Our gratitude to him and to his successors is a little tinged with envy when we turn at the end of this volume to the Collection of incunabula and early medical prints " to find nearly 500 books printed before A.D. 1500 and half as many again from the next quarter-century, with prize upon prize among them. But what more fitting reward could there be for the bibliographers to whom we are so much indebted No subject has been so well treated as bibliographically medicine, and now we learn that our luck will hold. It was rumoured that the end of the third series was to be the end of the IndexCatalogue, and that after 1926, the last year yet indexed, the deluge would be over us. Now we learn with real gratitude that "work on the fourth series will be begun at once." Dr. Billings lies in the grave, but his great catalogue goes marching on.
after operation might show that deficient intake of essential substances played a part. Meat and green vegetables, so essential to normal hsemopoiesis, are too often lacking from the menu of the gastric patient. It is obvious that prolonged study of a large series of post-operative gastric cases would be of great interest. Biochemical investigations of the blood, the gastric juice, and the faeces should be correlated with the heamatological picture and the dietary

THE ÆTIOLOGY OF OSTEITIS DEFORMANS
Dr. T. J. O’Reilly and Mr. Joseph Race, F.I.C.,l have investigated 30 cases of Paget’s disease which found their way, with a diagnosis of rheumatism, to the Hospital for Rheumatic Diseases in Buxton. Forty per cent. of them showed the physical signs of osteitis deformans ; 33 per cent. had the symptoms but none of the physical signs ; and 27 per cent. had neither symptoms nor signs, the condition being accidentally revealed by radiography. In the first ANÆMIA AFTER GASTRIC OPERATIONS group the average duration was seven years, and in THERE is apparently no gastro-intestinal disorder the second group four years ; the pelvis was affected that may not be associated with anaemia, and evidence in 26 cases and the lumbar spine in 24, while the femur is accumulating to suggest that this association is and tibia were both affected more often than the skull. no mere coincidence.
