■efforts that he lost daring the vojage home only one man who was hope- 

 lessly diseased, and on his return he received the thanks o£ the military 

 authorities. 



In 1811 he commenced practice in LoDdon, in Hunter Street, Bruns- 

 wick Square. He was acquainted with the French, Spanish, and Italian 

 languages ; and he had among his patients a large number of foreign 

 refugees who resided in that neighbourhood. He obtained the diploma of 

 the College of Surgeons in 1313. Although fully engaged in medical 

 practice, Iveil Aruott's mind was still much directed towards chemistry 

 and physics, and in this year he gave at the Burton Eooms a course of 

 lectures on Xatural Philosophy applied to Medicine. The novelty and 

 utility of this course rendered it highly attractive to medical men. At 

 a later date (1825), when residing in Bedford Square, he gave two 

 courses of lectures on the same subject, chiefly to members of the 

 medical profession. He declined, however, to continue these courses ; 

 and in the year 1827 he published the substance of them in his ' Ele- 

 ments of Physics.' 



In 1811 the University of Aberdeen conferred upon him the degree 

 of M.D. He practised for many years as a physician, and held the 

 appointments of physician to the Prench and Spanish Embassies. 

 As a physician Dr. Arnott placed more confidence in regimen than he 

 did in drugs. Pie made many useful mechanical suggestions for the 

 treatment of certain diseases, such as hernia, stricture, &c. It was from 

 1838 to 1855 that he was in the height of his professional career. He 

 then withdrew from practice, and devote^, his time almost exclusivelv to 

 scientific subjects, including also those of a sanitary nature. In this year 

 he published an account of his smokeless grate, a modification of the 

 open fire-grate, but possessing many of the advantages of the stove. 

 This invention included a complete combustion of smoke and a great 

 economy of fuel with a steadiness and endurance of the fire. It was in 

 reference to this invention that in 1851 the Eumford ]\Iedal of the Eoyal 

 Society was awarded to Dr. Arnott. 



In 1832 he first made known the use of the Hydrostatic or Yrater- 

 bed. which has proved of such important service in medical practice. 

 Devoting his attention to sanitary appliances, including the proper 

 methods of warming and ventdating dwelling-houses, hospitals, and infir- 

 maries, he introduced the stoves which are well known by his name. 

 In his essay on " Warming and Ventilation, published in 1838, he gave 

 a full description of his stove. Por this and other novel appliances in the 

 treatment of disease and the preservation of public health, the Jurors of 

 the Lmiversal Exposition of Paris, in 1855, awarded to him a Gold I\Iedal, 

 to hich the Emperor jN"apoleon III. added the Cross of the Legion of 

 Honour. 



On the foundation of the P'niversity of London, in 1836, Dr. Arnott 

 was appointed one of the original Members of the Senate. In 1837 he
