    tries—Wales, Germany, Netherlands, Belgium, France, and Spain—the infection is wholly or chiefly confined to mines, and is found in but few definite localities; in at least 46 of these countries the infection is general and widespread. Tabular statement on page 86 shows that these 46 countries comprise an area of about 14,464,158 square miles and have a population of about 919,858,243. To this we may add 11 of our own States, with an area of 510,149 square miles and a population of 20,785,777. Of the total population of. the globe—about 1,600,000,000 people in round numbers— about 940,000,000 live in countries where hookworm disease is prevalent. | b. Degree of infection—In many countries the infection is extremely prevalent. In 1904 it was estimated that 90 out of every 100 of the working population of Porto Rico were infected. My own observations in the island con- vince me that this estimate was not excessive. The reports summarized in Publication No. 6 estimate: That of the whole population of Colombia living between sea-level and 3,000 feet above, 9o per cent are infected, and this includes the great majority of the 5,000,000 of people living in this country; that of the total population of British Guiana, 50 per cent are infected, the percentage of infection among the laborers on the sugar estates being much greater; that in Dutch Guiana the infection on many plantations runs as high as go per cent; that over a thousand microscopic ex- aminations in French Guiana showed an infection of 35 per cent among a local population, 50 per cent among soldiers, and from 50 to 88 per cent among prisoners; that in Egypt general estimate places the infection at 50 per cent of the laboring population; that 50 per cent of the coolie laborers
