Dr. Bross, a Jesuit missionary attached to the lazaretto at Trinidad, takes the ground that the disease in some way or other is transmissible. It is a well-established fact that when leprosy has once gained for itself a foothold in any locality, it is apt to remain there and spread. The case of the Sandwich Islands illustrates the danger. Forty years ago the disease did not exist there : now one-tenth of the inhabitants are lepers. — Dr. H. S. Piffard of New York in Medical Record, February, 1881.
