Each of these classes was then divided into ten more subdi- 
visions which include all the intellectual works belonging to 
that class, and as we are only concerning ourselves with the class 
dealing with apiculture, namely class 0. 6, we find it coming 
within the figures 0. 60 to 0. 69 : 
0.6 Uselul arts — Applied science — Technology. 
0.60 Generalities. 
0.61 Medicine. 
0.62 Engineering. 
0.63 Agriculture. 
0.64 Domestic economy. 
0.6.5 Commerce — Transport. 
0,66 Chemical industries. 
0.67 Manufactures. 
0.68 Mecanichal industries and trades. 
0.69 Buildings. 
Each of these subdivisions was divided ngain into 10 further 
subdivisions and so on, and thus an encyclopedic classification, 
of which each special science forming part of the whole human 
knowledge capable of jjeing represented by a specified fraction, 
was obtained and subdivided into smaller fractions similarly 
specified, or to be specified, all being united to each other in 
regular order. 
Dividing then each group into 10 other groups, or subdivi- 
sions, which include all the works belonging to that division, 
and considering only in the tables that with which we are concerned, 
we see that agriculture 0. 63 was also in its turn subdivided 
into 10 other divisions, from 0.630 to 0.639 embracing all subjects 
on agriculture. So we find the branch apiculture numbered 0.638, 
including apiculture and silk-worm culture. 
All this knowledge, represented by the number 638 (^ffpici*/- 
ture-silk-worm culture) was again subdivided; to apiculture and 
bees being assigned the first place, namely 0.6381.
