a chaster soil and a colder climate. For my own part, I must acknowledge, that I have seen nothing, since I came to Naples, to justify the general imputations above mentioned, or to support this very ingenious theory. On the contrary, there are circumstances from which the opposers of this system draw very different conclusions; for every system of philosophy, like every Minister of Great Britain, has an opposition. The gentlemen in opposition to the voluptuous influence of this climate, and the fiery effects of this soil, undermine the foundation of their antagonists’ theory, by asserting, that, so far from being of a warmer complexion than their neighbours, the Neapolitans are of colder constitutions, or more philosophic in the command of their passions, than any people in Europe. Do not the lower class of men, say they, strip themselves before the houses which front the bay, and bathe in the sea without the smallest ceremony? Are not numbers of those stout, athletic figures, during the heat of the day, seen walking and sporting on the shore perfectly naked; and with no more idea of shame, than Adam felt in his state of innocence; while the ladies from their coaches, and the servant-maids and young girls, who pass along, contemplate this singular spectacle with as little apparent emotion as the ladies in Hyde Park behold a review of the horse-guards? As Sir W—— and L——y H—— are preparing to visit England, and the D—— feels no inclination to remain after they are gone, we intend to return to Rome in a few days. LETTER LXVIII. Rome. We delayed visiting Tivoli, Frescati, and Albano, till our return from Naples.
