The same precautions are necessary in using the axis traction as the ordinary forceps. Especially must it be remembered that, as the force is exerted directly in the axis of the pelvic curve, and none being lost, much less is required, and generally the force of one hand is quite sufficient. To avoid too great compression of the head, the compressing force should be removed by opening the lock in the interval of each traction. Breus' forceps, after being tested successfully in all possible difficult cases—in many where the operator had failed with the ordinary forceps, as I myself have seen—is now recognized as the instrument best adapted to those cases where the head presents high above the pelvic brim. CORRESPONDENCE. BALTIMORE NOTES. BY SPENCER M. FREE, A. M., M. D., Professor of Diseases of Children in the Baltimore Polyclinic, Baltimore, Md. It is said of Baltimore that socially it is different from other large cities in the _freedom_ as well as the cordiality with which it extends its hospitality. The business men and their clerks are polite and attentive. They do not display the trait, so common in the metropolis, of incognizance—even to rudeness—if one chances to be on a tour of inspection instead of purchase. The impression is at once made, and very forcibly, that a Baltimorean has plenty of time, that he is not hurried. He will stop on the street and direct a discomfited stranger, and has been frequently known to turn aside from his duties and accompany the lost one to where he could take care of himself. This is a natural element in the entire populace, and is very prominent in the medical profession. A stranger is welcomed so heartily that he feels at home immediately, and can settle down among friends.
