1845 the blood and if the period of decompression is too short the gas is disengaged as bubbles in the capillaries and tissue spaces, with the result that embolism of a vessel may occur. The experiments confirm the conclusions of H. Hersent of Bordeaux and others which indicate clearly the danger connected with short decompression periods. Every death or case of paralysis from air embolism must be set down to the negligence of the contractor in not insisting upon a sufficient length of time for decompression. Mr. Hill and Mr. Greenwood have placed on record the subjective changes which they experienced during the progress of their work. They found that apart from changes in the voice and anaesthesia of the lip, the subjective effects of increased pressure depended upon psychical conditions such as anxiety and excitement. I One of the investigators had not practised beforehand the opening of the Eustachian tubes and accordingly was moat distuibed at the first experiment. The sensations of increasing deafness and intolerable discomfort in the ears with no obvious cause and the iuability togain relief by the recognised method of swallowing produced a condition of mental distress which led him to terminate abruptly the experiment. Bat after learning the method of cpening the Eustachian tubes the trouble did not occur in subsequent experiments. The investigation al o showed that changes in the percentage of carbon dioxide in the alveolar air are due solely to physical variations and not any increase or diminution in the respiratory metabolism ; and further, that, contrary to Snell’s opinion, the presence of carbon dioxide in the respired air does not exercise a pecularly unfavourable influence under high pressures.

MIXTURE.

IT has recently bfen shown by Mr. J. Rutherford Hill in the Pharmaceutical JL1lrnal that the solution of strychnine hydrochloride of the 1898 British Pharmacopeeia is incompatible with solutions of magnesium hydrato carbonate. It has been a common practice until recently among pharmacists to prepare peppermint and other aromatic waters by triturating the essential oil with light carbonate of magnesium, adding water and filtering. But owing to the slight solubility oE the magnesium salt in water it has been largely replaced by calcium phosphate, talc, and other insoluble substances. When aromatic waters prepared by the aid of magnesium carbonate were prescribed with the acid solution of strychnine hydrochloride of the 1885 Pharmacopœia no change took place, but in the case of the present official solution, which does not contain free acid, the strychnine gradually crystallises out. This change was noticed owing to an empty three-ounce dispensing bottle being sent to a pharmacist to be refilled with a mixture containing one fluid drachm of the official strychnine solution in three fluid ounces of peppermint water. The inside of the bottle was found to be coated with small crystals representing the greater part of the strychnine. It is obvious that an incompatibility of this kind presents two serious inconveniences. In the first place, the patient does not take the full amount of strychnine ordered by the prescriber and in the second place there is considerable danger of the patient taking the bulk of the alkaloid in the last dose. Mr. Hill’s valuable communication has probably given this unscientific method of preparing aromatic waters its death-blow, while it has afforded an interesting and important example of the unexpected results that may attend the modification, in however slight a degree, of official formulas. It emphasises, too, the necessity of a strict adherence to the Pharmacopoeia, which directs aromatic waters to be prepared by distillation and without the use of magnesia or other substances.

SMELLS IN THE HOUSE OF COMMONS. THE proceedings in the House of Commons on June 21st were interrupted by a Member suddenly asking whether the Government was aware of the presence of sewer gas in the House? "The same thing occurred yesterday. Can anything be done to purify the atmosphere of the House? It is simply poisonous." Mr. Harcourt subsequently reported that what had happened was that a barge filled with gas liquor had The same been taken down the river for disposal at sea. barge the day before had given rise to a similar complaint and he would endeavour to make arrangements with the gas THE ETIOLOGY OF GENERAL PARALYSIS. company for the adoption of some other hour for conveyance.

by the eminent French surgeon is increased in this instance by the fact that he is one of the most extreme advocates of the operative treatment of appendicitis, holding that it is the sole efficacious and rational method. "Remove the toxi-infectious appendicular focus before it can become fatal " is his rule. He related 12 cases of which the following are some examples. A man was admitted into the Hôtel Dieu who had undergone operation for " appendicitis." The surgeon sent with him the appendix which was sound. The patient was suffering from an attack of mucomembranous typhlo-colitis which followed the same course as other attacks which occurred before the operation. In a second case M. Dieulafoy saw in consultation a young man who had suffered for a long time from muco-membranous typhlocolitis. Finding a scar in the right iliac fossa he said, "You have been operated on for appendicitis." "Yes," replied the patient, " for appendicitis which I had not." In a third case a woman suffering from the same disease gave the same history. She continued to suffer just as before operation. On examination there was pain in the right iliac Eossa like that of appendicitis. In a fourth case M. Dieulafoy saw in consultation a young woman who had suffered for announcement

It is possible that the appellants will make application to quarter sessions for a re bearing of the appeal, in which event we should not be justified in making any comment on the aspects of the case. The proceedings are costing a considerable sum of money and it is unfortunate that they should have ended in this fiasco. We cannot help thinking that the trade would be well advised if they ceased to fight the matter out in court and if they would come to an agreement all round to make a clean breast of it and adopt an honest, straightforward description of their goods.
