tural adaptability, as monads, they are found among the components of many 

 bodies. Those well investigated may be estimated in round numbers thus : 

 Chlorides 750, iodides 320, fluorides 160, bromides 150; to which maybe 

 added another class of very similar structure, the cyanides 220 : total, 1630. 

 In this estimate, several hundred chlorhydrates, bromhydrates and iodhydrates 

 are not included. Their new names will be so readily understood, it is only 

 essential to present such examples as will explain the changes required by the 

 atomic notation and the typical classification.
