In the Philosophical Transactions there is a case related of a woman whose fancies were not quite so solid, and who used to gratify her aerial appetites by putting the nozle of a bellows down her throat, and blowing away until she was tired. These longings of parturient women are most common; but it is rather curious, that, among our negroes in the West Indies, the husbands pretend to long for their wives, and endeavour to gratify them by proxy. Possibly such might have been the fancy of Cambes, the Lydian prince, who, according to Aelian, took it into his head one night to eat up his beloved wife. CAUSES OF INSANITY. Madness is attributed to moral and physical causes. Physicians do not agree as to the prevalence of either of these sources of human misery. Some of them, most unjustly accused of materialism, seem to lean to the opinion that, generally speaking, physical causes can be traced in _post mortem_ examination; while others, equally skilled in accurate anatomical investigations, maintain that these organic derangements are very seldom met with. Lawrence affirms that he had "examined after death the heads of many insane persons, and had hardly seen a single brain which did not exhibit obvious marks of disease;" and he further states, "that he feels convinced from his own experience, that very few heads of persons dying deranged will be examined after death without showing diseased structure, or evident signs of increased vascular activity." The celebrated Morgagni gives similar results of his extensive dissections. Meckel and Jones are of the same opinion. However, Pinel, whose anatomical pursuits on the subject were most extensive, clearly declares that he never met with any other appearance within the cavity of the skull than are observable in opening the bodies of persons who have died of apoplexy, epilepsy, nervous fevers and convulsions. Haslam, whose experience in this matter was also very great, asserts that nothing decisive can be obtained in reference to insanity from any variations of appearance that have hitherto been detected in the brain. Greding observed in two hundred and sixteen maniacal cases which he examined, the whole of whom died of disorders unconnected with their mental ailments, that three of the heads were exceedingly large, two exceedingly small; some of the skull bones were extremely thick, others peculiarly thin; in some the frontal bones were small and contracted, in others the temporal bones compressed and narrow.
