170 Mr Galbraith on Logarithmic Tables. 



not recollect what the erroneous figures were, and can find no trace 

 of them in wi'ithig. 



Callet, I No. 1024G7 log. 01058492 for 01053402. 



miS'v^ga!°°1 No. 106888 log. 02882995 for 02882S95. 



Hiilsse's Vega, at log. sin. 12° 10', Diff. to l"=97-50 for 97-60. 



In the first four, Callet seems to have committed the original 

 errors, from which the others appear to have been copied without suf- 

 ficient examination, though great pretensions are made by all to ex- 

 treme care. 



Bngay, Tan. 15 22 log. 9-9390485 for 9-4390485. 

 Sin. 34 40 log. 7-9546604 for 9-7549604. 

 Cot. 34 51 9 log. 10-157 (1550). 

 Cot. 34 51 10 log. 10-157 (1505). 



The fio-ures within the parentheses in the last two lines, have been, 

 in my copy, corrected by the pen ; and I do not now know what the 

 original figures were. 



Shortredc, Cot. 11 29 6 log. 10-9621845 for 10-6921845. 



Cos. 13 25 2Q 27 28 29 log. 10-987, &c., at top, for 9-987, &c. 



Cot. 19 6 7 8 9 log. 9-460, &c., for 10.460, &c. 



The above specimen, which might bo extended, shews that there 

 are as yet no tables extant possessing sufficient accuracy for our pub- 

 lic institutions and offices, whatever the professions of authoi's and 

 editors may be. 



You would oblige me by giving these a place in your Journal, so 

 that they may become more generally known. 



I am, dear Sir, your obedient servant, 



William Galbii.\ith. 

 To Professor Jameson.
