Mercury, given until it produce salivation has frequently cured Phthisis Pulmonalis. It is used with greatest advantage in its first stage, but after the inflammatory action has been in some measure reduced, by means of blood-letting, and the other remedies proposed. Before these evacuations have been premised, it would tend rather to increase the inflammation; while in the advanced stage it would add too much to the debility of the patient. It generally succeeds only when it affects the mouth, and therefore to secure this effect and prevent its running off by the bowels, it should be combined with opium. But the best form of exhibiting mercury, is one much in use with my worthy friend and preceptor, Dr. Borrowe. Calomel, combined with small doses of antimonial powder, given morning and evening, until it affect the mouth, is the form proposed. In this way it may be given at an earlier period of the disease, than would otherwise be proper, by the constant determination to the skin kept up by the antimonial powder, obviating the tendency which mercury has to increase inflammatory action. At the same time it serves to keep the bowels open, and makes almost every other medicine unnecessary. On the other hand, if it acts too much on the bowels, it may be usefully combined with opium, which adds to its diaphoretic effect. The good effects of this mode of exhibiting mercury, is strikingly illustrated by the result of the following case, which occurred in the practice of Dr. Borrowe within a few months past. “Miss ------, aged about 14 years, had been for six months past, afflicted with some cough, pain in the chest and difficulty of breathing. She was affected with loss of appetite, emaciation and profuse sweats at night. Her pulses were frequent; she had the peculiar pearl-like appearance of the adnata; frequent attacks of diarrhœa, and an expectoration much resembling pus. She was attacked with chills about the middle of the day, followed by considerable excitement, aversion to motion and drowsiness; succeeded by great prostration of strength; palpitation and hurried breathing on ascending a height or engaging in any considerable bodily exertion; attended with a livid appearance of the lips, evidencing a difficulty in the passage of blood through the lungs. It was determined to put her upon the use of Calomel and Pulv: Jacob: which were given in small doses every night and morning; a blistering plaister was also applied to the chest, and kept in an irritable state for a considerable length of time. The diet was ordered to be soft, mild and nutritious. The mercury and antimonial medicine were occasionally omitted when they acted more on the bowels than the skin, or occasional anodynes were administered to restrain their action on the alimentary canal.
