I may appear to have entered with unnecessary detail into this subject, but it is apparent that this fungoid skin disease, disseminated as it is by personal contact and other similar agencies, would have reached these sub-central Pacific Groups long ago if they had been occupied through ages by their present inhabitants. The same evidence, therefore, which can be brought forward to prove the recent appearance of this disease amongst the natives of these groups may also be advanced in support of the recent occupation of these islands by the eastern Polynesians.
From the previous remarks on the distribution of Tokelau Ringworm it may be inferred that in New Guinea and in the islands of the Malay Archipelago we have the home of the disease. From this region it has spread eastward towards the centre of the Pacific; and we may also infer that this eastward extension of the disease has occurred within the last three hundred years, since in the accounts which Gallego and Quiros give of the natives of the Solomon, Santa Cruz, and New Hebrides Groups at the time of their first discovery by the Spaniards, there is no reference to the prevalence of any cutaneous disease, which, if it had existed, would most certainly have attracted the notice of these early navigators.
I only had one opportunity of treating this affection, and that was in the person of a native of Guadalcanar, who was shipped on board as an interpreter, and who had been the subject of the disease for about five months. Partly from its obstinacy, and partly from the difficulty of ensuring that the remedies were regularly and thoroughly employed, my experience was not very satisfactory. Sulphur ointment, mercurial ointment, tincture of iodine, and a lotion of hyposulphite of soda (1 in 12) were severally used, and after about three weeks the skin was almost clean. Some weeks afterwards, the eruption re-appeared on the forearms in the form of the characteristic small circumscribed patches of body-ringworm. The local remedy, which I found most rapid in its effect as a parasiticide in the treatment of this case, was the tincture of iodine of which two applications completely removed the disease from the fore-arms. The lotion of the hyposulphite of soda and the mercurial ointment had apparently but little influence on the disease. The sulphur ointment, however, had a gradual curative action. To many of the vessels which leave Queensland and Fiji to recruit labour in the Solomon and New Hebrides groups, sulphur ointment is supplied; and the government-agents are instructed to use it in all cases of this disease amongst the natives recruited. I learned from some of these gentlemen that, when the remedy is applied thoroughly, and under superintendence, they usually succeed in thoroughly cleansing the skin from the eruption before the ships return to the colonies.
A pustular eruptive disease peculiar to children, which has been referred to by various authors as prevalent in the New Hebrides, Fiji, Tonga, and Samoa groups, affects many of the young children of the Solomon Islands, usually occurring about the age of five. A number of large papules, twice the size of a split pea, which subsequently become filled with a pustular fluid, appear on the face. These pustules by rupturing tend to unite and form unhealthy-looking sores of the size of a florin. The disease pursues a regular course of papule, pustule, and sore; and is said never to recur. As far as I could learn, the natives interfere but little with its progress; and, as in Fiji where it is known as coko,[162] they regard the disease as having a salutary influence on the future health of the child.

That peculiar spinal disease, which produces so many hunch-backs in the Society and Samoan groups, and which is so well described by Mr. Ellis in his “Polynesian Researches” (2nd edit., 1831, vol. iii. pp. 39, 40), does not prevail among the Solomon Islanders. I can only recall one instance of spinal deformity which came under my observation. It was in the person of a little boy about ten or eleven years old, who was the subject of lateral and posterior curvature of the spine. The little fellow, who was a native of Simbo, apparently experienced no inconvenience from the deformity, since a firm ankylosis had occurred. He was able to accompany me in my ascents to the summit of his island, which is elevated about 1,100 feet above the sea.
An epidemic catarrhal disease, which is allied to influenza, is very prevalent amongst the natives of these islands. It is commonly followed by lung-complications, which not infrequently cause the death of the sufferer. Such an epidemic in running through a village sometimes carries off several of the inhabitants. The elderly natives are, in fact, very liable to pulmonary affections; such diseases usually terminate their lives.
From the occurrence of an epidemic of this catarrhal disease, a village often obtains an unhealthy reputation; and the natives abandon it for some other situation, which is selected rather for the convenience of its position than for its freedom from unhealthy influences. A generation ago, one of the principal villages in the island of Ugi was situated on the level summit of a hill overlooking Selwyn Bay on the west coast, a site which would have at once been chosen both for its salubrity and for its capability of defence. However, a number of deaths occurred in the village from epidemic catarrhal disease; and the inhabitants shifted their homes to the low-lying unhealthy situation where the village of Ete-ete now stands.
Epidemics of mumps occur occasionally amongst these islanders. In October, 1882, whilst we were taking to Ugi the crew of the “Pioneer,” a schooner which had been wrecked off the coast of Guadalcanar, some cases of this disease appeared among the natives belonging to that ship, affecting ten out of the twenty on board, and pursuing its usual course. It was evident that the disease had been originally brought from Brisbane, as the ship which was engaged in returning natives from the Queensland plantations, had had three cases previously, the first having occurred on her arrival at Makira harbour, just a week after she left Brisbane. That mumps is sometimes a fatal disease amongst these races, there is no reason to doubt. Mr. Stephens of Ugi informed me that a few years since, some natives of Lord Howe Islands, whom he was employing on his premises, rapidly succumbed to this disease.
