Physicians have no professional interest in the tariff, but when the subject of tariff revision comes up there are several schedules in regard to which medical men of right have definite convictions. The duties on scientific instruments and books stand first in importance. The following duties of the present tariff were listed recently in a newspaper and are worth attention: Boric acid, 122 per cent. In 1904 $30,000 worth was imported, paying $36,000 in duty. Tannic acid, 103 per cent.; spirits of nitrous ether, 250 per cent.; sulphuric ether, 236 per cent.; spectacles and eye glasses, higher grades, 50 to 70 per cent., and cheaper grades, 116 per cent. Physicians will not protest because firecrackers pay 126 per cent. duty, even though the imports in 1904 were $266,000 and the duty $334,000.
