Lane reports a supernumerary testis found in the right half of the scrotum of a boy of fifteen. In a necropsy held on a man killed in battle, Hohlberg discovered three fully developed testicles, two on the right side placed one above the other. The London Medical Record of 1884 quotes Jdanoff of St.
The lilt of his lines is capable of ringing, and does so again and again, into something very like the thrill and resonance of the Grand Manner. Listen for it especially in the third and fourth lines of this: Quid debeas, o Roma, Neronibus Testis Metaurum flumen et Hasdrubal Devictus, et pulcher fugatis Ille dies Latio tenebris.
In this case the influence of a parasite predominantly female would seem to be the real cause of the development of eggs in the testis of the host.
There is complete disagreement between the results of Ancel and Bouin on the one hand, and those of Shattock and Seligmann on the other, with regard to the effects of ligature of the vasa deferentia. The latter authors, as mentioned above, found that after ligature not only the somatic characters but the testis itself developed normally.
The two most primary sexual organs are the testis and the ovary; it is the object of conjugation to bring into contact the sperm from the testis with the germ from the ovary. There is no reason to suppose that the germ-cell and the sperm-cell are essentially different from each other.
Many investigators have found that the Roentgen rays destroy the spermatic cells of the testis in Mammals, leaving the cells of Sertoli, the interstitial tissue, nerves, and vessels uninjured. G. d. Roy. It seems possible, although no such suggestion has been made, that the interstitial cells might either normally or exceptionally give rise to ova and spermatocytes.
Denique linguarum cognitione praeditus, ne tot ac tantarum rerum varietates, et miracula quae oculatus testis viderat, memoriaeque mandauerat, obliuione premerentur, in tribus linguis, Anglica, Gallica, et Latina, graphice scripsit Itinerarium 33. annorum.
In the F1, when the horned character in the female is only inherited from one side, the hereditary tendency is not enough to overcome the influence of the absence of the testis hormone and presence of the ovarian hormone, and so the horns do not develop.
Another drake was castrated on August 8, 1909: only the left testis was removed, the other being ligatured. At this time the bird would be in eclipse plumage. It appears from the description that it assumed the nuptial plumage in the winter of 1909, and did not pass into eclipse again in the summer of 1910.
For, when questions belonging to the most sacred hereditary beliefs of Christendom were supposed to be affected by the verification of a fossil shell, or the proving that the Maestricht "homo diluvii testis" was, after all, a monstrous eft, it became necessary to work upon Conchology, Botany, and Comparative Anatomy, with a care and a reverence, a caution and a severe induction, which had been never before applied to them; and thus gradually, in the last half-century, the whole choir of cosmical sciences have acquired a soundness, severity, and fulness, which render them, as mere intellectual exercises, as valuable to a manly mind as Mathematics and Metaphysics.
