upper respiratory infection was followed by pneumococcus type VI meningitis. She was treated with sulfapyridine and anti-pneumococcus (rabbit) serum, type VI. Convalescence was uneventful but the rhinorrhea continued. Six months later she entered the hospital for surgical repair of cerebrospinal rhinorrhea. Examination revealed a normal appearing woman of 36 years. There was complete anosmia, slight pallor and blurring of the margins of the optic discs; the right pupil was a trifle larger than the left. Rhinorrhea was absent at the time of the examination. X-rays of

stated that this type of window had been installed in two rabbits. In the first animal the area became infected and the window dropped out in approximately five months. In the second rabbit the window was still in perfect position nine months following operation. The permanent windows of Sohler and his colleagues have been fabricated from lucite discs. These windows are screwed into skull defects by means of threaded, beveled edges. Two small holes are incorporated for the introduction and removal of fluids and gases. Optically polished surfaces enable the observer

disturbances of recent memory. The neurological status was essentially negative except for slight blurring of the right optic disc, complete absence of the abdominal reflexes, and generally overactive tendon reflexes. Laboratory Data . Roentgenograms of the skull ( Fig. 1 ) revealed a large calcified mass in the anterior portion of the right middle fossa which measured 5 × 6 centimeters in the anteroposterior projection and which appeared to originate from the lesser wing of the sphenoid bone. The mass was thought to represent a calcified meningioma. Fig. 1. Case

designed now the opening made is big enough for most ventriculographies. The taper on the drill causes it to lock and prevents plunging when the inner table is perforated. A Perforator. B Ball burr. (Actual size) Drill B is a modified ball burr which cuts with speed and with as much ease through the inner as the outer table. It is used to enlarge the opening made by A when a bone flap is being fashioned. It is also useful in starting the exposure for a disc as it bites well into the adjacent laminae. An extension of the ordinary Hudson drill handle

, “is now a healthy and normal child of five years of age.” Cushing's other important paper in 1905 related to palliative decompression for inaccessible brain tumors. 8 It had long been known, through the work of Horsley, Sänger and others, that an opening in the skull accompanied by incision of the dura in patients harboring a brain tumor would almost always relieve headaches and other pressure symptoms and preserve eyesight by allowing choked discs to subside. Heretofore, however, these operations had been performed, as a rule, either at the supposed site of the

satisfactory recovery, but in view of the presence of resistant staphylococci there is still a possibility of brain abscess. Case 4. On 17th July, right frontal wound and compound fracture of the left tibia from aerial bomb. Unconscious for a few minutes. Both wounds excised and left open. Sulphanilamide applied to wounds. Sulphadiazine, 9 gm. intravenously. 20th July (No. 4 Neurosurgical Unit): Temperature 99.4°F. Pulse rate 92. Slight blurring of right optic disc No other neurological signs.

effective hemostatic agent when used with weak solutions of thrombin while soluble cellulose is not hemostatic with thrombin solutions of the same concentration. 1 In the form supplied to us, soluble cellulose is not so readily broken up into fragments or cut to appropriate size as is fibrin foam. It is very advantageous to have the fibrin foam readily cut into discs, pellets or other shapes so that it may be readily applicable to the individual characteristics of the bleeding point at hand. Furthermore, the “permanent set” of the fibrin foam makes it retain the

September 19, 1924. The family history and past history were irrelevant. She had been quite well until 2½ months before entry, when she began to have severe frontal headaches. During the month preceding hospitalization the headaches had become more severe and had been associated with vomiting. Some dizziness accompanied the most severe headaches and in the month before admission she had difficulty in reading fine print. Physical examination at that time showed marked suboccipital tenderness and a definite cracked-pot sound. There was choking of both optic discs (6
