For the rest, the whole of Egypt up to this latitude may be said to be very healthy for Europeans, there being much less malaria than one would be inclined to expect as a consequence of the annual overflowing of the Nile; a circumstance which may, I believe, be attributed to the generally neat character of the cultivation, and the care with which every square yard of cultivable soil is utilised. Internal worms are, however, extremely common amongst the natives, but care in the matter of drinking water will render the risk run by the European very trifling. Another terribly common disease amongst the natives is granular ophthalmia, a disease easily acquired by contact, or indirectly through the agency of flies, but Dr. Sandwith finds that it is extremely rarely taken by Europeans, though soreness of the eyes from dust and glare is not uncommon, for which he recommends the daily use of a little boracic solution as a toilet wash. It might, however, be perhaps advisable to protect young children by means of a veil when abroad, especially when entrusted to the care of a native attendant. _THE REMAINDER OF THE AFRICAN CONTINENT._--Our knowledge of African meteorology is necessarily in its infancy, and it is only possible to furnish a few tables of widely distant parts of this immense area, which may give some idea of its climatic characters. The whole of the northern part of the continent is extremely dry, much of it being quite rainless, especially towards its eastern side. Following on this is the equatorial belt, a great portion of which is barely, if at all, explored, but which seems to usually present the general characters of such latitudes and to be usually blessed with an ample rainfall across the entire width of the continent. Southward of the equatorial zone we again meet with immense dry and desert areas, such as the Karoo, but here it is the western side that is the more arid, none of the south-eastern coast being in any sense rainless. Malaria is extremely rife in almost all parts of the huge peninsula, and in addition to this we have in “Blackwater fever” and sleeping sickness, diseases which seem to be at present its own peculiar privilege, though, fortunately, yellow fever is not as yet included in its list of dangers. The low-lying country along the coast and of the great rivers is notoriously unhealthy, such as the Bight of Benin, where, according to the sailor’s proverb, “There’s two comes out Where three goes in.” But inland there are considerable tracts of elevated country which present climates by no means to be despised, and which will no doubt in time, with the advance of civilisation, become eligible and healthy sites for European occupation, and more than one example of climatic conditions that appear decidedly inviting will be found amongst the tables furnished below.
