TENERIFFE, 



AN 



ASTEONOMER'S EXPERIMENT; 



OB, 



Specialities of a Residence above 

 the Clouds. 



By C. PIAZZI SMYTH, F.R.S.S.L. & E., 

 F.R.A.S. 



CORBESPONDINO MEMBER OF THK ACADEMIES OF 

 SCIENCE IN MUNICH AND PAI.RRMO ; TROPESSOR 

 OF PRACTICAL ASTRONOMY IN THE UNIVERfilTY 

 OF EDINBURGH, AND HER MAJESTy's ASTRO- 

 NOMER FOB SCOTliAND. 



The object proposed in this Experiment ■was to 

 ascertain liow far astronomical observation can 

 l)e improved, by eliminating the lower third 

 part of the atmosphere. For the accomplish- 

 ment of this purpose, a large equatorial teles- 

 cope and other apparatus were conveyed in 

 Mr. Stephenson's yacht Titania to TcnerifFe, 

 in June and July, 1856. There— with the ap- 

 proval of the Spanish authorities, the instru- 

 ments were carried up the volcanic flanks of 

 the mountain, to vertical heights of 8900 and 

 10,700 feet, and were observed witli during two 

 months. 



During this period many interesting photo- 

 stcreograplis were taken by Professor Smyth, 

 at different points of the ascent, and they have 

 been printed with great success, under the 

 superintendence of James Glaisher, Esq., 

 F.U.S., for the illustration of the book. Cor- 

 rectness is thus ensured : and if the reader 

 ■wishes to enjoy the effects either of solidity or 

 of distance, effects which are the cynosures of 

 all the great painters, he has only to combine 

 the two photographs stcreoscopicallij,a,-aA those 

 bewitching qualities are produced.

 Second Edition. Post 8vd. Price 5s. cloth. 



"An excellent manual, containing o largo 

 amount of information on a subject little 

 known, and still less understood. We recom- 

 mend the volume to those who wish to know 

 wliat were the religious institutions and ad- 

 vantages of our remote ancestors." — CTericaJ 

 Journal, August 22, 1855. 



" The study of our early ecclesiastical history 

 has by some been considered one of great la- 

 bour ; but a little work, entitled ' Chronicles of 

 the Ancient British Church,' has so collected 

 the material from the many and variofls 

 sources, and has so judiciously classified and 

 condersed the records, that there is no longer 

 this plea. We recommend the work not only 

 to every student, but to every churchman who 

 feels an interest in the early history of his 

 chtircli." — JLiterary Churchman, June 16, 1855.
