revolts at the idea of the oil; we must then try other fats; and we should go on trying one thing after another--butter, plain cream, Devonshire cream, even olive or cocoanut oil (though these are the poorest things of the sort we can use)--till we get the patient well into the way of taking a considerable, if possible a decidedly large, daily allowance of fat, without provoking dyspepsia. It is surprising what can be done in this way by perseverance and tact, and it is no less striking to observe the good effects of the treatment. Nothing is more singular than to see a girl, who was a peevish, fanciful, and really very suffering migraineuse, brought to a state in which she will eat spoonful after spoonful of Devonshire cream, and at the same time lose her headaches, lose her sickness, and develop the appetite of a day-laborer; and, though such very marked instances as this are uncommon, they do sometimes occur, and a minor but still important degree of improvement is very frequent. As for the _modus operandi_ of the fatty food, there is no certainty. Dr. Radcliffe believe it acts as a direct nutrient of the nervous centres; and I also cannot help feeling that there is some evidence in favor of this idea. But, whether this be so or not, there is another kind of action of fat that is more simple and obvious; namely, it seems to be certain that the enrichment of the diet by fat greatly assists the assimilation of food in general, and thus the patient's nutrition is altogether improved. It is not merely, however, by increasing any one element of food that we should seek to enrich the diet of neuralgics, but rather by such a steady and persistent effort as Dr. Blandford describes, to increase the total quantity of nutriment to perhaps as much as one-third more than the patient would probably have taken in health. To those who from prejudice are incredulous of the propriety of this method, I would say, "Try it, and I venture to say your incredulity will disappear." More especially I would urge the great importance of this system in modifying the nervous status of very young, and also of aged, sufferers from neuralgia; it is the indispensable basis of a sound treatment for such patients.
