These maps, while exhibiting the geognostic work done in Bavaria, also 

 illustrate the mode in which the maps published on the scale of 1 : 100,000 

 have been produced. The land tax maps scale 1:5,000 have been used for 

 this purpose, and the observations made were entered on the spot (sheets 13- 

 15), and afterwards geognostically coloured. These observations have been 

 then transferred to maps of a different scale 1:25,000 (Sheet No. 16), then to 

 the military atlas 1:50,000 (No. 18), and lastly to the scale of those published 

 1:100,000 (1-11). Each original sheet maybe obtained for the actual cost 

 of production.
