400 by the Regulin Syndicate, Limited (15, Cullum-street, London, E. C.). Messrs. Parke, Davis, and Co. (50, Beak-street, Regentstreet, London, W.) offered for inspection a great number of preparations of pharmacological importance. They draw attention to the development of physiological standardisation initiated in their laboratories 20 years ago, citing examples of the importance of its application in digitalis and strophanthus. Their exhibits included a selection of serums and vaccines, sterilised solutions for hypodermic use, the phylacogens, glandular extracts (e.g., adrenalin), and a number of other scientifically prepared substances of ascertained pharmacological potency. Messrs. Fairchild Brothers and Foster (64-65, Holborn Viaduct, London, E. C.) exhibited chiefly preparations whose value depends upon enzyme activity. Such were, for example, enzymol, a solution of proteolytic enzyme prepared for external use for hydrolysing sloughs, &c. ; zymine, extract of pancreas ; holadin, of powerful tryptic activity, sometimes combined with bile salts. Lastly, they exhibited a valuable and permanent preparation of lecithin in glycerine, glycerole, which is available for use in impairment of general nutrition.

New Inventions. TONSILLECTOMY AND A NEW GUILLOTINE. WITHOUT wishing to enter in any way into the rival merits of tonsillotomy and tonsillectomy it must nevertheless be admitted that there are a number of cases which call for the latter procedure. To accomplish the enucleation or removal of the tonsil complete in its capsule there are two methods which are generally accepted, firstly, the dissection method, with its endless modifications, and secondly, the so-called Sluder or blunt guillotine method. A large experience of the latter method almost from the day of its introduction has convinced me that about 95 per cent. of all cases can be successfully dealt with by it, but it must be admitted that in a certain number of cases the operation to be successful must be accompanied by the exhibition of rather an undesirable amount of force. The reason for this is that after the blunt blade of the guillotine has been made
