and on the spontaneous inflammability of phosphuretted hydrogen. It 

 would not, however, be appropriate in this place to do more than 

 enumerate the subjects of these less important studies ; and we have 

 therefore only aimed in this sketch to give a general view of the 

 character of the field which this eminent student of nature chiefly 

 cultivated, and to show how abundant was the harvest of truth which 

 we owe to his faithful toil. 



Graham was not a voluminous writer. His scientific papers were all 

 very brief, but comprehensive, and his " Elements of Chemistry " was 

 his only large work. This was an admirable exposition of chemical 

 physics, as well as of pure chemistry, and gave a more philosophical ac- 

 count of the theory of the galvanic battery than had previously appeared. 

 Our late Associate was fortunate in receiving during life a generous 

 recognition of the value of his labors. His membership was sought by 

 almost all the chief scientific societies of the world, and he enjoyed to a 

 high degree the confidence and esteem of his associates. Indeed, he 

 was singularly elevated above the petty jealousies and belittling quarrels, 

 which so often mar the beauty of a student's life, while the great love- 

 liness and kindliness of his nature closely endeared him to his friends. 

 He was never married, keeping house with a sister at No. 4 Gordon 

 Square, where he dispensed a liberal hospitality, which has been en- 

 joyed by many of .our scientific countrymen who have visited London 

 during the last twenty years. 



In concluding, we must not forget to mention that most genial trait 

 of Graham's character, his sympathy with young men, which gave him 

 great influence as a teacher in the College with which he was long 

 associated. There are many now prominent in the scientific world 

 who have found in his encouragement the strongest incentive to 

 perseverance, and in his approval and friendship the best reward of 

 success. 



Frederic Overbeck was born at Lubeck on the 2d of July, 1789, 

 and commenced his studies in art at a very early age. In 1806 he 

 entered the Academy of Fine Arts at Vienna. His natural tendencies, 

 fostered by the counsels of Eberhard Wachter, soon led him to the 

 exclusive study of the Pre-Raphaelite painters. This brought him 

 into such open opposition to the professors, whose principles were 

 those of the classical school of Mengs and David, that he was dis- 

 missed from the Academy, and in the year 1810 went to Rome, 

 where he found himself in a thoroughly congenial atmosphere. Six
