 ftance fplitting on deficcation, great intervals mufi have ex-

From all this it muft appear that philofophers have not 

 yet difcovered the procefs adopted by nature in the eonftruc- 

 tton of this beautiful and (hipendous work; but, though we. 

 cannot penetrate the fecret of her operations, it is with plea- 

 fure we admire her magnificence, efpecially when joined to 

 the mod confummate neatnefs ; and where are both io abun- 

 dantly difplayed as at the Giants' Caufevvay and its vicinilv ? 

 The toils of a journev are amply repaid by the contemplation 

 of fuch wonderful objects; and to thofe who are too diilant 

 for fuch an expedition, Mr. Robinfon's fine picture, finifbed 

 on the tpot, and now at Belfaft, will give a better idea of the 

 Giants' Caufevvay, and its towering promontories, than any 

 thing of the kind yet attempted. W. R.

JT remains for me to fpeak of a fubftance mentioned in the 

 Li thoph lacium Bominnum^ part i. p. 125, defcribed thus: — 

 " Ferrum retractorium, granuHs nitentibus, matrice viref- 

 centi immixtis, [Ferruvi virens Linn.,) cujus fragmenta, ab 

 unius ad vigenti ufi|iie librarum pondus, cortice nigro fcori- 

 aceo circumdata, ad plann, prope Tabor, circuit Bechinenfis 

 Bohemias, patfim reperitmtur. ' 



The iron thus defcribed is moreover made remarkable by 

 a note ", which obferves, that credulous people afiert it to 

 have fallen from heaven, during a thunder ftorm, on the 

 3d of July 1753. 



The collection of baron Born, it is well known, has a 

 place in the cabinet of the right horn Charles Greville, who, 

 from the effect produced by comparing the hiftories and (true- 

 ture of the Italian and Yorkfliire (tones with the defenption 

 of this iron, was induced to feareh the collection of Born, 

 where he discovered -the very iubltance after led to have fallen
