The treatment of the hookworm disease is simple, and the donation by Mr. Rockefeller of $2,000,000 is intended to be sufficient to furnish the opportunity at least for a complete cure of all the cases. It has been found that a small dose of a preparation of thyme known as thymol stupefies the parasites with which it comes in contact, so that they unloose their claws and are set free in the intestine after its use. A dose of epsom salts shortly after clears them out, and except for the loss of blood, the disease is finished. Sometimes, however, in long-continued cases the worms have penetrated so far into the membrane that the use of thymol cannot withdraw them. In fact, in autopsies, it has been found necessary to take tweezers and to use considerable force in order to pull them out. The prevention of the disease is really the cure of the disease, an apparently simple matter, as already described. An improvement of sanitary conditions so as to make impossible further pollution of the soil should be also undertaken. Wherever the disease has prevailed in this country or in Europe, it has been because of an utter neglect and disregard of what are now known as ordinary sanitary conveniences, and the report of the Country Life Commission, although many charges were made against the conditions of living in different parts of the country, was far from telling the whole story in the matter of the shortcomings in parts of the southern states. There is, therefore, every reason why the farmer and others living in the country should be urged to make themselves comfortable with all known modern sanitary appliances. This is desirable, first, for the sake of others on whom their sins of unhygienic living might be visited, and then for their own sake, because there such sins would also have an effect to a degree tenfold more severe. _Pellagra._ Another disease peculiar to country life, and which has only within the last few years been recognized, is known as pellagra. Not yet is it even known through what agency the disease is transmitted, but it has been beyond question established that in some way corn is responsible for its spread. Apparently, spoiled corn is necessary, and while presumably the corn itself is not the agent, the parasite or organism that is responsible lives only on corn which has been spoiled. Scientists have long worked on the disease, and it would be a merely speculative pursuit, one of interest to scientists and medical men only, except for the fact that within the last few years it has broken out in this country and is increasing to a most alarming degree. The disease itself is almost hopeless when once established, physicians being yet utterly unable to grapple with it; and while in Italy, Spain, and Egypt it has been known for a century, there is still a death-rate of over 60 per cent, and these deaths occur after most horrible suffering and agony.
