certainly it is our duty to enlarge to any extent on the terrors of the 
tertiaries. 
There is no necessity for special yaws asylums, but it is very 
desirable to have some provision for hospital treatment of severe and 
cachetic cases. Special wards in a general hospital would meet the 
requirements. 
In the local treatment of yaws, I have obtained best results from 
a paint of zinc oxide and calamine, an old-fashioned but ever-useful 
preparation. It is readily applied by the patient or his parents; it 
is not easily wiped off, and, most important of all, it keeps the 
frambesia dry. I feel confident that a case of yaws is not very likely 
to infect other persons from his skin lesions as long as the frambesiae 
are kept dry and well coated with this paint. The risk of tonsillar 
infection from spoons and cups cannot, of course, be avoided in the 
peasant class, and that this is a frequent mode of infection with 
syphilis is well recognised. 1 But the most important material of 
infection in yaws is the secretion of the frambesia, and this can be 
limited by local applications, and by' causing the absorption of the 
papilloma as rapidly as possible with mercury internally.
