answering to any given logarithm. It U as followa : Look for 

 the first two figuriw of the mantissa of the given logarithm iu 

 the first column of tho Table tu., -. mid in the same 



horizontal line with these two figures, in one of tho ten adjoin- 

 ing columns on tho right, umler tlio tltinlji-jure of tho mantissa 



top, you will find tho anti logarithm answering to tho 

 fii-at t !(,<: fi'/ures of tho mantissa. Next, in tho same horizontal 

 line with this number, in one of tho nine other columns, headed 

 Fourth t'i'jtire, and under tho fourth figure of tho mantissa at 

 the top, you will find a number which is to bo added to tho 

 iintiliigarithtu already found, in order to mako it tho complete 

 antilogarithm required. Now, according to the nature of tho 

 index of tho given logarithm, by tho rules laid down in our pro- 

 ceding lessons, point this antilogarithm that is, mark it either 

 as integer or decimal or mixed number, as tho case may bo 



u will have tho number required. 



nple. Let it bo required to find tho number correspond- 

 ing to the logarithm 0*1635. Here, looking for '16 in tho first 

 column of tho table, you find in tho same horizontal lin^ 'n one 

 of the ten adjoining columns on tho right, under 3 (tho third 

 figure of the mantissa) at the top, tho antilogarithm 1455 ; and 

 in the same horizontal line with this antilogarithm, in one of 

 the next nine adjoining columns, under 5 (tho fourth figure of 

 the mantissa) at tho top, the number 2, which is to bo added t > 

 1455; this being done, you have 1457 for tho complete anti- 

 logarithm required. Now, as the index of tho given logarithm 

 is 0, this indicates that the number must contain only one in- 

 teger figure ; and the antilogarithm 1457 being pointed accord- 

 ing to this index, you havo 1'457 for the number required. 



Had tho given logarithms been MG35, 2'1635, and 5-1635, 

 the corresponding numbers would have been 14'57 145'7, 

 and 145709.
