" From the foregoing remarks it will be gathered, that between 

 these symptoms and the ordinary course of specific disease there 

 are many points of similarity. Before proceeding further it is 

 well to state that I was unable to find any venereal disease 

 amongst the natives ; in fact, disease the result of intercourse 

 seemed unknown. Yet though, in the disease called " tonna," 

 there was no point observable of primary inoculation, many of 

 the symptoms are allied to those noticed in the course of a 

 syphilitic history ; thus the pustular symptom is similar to the 

 secondary rash of syphilis, the ulcerative process apt to follow 

 the above lesion might be said to correspond to the reminder or 

 early tertiary stages, while the periosteal nodes and the ulcerative 

 process of the nasal cartilages would be the tertiary stage. This 

 comparison of course presumes that the periosteal condition, <kc., 

 is a direct result or sequence of the early pustular disease. And 

 in support of this presumption it may be added, that in all 

 patients who had these periosteal manifestations that there were 

 indications or history of tonna. On the other hand, it may be 

 said that most natives have had tonna. 



" Ordinary care and protection much improved the pustular or 

 early ulcerative state, and specific remedies were most efficacious 

 in ulcerative and periosteal conditions. 



" Several cases of permanent blindness among the natives had 

 been caused by Keratites and Irites. One case of Irites develop- 

 ing in a lad of eighteen from no apparent cause, was effectually 

 cured by atropine solution locally supplied, with two grains of 

 mercury and chalk given twice a day for a fortnight."
