kittle more than comment on their significant The physiology of the dural venous sinuses, and the way in which the venous blood-flow is protected from the aspiratory effects of inspiration is elucidated. Next in order are treated the etiology and pathology of sinus phlebitis, and its semiology and diagnosis ; an excellent resume of the most modern therapeutic technique is furnished in a final chapter of some 60 pages. Among useful practical matter is the ’description of the Queckenstedt phenomenon as . adopted for diagnosis of unilateral sinus thrombosis ; the account of the neural complications of the condition is in some respects inadequate (for instance, that of the syndrome of the superior longitudinal sinus), and the data (clinical and spinal fluid) for differentiation from meningitis. The bibliographical ,references are largely confined to German and American sources. -

bar-parlour mantelpiece) on the mornOne Saturday morning he took his usual dose, complained of its bitter taste, went into convulsions, and died. His medical attendant, Dr. F. C. Carle, diagnosed recent strychnine poisoning, and with great promptness took possession of the bottle of salts, glass and spoon used by the dead man ; he also discovered some spilt crystals on the barparlour floor. All these articles were eventually found to contain traces of strychnine, and the evidence of Sir Bernard Spilsbury and Mr. John Webster left no doubt of the cause of death. Vaquier, who had been early in the bar-parlour that day, had bought strychnine in London "for wireless experiments"; while in prison he revealed the hiding-place of a further supply of the poison in a toolshed in the hotel garden. He tried to implicate a mysterious third party, and the main feature of his defence was a vigorous attack on the credibility of Mrs. Jones ; but there was no doubt of the verdict, and he was hanged in August, only a few months after he first met her. on

News Inventions. ETHER INHALER. THE ether inhaler here illustrated has for its basis ’the principle of a vapour space which is obtained by superimposing an outer wire gauze cage on a Schimmelbusch face-piece. The gauze is perforated at short ;intervals, and when in use is covered with one or two layers of lint held in position by a spring. The outer

Among the advantages of this inhaler are ease and uniformity of anaesthesia, clear view of the face during anaesthesia, and economy in

use.

I would like to thank Dr. Z. Mennell, senior visiting anaesthetist, and Dr. G. Edwards, senior resident anaesthetist, of St. Thomas’s Hospital, for testing the inhaler and for their very helpful suggestions. The mask is made by Messrs. Down Bros., Ltd., St.
