It is unnecessary to adduce the opinions of modern authors in support of the occasional hereditary transmission of leprosy, as all observers who have described the disease from their own observations, and that in the most different and distant parts of the world, seem uniformly agreed upon this point. Dr. Heineken, in his account of the inmates of the leper hospital at Funchal, Madeira, in 1825,[280] states that in three of the cases no hereditary taint was known; the aunt of a fourth (p. 21) was a lazar; the uncle and two brothers of a fifth (p. 18) laboured under the same disease; the mother, brother, and son of a sixth (p. 19), were lepers, and all of them affected before himself; and in a seventh case (a female aged 35) her father, mother, three sisters, and two brothers, had already all died of elephantiasis. Among the seven cases of elephantiasis seen by Dr. Kinnis in the Mauritius,[281] three were Mozambique slaves, and could give no satisfactory account of their parentage. Of the remaining four—the first could give no history of her father and mother, but had brothers and sisters in perfect health: the ancestors of the second patient had not been affected with leprosy, but her husband had laboured under it for two years before death: the third case was a daughter of these parents, and one of her brothers had died of elephantiasis: the fourth patient appeared to have inherited the predisposition from the family of his maternal grandmother, who was never attacked herself, but who lost two sisters and three nieces by the disease. These and other similar data show that the predisposition to leprosy, like the predisposition to other hereditary diseases, may occasionally show itself only in one or two individual members of a family; and may sometimes lie dormant for one or two generations, to reappear in a subsequent one. “God and Nature,” says the reverend author of a description of the Faroe Isles, formerly quoted, “deals wonderfully with such people (lepers) in their marriages, for amongst the children, they beget some clean and some unclean. It has also been taken notice of that two living together in marriage, though the one be found infected, they live together as before, as long as one doth but murmur of it, till the magistrate doth separate them, and yet the sound remaineth uninfected; whereas another is often taken with the disease by a very little conversation.... What is this? but that God confirms the truth of his word, taking pleasure in them that live in a just wedlock, and wander in lawful ways, putting their hopes in him, that neither fire nor water, contagious disease, nor dangerous pestilence shall hurt them.”[282]
