It appears that the disease in its ancient form is still prevalent in certain parts of the world; as, for example, in the Sardinian States, where it is still looked upon as being both contagious and hereditary. It is also endemic in Norway: nay, it is reported to have broken forth with all its ancient character in the province of New Brunswick. In the East, elephantiasis and leontiasis are still considered as aggravated forms of leprosy. (See Heber’s Travels, ii, 50; and Niebuhr’s Travels, xxvii, 11.) We may be allowed to add, in conclusion, that a great mass of misapprehension has prevailed in modern times regarding the elephantiasis of the Greeks and Arabians. We trust the above sketch will remove the difficulties which formerly beset this subject.
SECT. II.—ON LEPROSY AND PSORA.
Both these affections consist of an asperity of the skin, with pruritus or wasting of the body, having their origin from a melancholic humour. But leprosy spreads over the skin more deeply in a circular form, throwing out scales which resemble those of fishes. But psora is more superficial and variously figured, and throws out furfuraceous bodies. In these cases we must premise venesection when the body appears more than usually plethoric; but, if not, we must by all means purge with those things which evacuate black bile. Externally we may use in common either of the hellebores; and have washed lime dried, and, when going to use it, we may dilute it in water until it attain the thickness of the wrestler’s sordes, and anoint.—Another: Of sage, of the tears of Æthiopian olive, of each, dr. viij; of the bark of capper’s root, of gum, of each, dr. xiij; anoint with vinegar, in the sun. Anemone, when applied, and the root of the white vine particularly, remove psora. But the following are compound remedies: Of the flour of darnel, one chœnix; of the white cardamom, dr. iv; of the scum of natron, dr. j; of copperas, dr. viij; of the middle roots of asphodel, dr. iv; having triturated them in vinegar, and made of the thickness of a cerate, anoint, having first applied nitre to the part; and having removed it, (which do about the third day,) and washed with cold water, again anoint.—Another: Of the juice of kings’ spears’ roots, oz. vj; of sulphur vivum, of manna, of each, dr. x; of natron, dr. viij; anoint, mixing with vinegar. The following simple remedies are particularly applicable for psora: Stavesacre, bitter lupins, cardamom with vinegar, the root of lily with honey, turpentine rosin, sulphur, chick peas, goat’s dung; and these compound ones—mix equal parts of chalcitis and misy with wine, and anoint the more humid kinds of psora.—Another: Boil the tender leaves of rose-bay in a sextarius of oil until they are dried, and, throwing away the leaves, add to the oil oz. iij of white wax, and, after it is dissolved, cool and sprinkle upon it oz. j of sulphur vivum, and anoint in the sun or in the bath. Some boil also squills with the rose-bay.—Another: Of diachylon, oz. ij; of wax, oz. ij; of oil of roses, oz. j; of litharge, oz. iij; of ceruse, oz. iij; of liquid pitch, oz. vj; of the dross of silver, oz. ij; of siricum, oz. ij; of vinegar, what will be sufficient for the trituration of the dry things.—Another: Of ceruse, oz. ss; of starch, oz. ss; of lead, oz. j; of red lotuses, or of alkanet, oz. ij; of wax, oz. vj; of oil of roses, oz. ix; boil the alkanet properly with the oil of roses, and then add the other things.—Another: Take ten eggs, or as many as are required, and having macerated in the most acrid vinegar until their shell become tender; boil in the vinegar the yelks of them; having triturated with rose-oil and what remains of the vinegar a moderate quantity of litharge, anoint, when of the consistence of the sordes of oil in baths.—Another: Three yelks of eggs out of vinegar; of rose-oil, oz. vj; of sulphur vivum, oz. iij; having triturated the yelks of the eggs and the sulphur with the vinegar, add the cerate. And litharge triturated with vinegar and rose oil, until it be of the consistence of a plaster, cleanses the most acrid kinds of psora; and the detergent ointments from dock, and the most of those for elephantiasis, answer well in general with leprosy and psora.

As in the preceding chapter, we shall here give a separate account of the views of the Greeks, Latins, and Arabians, beginning, in this instance, with the Greeks.
Hippocrates makes only casual mention of these diseases, and has nowhere marked their distinguishing characters. In one place he calls leprosy a blemish rather than a disease; and in another he remarks that some varieties of it itch before rain. He speaks of vinegar, and of lime and water as remedies for it. It is proper to apprize the reader that the two works quoted above from the Hippocratic Collection are, most probably, not genuine.
Galen also is very deficient on the subject of lepra, having nowhere given a complete description of it, although he notices it incidentally in many parts of his works. In one place he calls elephas, leuce, and alphos cognate affections. Alphos, he says, is much more superficial than leuce. In another, he attributes these complaints to the melancholic humour which becomes fixed in the skin. In the ‘Isagogue,’ which, however, seems not to be a genuine work of his, it is said that lepra is an affection of the skin, which becomes whiter and rougher than natural, the roughness resembling that from prominent psydracia. Psora is said to partake more of the nature of ulceration. Both are represented as arising from a saltish phlegm, and as being cured by phlegmagogues, and ointments rubbed into the skin. It is also stated that leuce is distinguished from lepra by there being no roughness of the skin in the former disease. In another place he mentions psora as a disease most inveterate to cure. (Facult. Natur. i, 13.)
Oribasius thus distinguishes leuce, alphos, melas, lepra, and psora from one another. Leuce is occasioned by a pituitous and viscid blood, which, in process of time, renders the colour white. Alphos arises in like manner, but the superficial skin only is affected, and not the whole flesh. When a pituitous humour is the cause of the complaint, it puts on the appearance of alphos, and when the melancholic, of melas. Lepra affects mostly the deep-seated parts, and psora the superficial. For all these complaints he recommends a mixture of lime and water and some other such things.
In the ‘Euporista,’ generally ascribed to Dioscorides, there is given a long list of medicinal articles for lepra, such as the flour of darnel with sulphur, hellebore with vinegar, verdigris, cantharides, &c.
