use the circulation of the congested brain is much relieved. In confirmed cases of arteriosclerosis of the brain, however, snuffing should be avoided, for it may have fatal results. Excessive snuffing is also deleterious to healthy men, especially when tobacco is used. To prevent apoplexy the hygienic advice we have given in the beginning of this chapter to avoid high blood-pressure must strictly be followed. I should like to add to them hot foot-baths for about five minutes, to which mustard powder could be added. There should also be a special care for a wise diet, avoiding constipation; of meat only very little should be taken, fish should be preferred, and of meat only chicken and veal allowed. The best food against arteriosclerosis and heart trouble consists of a milk and egg diet, with vegetables and fruit, to which fish and cheese may be added. As a most valuable food for overwork of the heart and the general circulation, I recommend honey, whose merits I show in next chapter. THE BEST FOOD FOR A FAILING HEART. There is one muscle in our body that never takes a rest. It never ceases to work, either day or night, and the better for us, for if it should stop it would mean the end of life. This muscle is the heart. Of course we must feed well such a hard-working organ, and have special care to select such a food that is the most genial for it and can the best promote its activity. As the heart is a muscle we must give the food that is best indicated for muscular activity. Observations have shown that the muscles of our body are doing their work at the expense of a certain sweet stuff (glycogen) contained in them. Experiments also prove this, for it has been found that the heart of animals removed from the body will survive for days the death of their owner if kept in a salt solution, with grape- or fruit-sugar added. The addition of certain mineral salts like lime and carbonate of sodium is also able to prolong the survival of the cut-out heart of dead animals. So there can be no doubt that the same elements must also prove useful to the heart of the living, as is indeed the case.
