55 Such is the melancholy history of this sad event. Mr. Toynbee was engaged in the fullest and most active pursuit of various scientific researches. He had organised the system of local natural history museums, which has spread throughout the kingdom. An accomplished microscopist and zoologist, he was elected president of the Quekett Club just before his premature death. His attention had long been directed to the various means of introducing vapours and gases into the middle ear by means of

... e Eustachian tube ; and two years since he caused a piece of mechanism to be devised by Messrs. Bell and Co. for the injection of chloroform vapour into the Eustachian tube through the nostrils ; this, however, had not answered, and in these last and fatal experiments he was probably trying the effect of that well-known natural effort, by which air can be driven in puffs into the Eustachian tube by closing the nostrils and mouth, and making a strong expiratory effort. A large part of the air thus impregnated probably passed the larynx and was.inhaled, thus producing a stupefying and ultimately a fatal effect. JOHN CROWN AGNIS, M.B., F.R.C.S., -ASSISTANT-SURGEON ROYAL HORSE GUARDS. MR. JOHN CROWN A&XIS was the representative of an ancient Cambridgeshire family. Dying unmarried, he was the last of his name and race. As a lad he gave promise of great ability. When sixteen years of age he entered at University College, London, as a student on the arts side, and soon distinguished himself by carrying off the senior Greek prize; being a mere boy in comparison with his competitors. He subsequently commenced his medical education at the same school, and, throughout a successful student career, developed in a high degree qualities of mind and heart which led his com-I peers to anticipate for him a bright future, and drew to him very many friends, whose loving fellowship continued to the end of his life. He became house-surgeon of the hospital, graduated as M.B. at the London University, and subsequently passed the fellowship examination of the College of Surgeons. Those who knew his great abilities were somewhat disappointed that he elected to enter life as an army surgeon. He was gazetted to the 3rd Light Dragoons, and afterwards became assistantsurgeon to the Horse Guards Blue. He held this post until his death on June 28th, in the thirty-eighth year of his age. A severe chill was followed by rheumatic meningeal inflammation, which terminated in serous effusion. This last illness was brief, but his general health had been previously impaired by a severe accident whilst hunting. He was a bold and skilful operator, notably endowed with that special surgical acumen which is logic in action. Some while before his untimely death he had taken into consideration the cogent solicitations of many friends desirous that his great abilities should be more widely appreciated, and had directed his attention to the subject of deformities, and energetically followed out a series of special researches into their general surgical pathology. When the Jacksonian prize for an essay on Clubfoot was awarded to Mr. Adams in 1864, the treatise of Mr. Agnis was considered so meritorious that an extra honorarium was adjudged in recognition of its special merits. The paper was accompanied by numerous illustrations drawn by the author; for Mr. Agnis, in addition to many other accomplishments, was a skilful artist. He was an enthusiastic entomologist, and versed in almost every branch of natural science. His death is deeply felt by a large circle of friends, and of these were all who knew him, MEDICAL VACANCIES.
