There are quite a number of lepers in San Francisco, many more than the eighteen or nineteen who are at present in the pest-house. The important question, however, before the city itself and before the United States is whether San Francisco and the Pacific Coast is merely a temporary abiding place for a few lepers who have come to it by accident, or whether this part of the United States is really becoming a leper focus where the disease may be contracted.
The difference between these two conditions is very great. London, Paris and Berlin, for instance, have always a number of lepers who have come to them either as returned officials or merchants who have acquired their disease in a leper country, such as Tonquin or India, or as patients seeking medical advice, but it is not considered that any of these cities constitute leper centers where leprosy is
