Page 902 - ... already frequently referred. "Next I tried the medulla oblongata ; the effects of the stimulation of this organ were much the same as those produced by irritating the cord. " I then tried the corpora quadrigemina and the mesocephale. Having passed fine bradawls into the cranium, in such a direction as I had previously satisfied myself would lead to this organ, I subjected it to the influence of the machine ; general convulsions were produced, of a character essentially different from those which...
Page 882 - An' getting fou and unco happy, We think na on the lang Scots miles, The mosses, waters, slaps, and styles, That lie between us and our hame, Whare sits our sulky, sullen dame, Gathering her brows like gathering storm, Nursing her wrath to keep it warm. This truth fand honest Tam o...
Page 427 - But if the current is run only transversely, across a nerve or muscle, it has only a little and uncertain effect. These views we conceive to be fundamental. Nevertheless, the large practical experience and learning of Dr. Duchenne, of Paris, lead him, it appears, to the following somewhat different conclusions, which are condensed, but not altogether indorsed, by the author : — 1. "In man, whatever may be the direction of the currents, or the degree of vitality of the nerves they traverse, the...
Page 31 - C is nothing more than the result of a particular modification in the state of bodies. This modification probably depends on the mutual action exercised on each other by the ponderable particles of matter, and the subtle fluid that surrounds them on every side...
Page 1063 - The battery is a compound one of Smee's, and consists of six pairs of plates of zinc and platinized silver, contained in six cells, which are set in action by one fluid, viz., dilute sulphuric acid. The battery may of course vary according to the choice and taste of the operator, but it is desirable to render it as elegant and as simple in
Page 902 - The experiments weie performed on rabbits. I took the spinal cord first ; here we had the well-known tetanic effects to which I have already frequently referred. Next I tried the medulla oblongata : the effects of the stimulation of this organ were much the same as those produced by irritating the cord. I then tried the corpora quadrigemina and the mesocephale. Having passed fine brad-awls into the cranium in such a direction as I had previously satisfied myself would lead to this organ, I subjected...
Page 281 - ... functions of the body are performed. The oxygen contained in the red blood burns up the organic molecules with which it is in contact, and produces heat, without which life is impossible. Under the influence of electricity is effected, during digestion, the selection of the nutritive molecules and their assimilation. The same action takes place in respiration and in all the other functions. These facts perfectly agree with the electric phenomena of combustion. The carbon takes the negative electricity...
Page 385 - As a means of diagnosis between actual paralysis of sensation and mere subjective anaesthesia, in which the tactile powers are unaltered. 3. As a means of determining the progress of a given case of paralysis for better or for worse.
Page 281 - Scoutetten has reported to the Academy of Sciences at Paris an account of some experiments made upon horses which were previously made insensible to pain. He found that the electric positive sign, indicating the direction of the current, was constantly from the red, or arterial, to the black, or venous, blood. He concludes his memoir by saying that since it is demonstrated that the red blood and the black blood, in their contact through the walls of the vessels, which act as true porous vases, give...
Page 920 - If it is intense, we administer the larger quantity ; if very moderate, the lesser will answer. Under the combined action of the mercurial and quinine, free evacuation of the bowels will usually occur, but rarely excessive. Three or four hours are now suffered to elapse, during which the topical bleeding is repeated, if the local symptoms do not yield. The condition of the patient will now be found generally much improved. The cerebro-spinal pain is either removed or mitigated, the pulse less frequent,...
