To the use of the above symbols there are a few exceptions. 
Some chemists, instead of K, Na, and Pt, use Po, So, and PI, 
for potassium, sodium, and platinum. These are improper 
deviations from the original plan, and should be avoided as 
innovations tending to introduce synonymous expressions, 
and to complicate what is otherwise simple. 
These symbols are intended to denote single equivalents of 
the elementary bodies; thus C expresses one equivalent of 
carbon; CI, one equivalent of chlorine; 0, one equivalent of 
oxygen, «&c, without the necessity of saying 1C, lCl, 10, &c; 
but when more than one equivalent is intended, then a figure 
indicating the number must be prefixed, as 2C, 3C1, 40, for 
two equivalents of carbon, three of chlorine, and four of oxy- 
gen. The manner in which several elements, having the 
same initial, are distinguished from each other, will be readily
