KEYS. 



The keys are constructed in the usual way, and indented in the 

 same way. in addition the system of Capital letters in used to pre- 

 vent any conffusion (which often occurs in the old way). The letter 

 "A" represents the first section of each main group such as the Hom- 

 alobi. Each succeeding "A" represents a coorelative section of the 

 same group. The letter "B" stands for the first subsection, of "A", 

 and every other "B" stands in the same relation, and so on with every 

 letter used, each one is subsidiary to the letter which precedes it in 

 the alphabet. 5A6B3C2D represents the second division of the third 

 division of the sixth division of the fifth division of the main group.
