In confirmation of this, we may, with great propriety, adduce the testimony of Dr. Wallis on the loss of nerve-power, and the process through which the result is produced, who observes, that "the phenomena which are exhibited when the deleterious air has been drawn into the lungs are these: the great gastro-pulmonary nerve is either wholly or partially paralyzed, the consequences are the cessation of all its functions either wholly or partially. This great nerve is a nerve of function, and performs the functions of digestion and respiration, and influences all secretions." Hence it appears the nervous power generally, as before observed, is very early and essentially impaired, and to such an extent that there can be no rational hope of relief, unless some remedial agent can be found that will exercise such a controlling influence and power, as shall be adequate to restore the tone of the nervous system. Hence, we are forced to the conclusion that the prominent, leading, and most urgent symptoms requiring special attention, are "the Algide" or loss of temperature, the loss of nerve-power in the ganglionic and pneumogastric nerves and their branches, the altered or disorganized condition of the blood, the impaired or obstructed circulation, and the early and direct tendency to congestion. These are the prominent and essential features to be observed in the treatment. They are too intimate, dependent and inseparable, to warrant any attempt to mark the precise order of their development. They are the essential phenomena, proceeding equally and directly together from the primary cause and disease action, and strictly constitute the complex character of the cholera, and exhibit its main, distinguishing features, which must necessarily govern and dictate the maxims of rational practice in the treatment of this disease. The object, then, of first importance is to restore the lost temperature, the caloric already eliminated, and prevent its further depression; to restore, at the same time, the lost nerve-power to the nerves again; to arrest the process of disorganization of the blood, and equalize the circulation; to relieve and suspend the congestion; and then, according to all the experiments which have been made, the consequent and dependent phenomena of the cramps and the vomiting and the purging will disappear.
