The stake entered just in front of the right spermatic cord, passed beneath Poupart's ligament into the cavity of the abdomen, traversed the whole cavity across to the left side; it then entered the thorax by perforating the diaphragm, displaced the heart by pushing it to the right of the sternum, and pierced the left lung.
There is recorded an inexplicable case of menstruation from the region of the sternum, and among the curious anomalies of menstruation must be mentioned that reported by Parvin seen in a woman, who, at the menstrual epoch, suffered hemoptysis and oozing of blood from the lips and tongue.
Bates, 'The Naturalist on the Amazons, 1863, vol. ii. p. 284; Wallace, in 'Proceedings, Zoological Society, 1850, p. 206. The vocal organs of various web-footed and wading birds are extraordinarily complex, and differ to a certain extent in the two sexes. In some cases the trachea is convoluted, like a French horn, and is deeply embedded in the sternum.
Such causes might reduce some of the less observed parts affected by flying, while still leaving the wing of full size for occasional flight, or to suit the requirements of the pigeon-fanciers. A change might thus be commenced like that seen in the rudimentary keel of the sternum in the owl-parrot of New Zealand, which has lost the power of flight although still retaining fairly-developed wings.
In the six largest breeds the shortening of the sternum is nearly twice as great as in the three smaller breeds which remain nearest the rock-pigeon in size. We can hardly suppose that use-inheritance especially affects the eight breeds that have varied most in size. If we exclude these, there is only a total shortening of 7 per cent. to be accounted for.
Both the pericardium and left pleura were distended with fresh blood and large clots. Church reports a case of gunshot wound of the heart in a man of sixty-seven who survived three hours. The postmortem examination showed that the ball had pierced the sternum just above the xiphoid cartilage, and had entered the pericardium to the right and at the lower part.
Under these circumstances how can we be sure of the actual efficacy of use-inheritance? Surely selection is as fully competent to effect slight changes in the direction of use-inheritance as it undoubtedly is to effect great changes in direct opposition to that alleged factor of evolution. The shortening of the sternum in pigeons is attributed to disuse of the flight muscles attached to it.
#Tuberculous disease in the axillary glands# may be a result of extension from those in the neck, from the mamma, ribs, or sternum, or more rarely from the upper extremity. We have seen it from an infected wound of a finger. In some cases no source of infection is discoverable.
In 1869 Simpson measured this band and made the distance on the superior aspect from sternum to sternum 4 1/2 inches, though it is most likely that during the early period of exhibition it was not over 3 inches. The illustration shows very well the position of the joining band.
In superficial bones, such as the sternum, the formation of tuberculous granulation tissue in the deeper layer of the periosteum, and its subsequent caseation and liquefaction, is attended by the insidious development of a doughy swelling, which is not as a rule painful, although tender on pressure.
