The fact that there are 24,000 to 30,000 lepers in Colombia-that is, as many lepers as there are in the rest of South America, the Sand- wich Islands, North America, and Europe together-should give that country a pre-eminent importance in the eyes of leprologists. There is no proof that the disease existed in Colombia before the invasion. Why should it prosper there and not in Peru? The only essential difference between the two countries seems to be one of climate. But there is one circumstance which might throw some light on this singu- lar difference. Colombia, New Granada, Venezuela, etc., are coun- tries where insect life is extremely abundant, and very probably pes- tilential, carrying poisons to the human organism with which they come into contact. Cases of leprosy are more numerous in the river valleys, where the air is loaded with moisture, and becomes an enormous stimulant to the production and development of insect life. Such valleys are more fre- quently found and more densely populated in Colombia than in Peru. They are occupied by a low class mixed race of Spaniards, negroes, and Indians. The better class, the agricultural part of the nation, occupy the templados, 6000 to 8000 feet above the sea-level; the wealthiest part live still higher up above the templados, on the pomu- ros. The disease develops in climates which vary 140 to 20°, generally humid, and very sparely lashed by winds. An Extremely Interesting Particularity about Leprosy in Costa Rica. Dr. Emilio Echeverria, of San Jose, writes me that all cases of leprosy in that country, which came to his knowledge, were of the anesthetic variety, with one exception, that of an old negro, who brought the disease from his native Jamaica; he had lepra tuberosa. He adds that, to his knowledge, there is no physician in Costa Rica who has seen original tubercular leprosy in that republic. Dr. Eche- verria adds that he is pretty sure that this case of tuberosa was the only tubercular case ever observed in Costa Rica. This anesthetic leprosy, considered by Dr. Echeverria as post- Columbian, is gaining ground rapidly in that part of the world, although it would be too much, so far, to call it widespread. 2 Albert S. Ashmead. History of Leprosy in Cuba. Dr. D. Enrique: Robeein writes: "In all America leprosy has been imported ; the Indians never knew this scourge until the first con- querors reached its shores. We may extend this assertion to all the Antilles, including Cuba. Not having existed ab ovo, we cannot well assert that leprosy has always existed in Cuba. " The disease begins to be known at the time of the colonizations which proves that lepra is inherent to men, and that it always follow, human currents. " Are there statistics on which we can found the relations between the number of lepers existing in the divers epochs up to our own days ? Unfortunately they do not exist: nothing has been done in Cuba to obtain such information. The director of the leper hospital of Havana could not give me these statistics. And if for one asylum there are no data, what can we expect from the province of Havana and the whole island ? In a country eminently leprous like ours, in which the two leper races, Africans and Asiatics, are largely represented, this negli- gence is incomprehensible. It is more than probable that in Cuba leprosy has spread as it has in other countries. To-day, even in our own capital, the lepers are numerous. We speak of those we see ; and those who hide, how many are they ?" Albert S. Ashmead, M.D. New York.
