Frequent use of central venous lines has led to an increasing problem with embolized catheter fragments which have become lodged in the right heart and pulmonary vasculature. Removal of catheter fragments is justified because of a high complication rate when they are left in situ. Using a snare retrieval apparatus catheter fragments may be quickly and easily removed. In the past year we have seen 3 patients with embolized catheter fragments. One case was unusual in that its transverse position in the pulmonary vasculature required initial dislodgement with a pigtail catheter before it could be successfully snared. The literature and our experience suggest that most, if not all, catheter fragments in the right heart and pulmonary circulation can be successfully retrieved without resorting to thoracotomy.

IN 1908 Pearson discussed the pedigree of a certain Lobster-Claw or Split-Foot Family in this Journal *. Pearson's information was obtaitued from several members of the family, but his photographs and skiagrams were of one particular section of it. McMullan, unacquainted with Pearson's paper, read a paper on the same family before the Reading Pathological Society in 1910. He worked principally with a (lifferent section of the family and his photographs and skiagrams did not cover the same individuals as Pearson's. Hearing of the latter's paper, McMullan placed his material at the disposal of the Editor of this Journal and the present supplementary metnoir is the result. During the five years that have intervened since the first paper several additions have been made by birth to the family; thus while Pearson dealt with 25 deformed individuals the present account contains 33t. Further, somewhat fuller particulars have been found of the two earliest generations. The order of birth of Generation III. and further the total number of brothers and sisters were given differently by different members of the family to Pearson and to McMullan. These discrepancies led Pearson to make some investigation into the church registers, but they disclosed a rather chaotic state of affairs. Some facts, however, resulted. Ann J. (II. 3) was married to Francis S. (II. 4), at N. in the Chilterns in 1837, both being utnable to sign their names. It was supposed that III. 2, 3 and 5 were born before the S.'s migrated to W. The names of most of the othier children in Generation III. are to be found at about the proper dates in the baptismal register of W. BtLt not until the birth of John S. (III. 13), who mnust have died under two years of *

A patient with Burkitt's lymphoma developed acute leukemia. Complete remission was achieved with combination chemotherapy. This report suggests that a fatalistic outlook is unwarranted when leukemia develops in patients with Burkitt's lymphoma.
