tions of the atmospheric forces. Humboldt records the circumstance 

 that, when, like Balboa on the summit of the Sierra de Quarequa in 

 Darien, he and his companions from the top of the Andes caught their 

 first view of the Pacific Ocean, so great was their joy, they forgot to 

 open their instruments, and every thought was hushed that they might 

 drink in the scene expanding before them. How much more will the 

 meteorologist of the near future, whose mental eye catches a clear 

 glimpse of the Aerial Ocean, mirrored in the modern chart, be lost in 

 admiration, yet constrained to admit with the ancient seer, "Lo ! these 

 are but parts of His ways ; how little a portion is heard of Him, but 

 the thunder of His power who can understand ? "

By ALEXANDER BAIN, LL. D., 



PROFESSOR OF LOGIC IN THE TNIVERSITT OF ABERDEEN. 



WHAT I have to say on the ten years from 1848 to 1858 may be 

 conveniently introduced by a reference to the " Autobiogra- 

 phy," p. 237. Mill states that, for a considerable time after the publica- 

 tion of the " Political Economy," he published no work of magnitude. 

 He still occasionally wrote in periodicals, and his correspondence with 

 unknown persons on questions of public interest swelled to a consid-

 and social subjects, and kept a watch on the progress of public 

 events. 



The year 1850 was chiefly noted for the first important revision of 

 the " Logic," namely, for the third edition. He had to answer many 

 attacks upon it, including a pamphlet by Whewell. As I was absent 

 from London while this was going on, I had a good many letters from 

 him, chiefly on Whewell's criticism, of the weakness of which he had 

 a very decided opinion. I suggested some alterations and additional 

 examples, but I scarcely remember what they were. The edition was 

 printed in November ; and no revision of anything like the same extent 

 was undertaken till the eighth edition came out in 1872, 



The " Political Economy " was subject to more frequent revisions, 

 and occupied a good deal of his attention at one time or other, but I 

 did not keep pace with him on that subject. 



In the spring of 1851 took place his marriage to Mrs. Taylor, In 

 the autumn of that year I took up my abode in London again, and re- 

 mained there or in the neighborhood till 18G0. I continued to see him
