There have been generally in the Philippines a few successful medical practitioners from Europe. Foreigners are allowed to exercise their profession, having previously obtained the authority of the Spanish Government; but the natives seldom look beyond their own simple mode of dealing with the common diseases of the islands; and in those parts where there is little or no Spanish population, no one is to be found to whom a surgical operation could safely be intrusted. The vegetable world furnishes a great variety of medicinal herbs, which the instinct or the experience of the Indian has turned to account, and which are, probably, on the whole, as efficacious as the more potent mineral remedies employed by European science. Quinine, opium, mercury, and arsenic, are the wonder-workers in the field of Oriental disease, and their early and proper application generally arrests the progress of malady.
I found practising in the island of Panay Dr. Lefevre, whom I had known in Egypt more than twenty years before, and who was one of the courageous men who boldly grappled with the current superstitions respecting the contagious character of the Oriental plague, and the delusions as to the efficacy of quarantine regulations, so really useless, costly, and vexatious. He placed in my hand some observations which he had published at Bombay in 1840, where vessels from the Red Sea were subjected to sanatory visitations. He asserts that plague is only generated at particular seasons, in certain definable conditions of the atmosphere, and when miasma is created by the decomposition of decaying matter; that endemic plague is unknown in countries where proper attention is paid to hygienic precautions; that severe cold or intense heat equally arrests the progress of the plague; that the epoch of its ravages is always one when damp and exposed animal and vegetable substances emit the greatest amount of noxious gases; and that plague has never been known to originate or to spread where the air is in a state of purity. I was glad to rediscuss the matter with him after so long an added experience, and to find he had been more and more confirmed in his former conclusions by prolonged residence in the tropics, where endemic and epidemic diseases partake of the pestilential character, though they do not assume the forms, of the Levant plague. Dr. Lefevre affirms that quarantines have done nothing whatever to lessen the dangers or check the ravages of the plague, but much to encourage its propagation. He complains of the deafness and incredulity of those whom the examination of a "thousand indisputable facts" will not convince, and he thus concludes:--"If I had not with peculiar attention studied the plague in the midst of an epidemic, and without any more precautions than if the danger was nothing--if, subsequent to the terrible visitation of 1835 in Egypt, I had not been frequently a witness to the scourge--if, finally, since that epoch I had not given myself up, with all the warmth of passion, to the constant study of this malady, to the perusal of histories of the plagues which have ravaged the world, and to the examination of all sorts of objections--I should not have dared to emit such a decided opinion--an opinion respecting the soundness of which I do not entertain the slightest doubt."
