The hydrate of glyceryl, [C,H B -H S ]0, = echarlilt, is a triad alcohol. If il, 

 the second term, is replaced by three atoms of the monad anet = ineat, the 

 interesting explosive compound Nitroglycerine is formed, the three terms of 

 the type being [echarl-ineat]it = echarlineot. On the other hand, if il in 

 echarlilt be replaced by three atoms of the monad-acid radical C0C 17 H 35 , 



artaxeechal, the compound known as Tristearin is formed, containing 



C 57 H 110 6 = uxuchereat. In like manner, only two or one atom of hydrogen 

 may be replaced by two or one atom of the acid-radical. 



Artificial fats have been formed by the action of acids on glycerin, echarlilt ; 

 and the following from among the glycerides are presented, with their new 

 empirical names : 



Monacetin, C 5 Hi 04, uchot. 

 Monobutyrin, C 7 Hi 4 4 , eechot. 

 Monovalerin, C 8 Hi 6 2 , eichot. 



Monolein, C 2 iH 40 04, axeucharot. 



Monopalmitin, Ci 9 H 38 04, axeechot. 

 Monostearin, C 2 iH 42 2 , exachot. 



. That modification of sugar known as glucose or starch sugar, C 6 H 12 6 , has 

 lately been regarded by some chemists as a hexatomic or hexad alcohol. Ac- 

 cording to this view, its new name is earhalt. There are about thirty varieties 

 of sugars and gums of nearly the same composition, to which new names should 

 not be given until there is a general agreement among chemists as to their 

 composition and constitution. 



Artificial alkaloids, or compound ammonias of WURTZ and HOFMANX, formed 

 on the triad or ammonia type [al-al-al]an, in which an atom of hydrogen is 

 replaced by a radical, are thus illustrated :
