45. On certain accidents to which coal- 

 works are liable, particularly those of water 

 bursting into the pits from old works that are 

 near adjacent, as recently occurred at Heaton in 

 Northumberland ; the accidental explosions of 

 fire-damp, setting fire to the waste coals in the 

 works, as happened last summer at Brora in 

 Sutherland ; and the spontaneous firing of loose 

 small coals arid pyritic dirt, &c. Tilloch, Phil. 

 Mag. XLV.. 1815, pp. 436-452.

 tions. Tilloch, Phil. Mag. XLVIL, 1816, pp. 



86; Paris, Soc. Philom. Bull. 1816, p. 1 12.

 loch, Phil. Mag. XLVIH., 1816, pp. 427-431.

49. A supplementary table of Musical 



Intervals, for supplying the omissions in plate 

 5 of our XXVTIIth Volume ; making several 

 corrections therein, and supplying the new

 are expressed in the letter-press of our work, 

 for the convenience of printing. Tilloch, Phil. 

 Mag. XLIX., 1817, pp. 360-361.

 of simple equations. Tilloch, Phil. Mag. XLIX.. 

 1817, pp. 362-367. 



51. On Mr. LISTON'S, or the Enharmonic 



Scale of Musical Intervals, extended according 

 to his tuning process, from 59 to 612 notes in 

 the octave ; showing thus, a division of the 

 octave into 612 equal parts, or as nearly so 

 throughout as experiments in harmonics, or 

 the most refined musical performances seem to 

 require. Tilloch, Phil. Mag. XLIX., 1817, 

 pp. 442-448.

accurately discriminating fossil-shells as the 

 means of identifying particular beds of the 

 >trata in which they are inclosed; with a list 

 of 279 species or varieties of Shells, of which 

 the several stratigraphical and geographical 

 localities are mentioned, which seem to require 

 the particular and minute attention of the col- 

 lectors and examiners of fossil shells in their 

 natural deposits. Tilloch, Phil. Mag. LIU., 

 1819, pp. 112-132. 



54. Free remarks on the Geological Work 



of Mr. GREEXOUGH. Tilloch, PhiL Mag. LIV.,

55. A stratigraphical or Smithian arrange- 

 ment of the fossil shells, described by Martin 

 LISTER in his " Historia Animalium Angliae." 

 Tilloch, Phil. Mag. LIV., 1819, pp. 133-138.
