On sterility in the male and female, its causes and treatment. principally on the analogy of structure of this organin the females of oviparous and viviparous animals. • Tinchant, Doct. novo sur la product de Ihomme. 40 STERILITY—CAUSES—TREATMENT— Steno (Diss, piscium)^ Malpighi (de Gener. pull, inovo.)f Harvey {de Genet, ovi.), Vallisniery {de ), Haller {Physiology), and Bonnet {Sepul-chret. anet.), who have adopted it, regard the vesiclesin the ovaries as so many ova, which contain all thelineaments of the new being, and which require onlythe contact of the semen to receive life. Bonnetthinks that these germes pre-existed in the ovaries sincethe commencement of the world, boxed in one withinanother, and developing themselves successively bythe effect of generation ; but this opinion which findsbut few partisans except in the Italian schools, is nownearly abandoned. Some naturalists have also thought they found inthe male semen animalcules, such as are seen in thecut (fig. 13), which by their development might be- [Fig. 13.]. 1. Animalcules of a man, taken from the vas deferens immediateljafter death. 2. Seminal granules. 3. A bundle of animalctiles as group-ed together in the testicle. 4. Seminal globule. 5. Same surrounded bya cyst or bag. IN THE MALE AND FEMALE. 41 come beings similar to those producing them. Leu-vvenhoeck {Afiat. epistoL varice.), Boerrhaave (Physi-ology), Geoffroy (Monstrosities), Lieutaud ( Traitedanat.), &c., who have advanced this idea, think thatthe vesicles of the ovaries are only the envelope orthe nest of the ovum, which must receive that of theanimalcules victorious in the strife established betweenthem at the moment of the reproductive act. But thisopinion, which is as improbable as that of the boxingup, has but few partisans. Throwing aside these last two hypotheses, it is cer-tain that the system of the ovarists combines in its favorthe most votes and the greatest probabilities. It ismore in accordance with th
