Finally, as a general routine treatment, it is advisable to keep at the factory some form of mixture containing iron, which may be given to those persons who are showing signs of slight anæmia, generally associated with some degree of constipation, and it is therefore better to use a form of iron cathartic. This medicine should also be kept in the care of the foreman, who will see that it is administered to the men properly. In this way any persons who at the weekly examination exhibit signs of anæmia may be promptly treated, and what is more, the surgeon is assured that the workmen in question actually obtain the medicine prescribed regularly. During the routine weekly or monthly examination, or at whatever intervals the medical examination takes place, particular attention should be paid to the records kept of the state of health of the various persons, and whenever possible alteration of employment should always be enjoined when early signs of anæmia make their appearance. The surgeon should spare no pains to determine if any of the workmen are confirmed alcoholics, and such persons should be removed from work in dangerous processes, while at the same time care should also be taken to eliminate any persons suffering from those diseases which are known to be predisposing causes of lead poisoning. The card system of registration of any symptoms noted or treatment given facilitates supervision of the health of the men. In times of stress where some particularly dangerous process is in operation, as, for instance, where portions of a building which has become thoroughly impregnated with lead dust is being pulled down, or where machines are being altered, removed, or rebuilt, especial care should be exercised with the workmen so employed, and it is advisable in such cases to adopt preventive measures on the supposition--generally correct--that such persons are absorbing a larger quantity of lead owing to their peculiarly dusty employment than they were under normal circumstances. At such times, also, it may be advisable to administer some form of mild iron cathartic to all persons employed in the factory for, say, a week at a time. It must not be supposed, however, that these methods of treatment in any way supersede the precautions for the prevention of lead poisoning by mechanical and hygienic means; they are merely additional precautions which may be put in force under special circumstances. =The Treatment of Lead Poisoning.=--The treatment of definite lead poisoning, as the treatment of lead absorption, is directed towards the elimination of the poison, the promotion of repair to the damaged tissues, and special treatment directed towards those special organs which suffer mostly in lead poisoning. At the same time, special treatment of urgent symptoms may be called for; but in the treatment of the urgent symptoms the fact of the general elimination of the poison must not be lost sight of.
