Of recent years a modification in Albania prepared at the request of the Albanian of the element has-been prepared known as activated Government, a request from the Turkish Government in which these properties are very highly for the appointment of an expert to help in organising developed as compared with the best bone black or an anti-malaria campaign in Turkey, and a note from other hitherto known variety of carbon.

The methods of Owing to the depreciated exchanges, this question of manufacture are complicated and require great the cheapest and most effective drugs to use against experience, one general process, for example, being malaria is of fundamental importance in the work of to carbonise under regulated and definite conditions the Health Organisation on this subject. carefully prepared carbonaceous mixtures, followed by an elaborate purification and extraction. In connexion with the manufacture it is right to mention THE PROGNOSTIC SIGNIFICANCE OF the firm of Sutcliffe, Speakman, and Co., Ltd., of SCARLATINAL NEPHRITIS. Leigh, Lancashire. An important technical application of activated OUR knowledge is still very incomplete as to the duration of the damage inflicted by an attack of carbon is the extraction and purification of gases, espescarlatina on kidneys which, through the acute stage cially the direct separation of motor spirit from the of the disease, have reacted with albuminuria.

These are some of the questions tion of obnoxious smells and vapours. The decolorwhich Dr. H.

In the the method being of considerable advantage for the 10-year period, 1911-1920, his hospital admitted purification of tallow, coconut oil, linseed oil, peanut 75 per cent. of all the cases of scarlatina notified in and corn oil, cotton-seed oil, and castor oil.

Among the 14,339 cases of scarlatina latter case, for example, fuller’s earth is at present admitted in this period, there were 612 complicated used, but the addition of activated carbon, about by hsemorrhagic nephritis. After subtraction of the 5 per cent. by weight, gives far superior results. For solutions the material is finding the most extensive cases which proved fatal in the acute stage of the disease, there remained 588 patients, 284 of whom application, especially for cane-sugar, glucose, were re-examined from one to ten years after discharge, brewing sugars (maltose and lactose), tartaric acid, the heart and blood pressure as well as the urine cream of tartar, citric acid, lactic acid, and organic being investigated. Dr. Hansborg made a point of compounds used as intermediates in dyestuff examining the morning urine in those cases in which manufacture, together also for the extraction of gold orthostatic albuminuria was suspected, and he found from excessively dilute solution 1 part per 10,000,000 that among the 284 ex-patients there were 23 who in the cyanide process.
