Page 273 - The instances of greatest variation in the quantity of blood contained, at different times, in the same organs, are found in certain structures which, under ordinary circumstances, are soft and flaccid, but, at certain times, receive an unusually large quantity of blood, become distended and swollen by it, and pass into the state which has been termed erection. Such structures are the corpora cavernosa and corpus spongiosum of the penis in the male, and the clitoris in the female: and, to a less...
Page 472 - They are soluble in water, are not coagulated by heat, and are not precipitated by nitric acid, copper sulphate, ammonium sulphate, and a number of other precipitants of proteids. They are precipitated but not coagulated by alcohol. They are also precipitated by tannin, picric acid, potassio-mercuric iodide, phospho-molybdic acid, and phospho-tungstic acid.

Page 699 - ... cavities is denser than that around it, and forms the osseous labyrinth; the membrane within the cavities forms the membranous labyrinth. The membranous labyrinth contains a fluid called endolymph ; while outside it, between it and the osseous labyrinth, is a fluid called perilymph.
Page 393 - Corpuscles, which are, for the most part, coloured, and it is to their presence in the fluid that the red colour of the blood is due. Even when examined in very thin layers blood is opaque, on account of the different refractive powers possessed by its two constituents, viz., the plasma and the corpuscles. On treatment with chloroform and other reagents, however, it becomes transparent, and assumes a lake colour, in consequence of the colouring matter of the corpuscles having been discharged into...
Page 232 - Cardiograph (fig. 166) consists of a cup-shaped metal box over the open front of which is stretched an elastic India-rubber membrane, upon which is fixed a small knob of hard wood or ivory. This knob, however, may be attached, as in the figure, to the side of the box by means of a spring, and may be made to act upon a metal disc attached to the elastic membrane.

Page 341 - When by the efforts of the expiratory muscles, the chest has been squeezed to less than its average diameter, it again, on relaxation of the muscles, returns to the normal dimensions by virtue of its elasticity. The construction of the chest-walls, therefore, admirably adapts them for recoiling against and resisting as .well undue contraction as undue dilatation. In the natural condition of the parts, the lungs can never contract to the utmost, but are always more or less
