Page 200 - To circulate the blood round the body" or (in more detail) "To convey oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs...
Page 88 - Below the prism is an achromatic eyepiece, having an adjustable slit between the two lenses; the upper lens being furnished with a screw motion to focus the slit. A side slit capable of adjustment admits when required a second beam of light from any object whose spectrum it is desired to compare with that of the object placed on the stage of the microscope. This second beam of light strikes against a very small prism, suitably placed inside the apparatus, and is reflected up through the compound...

Page 271 - The bulb is therefore heated, when the air within expands, and a portion escapes in bubbles through the mercury. On cooling, the pressure of the external atmosphere forces a quantity of mercury through the tube into the bulb. By repeating this operation a few times, the bulb and a portion of the tube are filled with mercury. The whole is then heated till the mercury boils, thus filling the tube, when the funnel is melted off and the tube hermetically sealed by means of a jet of flame urged by a blow-pipe.
Page 90 - Light entering the aperture near E strikes against the right-angled prism which we have mentioned as being placed inside the apparatus, and is reflected up through the slit belonging to the compound prism. If any incandescent object is placed in a suitable position with reference to the aperture, its spectrum will be obtained, and will be seen on looking through it.
Page 90 - Remove a, and open the slit by means of the milled head, not shown in cut, but which is at right angles to d d. When the slit is sufficiently open, the rest of the apparatus acts like an ordinary eyepiece, and any object can be focussed in the usual way. Having focussed the object, replace a, and gradually close the slit till a good spectrum is obtained. The spectrum will be much improved by throwing the object a little out of focus. Every part of the spectrum differs a little from adjacent parts...
Page 266 - The Specific Heat of a body is the ratio of the quantity of heat required to raise that body one degree to the quantity required to raise an equal weight of water one degree.
Page 144 - I inserted into it a brass pipe whose bore was one-sixth of an inch in diameter ; and to that, by means of another brass pipe which was fitly adapted to it, I fixed a glass tube, of nearly the same diameter, which was nine feet in length : then untying the ligature on the artery, the blood rose in the tube eight feet three inches perpendicular above the level of the left ventricle of the heart...
Page 144 - ... inches, and have there for a time the same vibrations up and down at and after each pulse, as it had, when it was at its full height; to which it would rise again, after forty or fifty pulses.
Page 271 - 087 feet Hence the work developed during an entire stroke is "087 xp foot-pounds. Now this is developed by the descent from 0° to — t" of the quantity of heat necessary to melt a cubic foot of ice ; that is, by 4925 thermic units, the unit being the quantity of heat required to raise a pound of water from 0° to 1* centigrade. Next we can obtain another expression for the same quantity of work ; for, by the tables deduced in the preceding...
