VISIT TO EUROPE: RESIDENCE IN LONDON. 153 



On his way to Edinburgh, he stopped for a short 

 time at Cambridge. 



Arriving at evening, I had drawn my boots off, and with 

 pen in hand was just beginning to write, by a comfortable 

 fire in my chamber in the hotel, when I received a call 

 from one of the Fellows, to whom I forwarded a letter of 

 introduction from London. He insisted upon my going 

 over to his apartments to sup with him, and the invitation 

 was so kindly pressed that I complied, and enjoyed a very 

 pleasant interview with a most agreeable and polished gen 

 tleman, the Rev. Mr. Cunningham. The next day, by the 

 introduction of another Fellow, Rev. Mr. Currie, I dined 

 with a large circle of University men, Heads of Colleges, 

 Professors, Fellows, &c., and thus I was made to feel at 

 home. 



Elementary Chemistry, in 1805, was taught in the Uni 

 versity by Prof. Wollaston. Prof. Farish was the founder 

 of a new course of chemistry and mechanics, applied to the 

 arts. I called on this gentleman, to whom I had letters of 

 introduction, and was received with great courtesy and 

 kindness. He took me to the laboratory and showed me 

 his extensive apparatus. Prof. Farish made it his leading 

 object to demonstrate the most important applications of 

 chemistry and mechanics to the arts of life, and particu 

 larly to the manufactures of Great Britain, many of the 

 establishments of which he had in person visited for the^ 

 sake of inspecting their processes. He had a complete set 

 of models and machines, and of apparatus for the purpose 

 of carrying his designs into effect. A small steam-engine 

 served to illustrate the nature of that instrument, and the 

 moving power thus obtained was then applied to work the 

 rest of the machinery. 



Lindley Murray, a man equally distinguished in a 



different line, that of English grammar and philosophy, 

 resided near York at the time of my visit here in Novem-
