matter of the terms 'functional' and 'organic' we must walk very warily indeed. Is epilepsy a functional neurosis or an organic disease? Analogy suggests organic changes. No such changes have been constantly demonstrated by post mortem evidence; partly, of course, because post mortem examinations of cases of death in the epileptic or epileptiform condition have been extremely rare, and are not very common in cases where there is a well-authenticated history of attacks; but partly because our investigations into the minute anatomy of many morbid conditions are at present barred by the limitations of microscopic vision. We have no right whatever to assert dogmatically that there is no organic change in a tissue because we cannot see it under a magnification of 1000 diameters—though for a variety of reasons, which all pathologists will recognise, it is not altogether probable that a magnification of 10,000 diameters would in such cases demonstrate a constant change. In any case, if we are told by a spiritual or psychic healer that he cures cases of, let us say, old-standing chronic nephritis or cirrhosis of the liver by his own peculiar methods, our reply must be, not that this is impossible because we are dealing with organic disease, but rather that—
