Liniment. Sap. Comp.℥i
Tinct. Iodinæ,℥i m.

Some patients can bear this quantity rubbed into the tumour once, and sometimes twice a day; though in some, the skin is so tender, that the liniment cannot be so frequently used. Dr. M. prefers this liniment to the common iodine ointment, as less liable to evaporation. In France, we believe Dr. Richond prefers rubbing in the tincture itself. The following remarks are useful:

"In some individuals, after the preparations of iodine have been given internally for some time, they are apt to occasion headach, giddiness, sickness of stomach, with some degree of nausea, langour, and inaptitude for exertion; when these unpleasant sensations and effects occur, the best plan to remove or obviate them is to suspend, for a time, the use of the medicine, or to reduce the dose, as may seem most expedient." A reduction of dose, from fifteen to twelve drops, was the plan adopted by our author on this occasion.

2d. Paralysis.—Want of success with the ordinary modes of treating this disease, induced Dr. Manson to try the effects of iodine.

"The wonderful powers of iodine, which I had recently witnessed; and a long previous acquaintance with the same remedy as it exists in burnt sponge, in reducing morbid enlargements of the thyroid gland, led me from analogy, to think, that in cases of palsy, from tumours or fluids pressing on the brain or spinal cord, or from morbid thickening of the investing membrane of the cord itself, iodine might prove a useful remedy not only by stimulating the nervous system, and removing morbid tumefaction and effusion, but also by correcting the strumous state of the constitution that often gives rise to the disease."

The following interesting case as abridged in the Medico-Chirurgical Review, for January 1826, we take the liberty to transcribe.

"J. Watterton, aged 19, was admitted into the General Hospital of Nottingham, on the 27th of March, 1821, having been ailing since October, 1819. Stated that he had at first been attacked with pain in the bowels, which having ceased, the lower extremities became swelled and painful.

"After this, his neck became stiff and painful, with shooting pains from the neck into the left side of the head. These also disappeared, and did not afterwards return. This was about nine months ago, and, at that time, he suddenly lost the power of the left arm, and in a short time afterwards, that of the left lower extremity. Some time after this, he recovered, partially, the use of the left arm; the leg remaining paralytic. About this time, the right half of the body was instantaneously and completely palsied. He has continued ever since in this wretched state, getting worse rather than better, passing his stools and urine, involuntarily. He lies on his back, and, with the exception of the left arm, he is completely paralytic on both sides, from the neck downwards. The sense of feeling is very much impaired—there is no distortion of the face, nor impediment of speech. Is troubled with twitchings in the lower extremities. Purgatives—blisters to the nape of the neck, and to be kept open.

"It appears that, about two years ago, he had a bloody purulent discharge from both ears. The left still continues to discharge a purulent looking matter. Purgatives were continued till the 6th of April, when the tincture of iodine, in doses of 15 drops, was given thrice a day. April 9, can raise the right arm nearly to the head; but the power of the lower limbs has not improved. The twitchings have decreased. Purgatives—the tincture of iodine to be increased to 20 drops ter in die. 10th. Evinces some muscular power in the lower extremities to day—feels stronger—can retain his urine for some time. 14th. Continues to improve. The left foot is become exquisitely sensible, and that extremity is often drawn up spasmodically towards the body. The iodine to be increased to 25 drops. 16th. The paralytic symptoms continue to yield to the powerful influence of the iodine. When his meat is cut, he can now feed himself with the left hand;—can raise the right hand to the chin, and draw the right upper extremity up towards the body. He continues to hold his water. The iodine is increased to 30 drops, thrice a day—from this date to the 7th of May, the medicine was occasionally obliged to be intermitted and again commenced in smaller doses. At this period, however, the patient could walk from his bed room to the day ward with very little assistance. 19th. He can walk without any assistance, except that of a stick to steady him. June 9th, can walk without a stick. He is gradually recovering the power of motion and sense of feeling. Drops agree. Appetite good, and is allowed full diet. July 3d, the patient was discharged cured."

Besides this highly interesting case, 24 more of paraplegia, hemiplegia, and partial paralysis, are given in detail, in which the iodine was exhibited with various success. In his prefatory remarks to this chapter, Dr. Manson observes, that although he has been able to cure only a proportion of the cases of palsy that have come under his care since April 1821, yet he has been much more successful in his practice since that time, than he was previously with the use of all the ordinary means.
