Side 221 - Between the brain and the muscles there is a circle of nerves ; one nerve conveys the influence from the brain to the muscle, another gives the sense of the condition of the muscle to the brain...
Side 145 - There is a small aperture at E in the top of the barrel, to allow the air to make its escape, when the piston is raised. This air-pump may be worked in the usual way, or by the method of continued motion. In commencing the exhaustion of the receiver, the piston is supposed to be below the small aperture at C. The piston is then raised, and the air which occupied the barrel is forced out through the aperture at E. The point of one of the fingers is applied to the perforation, in the same manner as...
Side 306 - I have had occasion to dig up a great number of bowlders, of red sandstone, and of the conglomerate kind, in erecting a cotton manufactory; and it was not uncommon to find them worn smooth on the under side, as if done by their having been dragged over rocks and gravelly earth, in one steady position.
Side 459 - that the moon is inhabited by rational creatures, and that its surface is more or less covered with a vegetation not very dissimilar to that of our own earth.
Side 146 - ... forced out through the aperture at e. The point of one of the fingers is applied to the perforation in the same manner as in playing the German flute. The air easily passes by the finger which, when the piston begins to descend, shuts the opening, and completely prevents the entrance of the external air. The piston is again forced down below the opening c, the air in the receiver rushes into the barrel, and is again expelled by the ascending piston. Since the air in the receiver has no valve...
Side 141 - Its composition is as follows : — decrepitated muriate of soda 100 parts; slaked lime 100; sand 140; clippings of glass, of the same quality, from 50 parts to 200. Sulphate of soda likewise offers a great economy in its employment. The results are very satisfactory. The glasses made with this salt were of a very fine quality.
Side 220 - If all that is necessary to the action of a muscle be a nerve to excite contraction, these branches should have been unaccompanied ; but on the contrary I found that before these motor nerves entered the several muscles, they were joined by branches of the nerves which came through the Gasserian ganglion, and which were sensitive nerves. I found the same result on tracing motor nerves into the orbit, and that the sensitive division of the fifth pair of nerves was transmitted to the muscles of the...
Side 175 - Account of the repetition of M. Arago's Experiments on the Magnetism manifested by various substances during Rotation. By C. Babbage, Esq., and Sir John Herschel.— Phil Trans.
Side 460 - The extreme facility with which sounds are heard at a considerable distance, in severely cold weather, has often been a subject of remark ; but a circumstance occurred at Port Bowen, which deserves to be noticed as affording a sort of measure of this facility, or at least conveying to others some definite idea of the fact.
Side 385 - Improvements in the construction of Cars and other Carriages, and the application of a power ; hitherto unused for that purpose to draw the same ; which power is also applicable to the drawing of ships and other Vessels, and for raising weights, and for other...
