and a foetid otorrhcea was observed together with deafness in the left ear. He replaced one word for another, as in the use of adjectives," in speaking (paraphasia), but could read aloud without mistakes, understood written and spoken words, and wrote correctly from dictation. When shown an object, and asked to name it, he found it impossible, although he showed clearly that he knew the object and its uses. A large number of objects were tried with the same results. ’’Whenever he miscalled the object he knew his mistake at once, and after several attempts to give the correct name gave up in despair." When his name was mentioned he recognised it at once, but a few moments afterwards he failed when asked his name. He appeared to understand all written and spoken words. The urine was normal. The

Perhaps his most epoch-making discovery was his demonstration of the true nature of glycerine as an alcoholic body capable of interacting with three molecules of such acids as acetic and palmitic, although his contributions to thermal chemistry were models of ingenuity, resource, and orginal conception. Later he attacked the question of synthesis and until the publication of his Chimie Organique fondee sur la Synthese" no systematic research had been attempted in the direction of building up compounds of carbon comparable with natural organic compounds by the union of the elements of which they are composed. We must remember, however, Wohler’s synthesis of urea in 1828 and Kolbe’s synthesis of acetic acid in 1845. But the methods subsequently employed by M. Berthelot were more simple and direct. He started, for example, with the elements themselves. He took carbon and hydrogen which produced acetylene ; adding more hydrogen he got ethylene, and from this he obtained alcohol and a series of organic salts. Again, he set himself the task of proving that compounds identical in every respect with the products of animal and vegetable life may be formed from dead mineral matter. Thus in a series of experiments he employed the carbon obtained in the form of carbon dioxide from barium carbonate. It was then made to pass successively through the forms of carbonic oxide, formic acid, barium formate, ethylene, ethylene bromide, ethylene again, and finally into ethyl-sulphuric acid and its crystalli,,ed barium salt, from which the ultimate object of

THE ROYAL DENTAL HOSPITAL OF LONDON. IT is to be hoped that the excellent work which is carriecif from year to year by the (now Royal) Dental Hospital* of London will meet with that substantial encouragement which it deserves. According to the statement madeH. Woodruff who presided on the occasion Mr. W. by of the annual dinner of the staff and present and past stu-dents of the hospital which was held at the Hotel Metropolethan 69,000 operations had been on Nov. 23rd no less conducted within the walls of the hospital during the. past 12 months and the work in the new hospital continued to increase at an enormous rate. The institution, is undoubtedly doing yeoman service in relieving thepoor and necessitous, for, as Dr. J. W. Washbourn pointed. out in proposing the toast of ’’The Hospital and School,"’ during the past year over 40,000 teeth had been extracted, upwards of 16,000 had been filled, and 350a people had been provided with artificial teeth. Dr. Washbourn referred also to the great progress which had been made in dental surgery since the hospital was foundeda progress to which the students of that hospital had in’ no small measure contributed. It was satisfactory to know that at last they had gained entrance into a building which was better fitted for the philanthropic and educational needs. of the institution. Since occupying the present new and commodious building the school committee had recorded on
