 1815, pp. 26-28.

made in the summer of 1814 in the south of 

 Yorkshire and in North Wales, and of some 

 inferences therefrom as to the structure of 

 England and Wales. Tilloch. Phil. Mag. XLV..

. 44. Observations on the priority of Mr. 



SMITH'S investigations of the strata of England.

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 and pyritie dirt, &c. Tilloch, Phil. 

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



46. On a curious property of vulgar frac- 

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

 385-386 ; Paris, Soc, Philom. Bull. 1816, p. 1 12. 



47. Remarks and suggestions for further 



improving and applying to use the Government 

 Trigonometrical Survey of Great Britain. Til- 

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



48. Remarks and suggestions for improv- 

 ing the British coin, and the keeping of money 

 accounts, preparatory to the entire introduction 

 of decimal money. Tilloch, Phil. Mag. XLIX.. 

 1817, pp. 16-23. 



49. A supplementary table of Musical 



Intervals, for supplying the omissions in plate 

 5 of our XXVlIIth Volume ; making several 

 corrections therein, and supplying the new 

 symbols, by which certain of these intervals 

 are expressed in the letter-press of our work, 

 for the convenience of printing. Tilloch, Phil. 

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



50. On the nomenclature of Musical In- 

 tervals, and the advantages of a set of symbols 

 or characters, by which the mutual relations of 

 the principal ones can be expressed, in the form 

 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.

 stated. Tilloch, Phil. Mag. LI., 1818, pp. 173-

53. On the importance of knowing and 

 accurately discriminating fossil-shells as the 

 means of identifying particular beds of the 

 strata 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. LIIL, 

 1819. pp. 112-132. 



54. Free remarks on the Geological Work 



of Mr. GREENOUGH. 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. 



56. On different modes of expressing the 



magnitudes and relations of musical intervals ; 

 with some remarks in commendation of Prof. 

 FISHER'S proportionally tempered Douzeave.

Geological Map. Tilloch, Phil. Mag. LV.,

58. On the specific gravities of the gases, 

 and the different musical sounds which they 

 occasion in the same organ-pipe. Tilloch, Phil. 

 Mag. LVI., 1820, pp. 412-415.

 motion by marine steam engines. Civil Eng.
