70 FUNAFUTI ATOLL. 



whose results I was most gratified, was an ointment in great 

 request among the natives : 



Chrysophanic acid ... ... 2 drachms 



Liquor picis ligni ... ... 2 ounces 



Carbolic acid ... ... ... 20 drops 



Beeswax... ... ... ... 2 J drachms 



Clarified Lard ... 1 pound 



There is little doubt that the essential element in killing the 

 parasite is the Chrysophanic Acid, and the Liquor picis ligni 

 diminishes the tendency to inflammation which is apt to be 

 caused by the Chrysophanic Acid. The latter also gives a 

 pleasant smell which is congenial to the native. 



" After constant application for a fortnight one case was cured 

 by this prescription : 



Ammonia chloride of mercury... 1 ounce 

 Liquor picis ligni ... ... 1 ounce 



Beeswax ... ... ... ... 2 ounces 



Clarified lard ... ... ... 1 pound 



"Tonna.* There is a disease called Tonna, which consists of a 

 scattered pustular eruption attacking the face, neck, trunk and 

 limbs of children between one and three years of age. In severe 

 cases it lasts from three to eighteen months, during which time 

 the general health of the child seems to be deficient. The com- 

 paratively healthy skin between the pustules is dull, dry, and 

 has, as a rule, lost its smooth soft state. In severe cases the 

 pustules, through dirt, neglect, and unhealthiness of constitution, 

 are apt to break down into an ulcerative process causing cicatrical 

 contraction in healing. 



" In a few cases this ulcerative condition and its results are seen 

 in adults, and, when attacking the face and neck, causes much 

 disfigurement, exposing the mucous surface of the eyelids, lips, &c , 

 and in one case, if not fixing the head in an immobile position, at 

 least rendering considerable diminution in movement. 



" Amongst the adult population, besides the above described 

 conditions, periosteal enlargement of the tibia and arm bones 

 occur, which is occasionally accompanied with pyrexial attacks 

 lasting for a few days, when increased pain and tenderness over 

 the nodular masses is experienced. 



" Again, a similar ulcerative process that attacks the skin, takes 

 place in the mucous membrane, bones and cartilage of the nose 

 and larynx, causing a marked flattening of the nose. 



* Compare H. S. Cooper Coral Lands, ii., 1880, p. 73. The Tongans 

 knew this disease by the same name in the first decade of the century,
