154 THE LIFE OF JAMES D. FORBES. [CHAP. 



then together travelled to London, and thence to the 

 Continent. In June and the early part of July they 

 were travelling companions among the Pyrenees. After 

 traversing these, they parted at Grenoble John Mackin- 

 tosh to return to Scotland, Forbes to meet Agassiz on 

 the Aar glacier and to ascend the Jungfrau. For the 

 next ten years they two kept up by letter an interchange 

 of true and tender affection, to be closed only by the last 

 letters which shall be given at the proper time. 



Returned from this, to him, eventful Alpine summer, 

 Forbes employed what remained of the autumn before 

 his winter work began in throwing his observations and 

 reflections on what he had seen, into the shape of an 

 article on Glaciers for the Edinburgh Review. This 

 article appeared in April 1842, and was well received, 

 and almost at once translated into French. He was 

 at the same time invited by Murray and Lockhart to 

 write for the Quarterly on the same or on kindred sub- 

 jects ; but this he appears not to have done, though, 

 in his general views of things unscientific, his sym- 

 pathies went more with the Quarterly than with the 

 Edinburgh. 



In May 1841 he and his surviving sister left their old 

 home at Dean House, in which they had lived since 

 1835, as it was to be pulled down to make way for 

 some large changes in that neighbourhood. They took 

 up their abode for a time in a house in Ainslie Place, in 

 which, however, they passed only two winters. 



The winter session of 1841-42 was, if possible, a 

 more than usually busy one. Besides his class work, his 

 spare hours were given to the preparation of a paper on 

 astronomical refraction, uhich was to be read before 

 the Royal Society of London. He also prepared and 

 delivered in his class-room some lectures on Glaciers, 

 which, being open to the public, were numerously at- 

 tended. He was, in addition to all this, preparing for a 

 new and still more vigorous campaign among the Alps 

 next summer. 



As soon as the close of the session 1841-42 allowed,
