DeKalb, Ill., Nov. 22, 1906.
To the Editor:
—Your article on the "Migratory Needle" has just been noted. In one case, to my positive knowledge, a needle lay within the pericardial membrane and parallel to the heart, in a slaughtered beef. I had the specimen in my office for years. In another case the needle had transfixed the apex of the heart of a chicken, which, when killed, showed no sign of interference with the heart or the condition of the fowl. Nearly one-half the length of the needle had passed transversely through the apex of the heart. Reference can be given to those who made the discovery. In both instances the needles had doubtless been swallowed and had penetrated the tissues until they occupied the position as found.
