passed through many editions, and has experienced every variety of 

 reception — from hearty welcome and approval in some quarters to the 

 extremes of fierce denunciation, or of lofty scorn, in others. What- 

 ever its merits or demerits it has undoubtedly been successful in one 

 of its main objects, viz., in showing how baseless is the common 

 statement that " Science is incompatible with Religion." It calls 

 attention to the simple fact, ignored by too many professed instructors 

 of the public, that human science has its limits ; and that there are 

 realities with which it is altogether incompetent to deal. 



Personally, Stewart was one of the most loveable of men, modest 

 and unassuming, but full of the most weird and grotesque ideas. 

 His conversation could not fail to set one a-thinking, and in that 

 respect he was singularly like Clerk-Maxwell. In 1870 he met with 

 a frightful railway accident, from the effects of which he never fully 

 recovered. He passed in a few months from the vigorous activity of 

 the prime of life to grey-headed old age. But his characteristic 

 patience was unruffled and his intellect unimpaired. 



He became a Fellow of the Royal Society in 1862, and in 1868 he 

 received the Rumford Medal. 



His life was an active and highly useful one ; and his work, 

 whether it took the form of original investigation, of accurate and 

 laborious observation, or of practical teaching, was always heartily 

 and conscientiously carried out. When a statement such as this can 

 be truthfully made, it needs no amplification.

Dr. Owen Rees was born at Smyrna in November, 1813. His 

 father was a Levantine merchant, and married an Italian lady, by 

 whom he had a large family. Owing to his father's failure in business, 

 he was obliged to be educated at a private school, and for the same 

 reason many of his family in after years were compelled to reside 

 with him. This is probably the explanation of his remaining un- 

 married. He, however, found a good patron in his uncle, who was 

 a partner in the publishing firm of Longman and Co. In 1829 Owen 

 Rees was apprenticed to Mr. Richard Stocker, the apothecary at 

 Guy's Hospital, and he very soon showed his inclination towards 

 scientific pursuits, and especially to chemistry. He attracted the 

 attention of Dr. Bright, who requested his assistance in the analysis 

 of the secretions in diseases of the kidney, and in this way a lifelong 

 friendship sprang up between them. He made quantitative analyses 

 of the albumen and urea in the urine, and proved the presence of the 

 latter in the blood. His papers on this subject are to be found in 

 the ' Medical Gazette ' for the year 18S3. 



In the year 1837 he took his degree at Glasgow, and shortly after- 

 wards published a small work entitled ' Analysis of the Blood and
