the same wound. These pins were all of the same length, each measuring -f- of 

 an inch. The wound at which these pins were discharged was on the superior 

 part of the scapula. After the girl had received her cure, and was discharged 

 from the infirmary, which happened Sept. 4, Dr. L. compared her shoulder with 

 Cowper's Anatomical Tables on the Muscles; and, as near as he could guess, 

 the wound was on the fleshy belly of the trapesius. And yet the pain in the 

 patient's side attended her as long as the pins remained in the wound, but left 

 her soon after they were discharged, as did also her cough, and spitting of blood. 

 Being obliged to lead a sedentary life in the infirmary, and to keep herself as 

 quiet as possible, her catamenia left her; but her spitting of blood could not 

 be attributed to that defect, because she was very regular before her admission, 

 and yet she had spit blood from the time the pins were removed from the oeso- 

 phagus, which was some months before she came to the infirmary. 



It would be matter of considerable satisfaction, could the exact course be as- 

 certained which was taken by these pins, in their passage from the oesophagus to 

 their exit at the left shoulder. From the cough and spitting of blood one shoukl 

 suppose that the lungs were injured by them. From the pain under the false 

 ribs, it may be imagined that the diaphragm was aflected. And yet from their 

 being discharged at the shoulder it may be presumed, that neither of these parts 

 were ever wounded ; but that the pins, being forced through the substance of the 

 oesophagus into the muscles of the neck and shoulder, passed thence to the part 

 whence they were discharged. 



Since Dr. L. drew out the above account, he had seen a case nearly similar to 

 it, recorded in the Phil. Trans., N°46l. A small needle being lodged in a wo- 

 man's left arm, about 6 inches below the shoulder, passed thence to her right 

 breast, whence it was extracted many months after it first entered the body. 

 About a month after the accident, she felt a pain above the place where the 

 needle ran in, which extended up her shoulder. It lasted there 3 or 4 days, and 

 then returned by fits. About 17 weeks before the needle was extracted, she felt 

 a pain at her stomach, was sick, and had retchings to vomit. These symptoms 

 continued to afflict her, especially in the morning, until within 2 days of the 

 needle being extracted, at which time she thought a pin had got into her right 

 ireast. This directed the surgeon to make an opening there, and he extracted 

 the same needle that had entered at her arm from the part where the pricking 

 pain was; after which she had never any return of pain in her breast, stomach, 

 shoulder, or arm.
