We have attempted to find the origin of this opinion in regard to fish but without success. In fact it has not the support of popular notoriety which arises insensibly from daily observation. Thus Benoislon has proved directly by statistical facts that fecundity is not greater among the inhabitants of maritime coasts than among those who live in other places. (_Bulletin de Férussac_, Jan., 1827.) Villermé has noticed that in Greenland and among the Esquimaux, who live principally on fish, on sea-calves, that is, aliments, containing these oily parts, which are regarded as so prolific, women have rarely more than two or three children during their life. Besides if fish has the property ascribed to it, why is it that during Lent, that period of the year when this form of food is most used, the procreative power should be most inactive; a fact which is proved from documents collected in almost every country by the laborious investigations of Villermé. (_Annales d’hygiene publ._, Jan. 1831.) Hence it is extremely improbable that fish possesses this property, which it is important to establish in order not to discard from the regimen of youth, an article of diet which being both nutritious and slightly stimulating, is well adapted to prevent genital excitement or to subdue it. Many other articles of food beside fish have been regarded as aphrodisiac. Many insect eating reptiles, a bird called torcol and numerous insects of which it is useless to speak. Eggs have also been regarded as having the same property, and also truffles, mushrooms, artichokes, celery, cocoa and all its preparations, onions and condiments as ginger, pepper, and vanilla, and finally certain fruits as strawberries, apricots, peaches, pineapples, &c. Among the articles which we have named there are certainly some which being heating and exciting, may cause desire although containing nothing more specific than a great many substances which are esteemed as antiaphrodisiac, because being cooling and soothing they may produce the opposite effect. Among these latter, we find milk, which, according to Ste. Marie, generally contributes less to form the semen than most other articles of food. Among these also we may mention fresh vegetables and particularly the sorrel, purslain, lettuce, endive, cucumber, mushroom, melons, &c. To these may be added the flesh of young animals, chicken, lamb, veal, &c., and also cooling drinks, as orgeat, lemonade, &c. The regimen best adapted for appeasing all carnal desires consists as we have seen in an antiphlogistic diet which is composed of those fluids or solids which when introduced into the stomach are digested and assimilated with the slightest possible degree of excitement and heat. This regimen is that which should be prescribed to those patients who possess a certain degree of vigor and wish to protect themselves against urgent and dangerous desires.
