 'Rankine was one of the little group of thhikers to ^vholIl, after the wondrous Sadi Carnot, the world is indebted for 



the pure science of modern thermodynamics. But his services to applied science were relatively e^ en greater. By his 



adniira1)le teaching, his excellent textbooks, and his original memoirs, he has done more than any other man of recent 



times for the advancement of British Scientific Engineering \—Prof. Tait.

' His most extensive work in astronomy was the eclii)se volume of the R. A. y. (Memoirs, vol. XLi;, in which are 

 systematised and discussed the observations of all solar eclipses down to 1878. It was originally commenced in con- 

 junction with Sir George Airy, but soon devolved on Ilanyard alone'. — D. N. 11. 



' In his splendid volume on eclipses, with which the systematic study of coronal structure may be said to have l>eg«n, 

 Mr. Ranyard first generalised the synclinal peculiarity by a comparison of records. He further pointed out the curved

Of particular interest as written when the Absolute Block System had coine largely into use, but was not yet compulsory, 

 and by no means universally accepted. It gives an excellent account of the gradual development of railway signallinj; 

 and interlocking, and the details of the signalless railways of the 'Thirties, when a policeman with atoi)-hat, a flag, and a 

 stable lantern controlled what were already busy junctions, are very curious. The Discussion on the papei- is of nearly 

 equal value.

Raspe was one of the first to adopt the view that basalt was of volcanic origin. The work (which is unknown to 

 Poggendorff), is also of interest for the personality of its author, a German professor at Cassel, Avho fled to England in 

 1775 to avoid punishment for theft. He was elected a Fellow of the Royal Society, but struck off the rolls on his 

 antecedents becoming known. He was the author of the original ' Baron ilunchausen *, and a swindler of a most 

 interesting type, on whom the character of Do-^tstersmvcl, and the incidents connected with him, are based in Sir Walter 

 Scott's Antiqiiary. Sec also Borx (Xus. i)341-'2), ante.
