WATER has three distinct functions recognized in the notation, but not in 

 the common nomenclature, which are clearly defined in the new system. 



1. Water as a true chemical component : it is thus designated by elat, alalt 

 or lalt. The first of these names, when forming a part of another name, may 

 denote the typical structure and the rational formula of the compound : it 

 may indicate, likewise, that precisely the same number and kind of atoms, 

 by another arrangement, would form two independent and stable bodies ; for 

 instance, echelat denotes that alcohol is formed by the combination of the 

 radical echal with the water torso alat or alt, and is modeled after the dyad 

 type ; it also indicates the fact proved by the synthetic process of BERTHELOT, 

 that alcohol contains all and precisely the components forming olefiant gas and 

 water. The other name of water, alalt or lalt, shows more clearly how the 

 torso alt, torn from al, will unite with a monad radical or metal and form a 

 perfect body, like, for example, hydrate of potash, potamalt ; hydrate of lime; 

 calcamelt. 



2. Water as a mechanical component of certain crystals. Under the plastic 

 trowel of symmetry, it fills the interstices, so to speak, builds up and com- 

 pletes the structure. During this mysterious process of construction, the pair 

 of hydrogen atoms are supposed to still cling to oxygen ; and the molecule 

 having such close atomic ties is distinguished by the term allt. This is the 

 only case where the same consonants are found side by side : the relation in 

 which the word is used will prevent its being confounded with the tono alt. 

 By changing the vowel prefix, any number of molecules, either of water of 

 crystallization, or of constitutional water as GRAHAM styles it, may be denoted. 

 As a general rule, this name precedes the essential name of the compound ; 

 for example, 



Crystallized periodic acid, with 4 atoms of water, 



Crystallized oxalic acid with 2 aqua, 



Prismatic nitrate of copper with 3 aqua, 



Rhomboidal nitrate of copper with 6 aqua, 



Nitrate of lime with 4 aqua, 



Nitrate of strontia with 5 aqua, 



Nitrate of lithia with 5 aqua, 



Protonitrate of iron with 6 aqua, 



Hyposulphite of soda witb 5 aqua, 



Sulphate of soda with 10 aqua, 



Carbonate of soda with 10 aqua, 



Sulphate of alumina and potash with 24 aqua, . 



Sulphate of alumina and thallium with 24 aqua,
