Syphilitic and scorbutic taints appear in ulcers and abscesses. The helcoma resembles that of Aden: it generally attacks the legs and feet, the parts most distant from the centre of circulation; the toes fall of, and the limb becomes distorted. Phagædenic sores are most common amongst the poor and the slaves, who live on manioc, fruit, and salt shark often putrid. Large and painful phlegemonous abscesses, attacking the muscular tissue, occasion great constitutional disturbance: they heal, however, readily after suppuration. Scabies, yaws (Frambæsia), psoriasis, and ‘craw-craw,’ inveterate as that of Malabar or the Congo River, commonly result from personal uncleanliness, unwholesome food, and insufficient shelter and clothing. That frightful malady Lupus presents pitiable objects. The indigenous diseases which require mention are fevers, bowel- complaints, and pulmonary affections. Fevers at Zanzibar have been compared with Aaron’s rod; at times they seem to swallow up every other disease, and generally they cause the greatest amount of mortality. As at Muhamreh, and on the swampy margins of the Shat el Arab (Persian Gulf), the constitution worn out, and the equilibrium of the functions deranged by moist heat and sleeplessness, especially during and after the heavy rains of the S. West monsoon, thus relieve themselves. Persians and northern Asiatics are even more liable to attacks than Europeans; and, as in Egypt, rude health is rare. Some Indian Moslems have fled the country, believing themselves bewitched. Arabs born on the island, and the Banyans, who seldom suffer much from the fever, greatly dread its secondary symptoms. The ‘hummeh,’ or intermittent type, is remarkable for the virulence and persistency of the sequelæ, which the Arabs call ‘Nazlah’ (metastasis), or defluxion of humours—‘dropping into the hoofs’ as the grooms say. Cerebral and visceral complications, with derangements of the liver and spleen, produce obstinate diarrhœas, dysenteries, and a long dire cohort of diseases. Men of strong nervous diathesis escape with slight consequences in the shape of white hair, boils, bad toothaches, neuralgias, and sore tongues. The weak lose memory, or virility, or the use of a limb, the finger-joints especially being liable to stiffen; many become deaf or dim-sighted, not a few are subject to paralysis in its various forms, whilst others, tormented by hepatitis, constipation, and disorders of the bowels and of the digestive organs, never completely recover health. In this country all attribute to the moon at the ‘springs’ what we explain by coincidence and by the periodicity of disease. For months, and possibly for years, the symptoms recur so regularly that even Europeans will use evacuants and quinine two or three days before the new and full moons. In such cases, I repeat, change of climate is the best aid to natura curatrix.
