116 THE CANADIAN NATURALIST. [Dec. 



4. The name of each of the 13 metalloids terminates with a 

 different consonant ; arsenic and tellurium, classed by some 

 chemists among the metalloids, are by this arrangement included 

 among the metals. 



5. The number of atoms of any element is designated by the 

 vowel immediately preceding the terminal consonant. The 

 numerical power of the vowels advances with the order in which 

 they are placed in the alphabet, thus 1, 2, 6, 4 and 5 are repre- 

 sented by a, e, i, o and u, each having a short or stopped sound, 

 and the same vowels, each preceded by e, and having the long or 

 full sound, represent 6, 7, 8, 9 and 10. Other letters represent 

 higher numbers, so that any number to 1000 is readily denoted. 



6. The following metalloids are represented by their symbolic 

 letters : One atom of Fluorine is of, one atom of Bromine ab, 

 one of Nitrogen an, one of Carbon ac, one of Sulphur as, one 

 of Phosphorus, ap. For reasons which] need not here be 

 stated, an atom of Hydrogen is al, of Oxygen at, of Chlorine ad, 

 of Iodine av, etc. 



7. The manner of uniting these syllables may be thus illustrated : 

 The protoxide of iron is Ferramat ; the sesqui-oxide of iron, 

 Ferremit; the black or magnetic oxide, Ferrimot ; sulphate of 

 protoxide of iron, Ferrmasot ; sulphate of sesqui-oxide of iron, 

 Ferremisoit. 



The combinations containing carbon and hydrogen are so 

 numerous that it was found essential to use another letter, r, to 

 designate carbon — ar and ac each denote an atom of carbon. Two 

 atoms of hydrogen are designated by h, thus ach is equal to 

 C 2 H 2 in the old notation. This is the important increment in 

 several series of organic radicals. The first of the alcohol-forming 

 radicals is achal, methyl ; the second, echal, ethyl ; the third, 

 ichal, propyl ; the fourth, ochal, butyl ; the fifth, uchal, amyl, etc. 

 These radicals play the part of monatomic metals. 



The author gave specimens of the new names for several 

 thousand compounds; and showed their application in cases of 

 isomerism, where, for instance, ten bodies, having the same ultimate 

 components, are distinguished by ten different names. The 

 doctrine of substitutions was also very clearly set forth ; and 

 derivatives were so classified and simplified as to be readily 

 comprehended. 



The author then proceeded to show the manner in which 

 names were provided for salts containing water of crystallization,
