zvhich 'becomes a violet coloured Gas by Heat, 
The name ione has been proposed in France for this new 
substance from its colour in the gaseous state, from lov, viola ; 
and its combination with hydrogen has been named hydroionic 
acid. The name ione^ in English, would lead to confusion, for 
its compounds would be called io?iic and Ionian, By term- 
ing it iodine, from .violaceous, this confusion will be 
avoided, and the name will be more analogous to chlorine and 
fluorine. 
The acid it forms with hydrogen may, however, be with 
propriety named in our language hydroionic acid. I venture to 
propose for the acid it forms with chlorine, the name of chlo- 
rionic acid, and for that it forms with tin stannionic acid. With 
respect to the other compounds, they may be called as a class 
iodes, with the name of the base as iode of rnercury, and with 
proto, deuto, &c. to signify the proportions ; or if a termination 
to the base should be preferred, as I have proposed f^^r the 
combinations of chlorine, the terminations may be in m, with 
the vowels in their usual order to signify proportions. Thus, 
phosphoroma \\’ould signify the combination of one proportion 
of iodine with phosphorus, and phosphorome would signify 
two proportions of iodine to .one of phosphorus. 
If this last plan, which involves no theoretical views, 
should be adopted, it may be extended with different conso- 
nants to the combinations of fluorine,, the vowel may be 
made to signify the .proportion,. and the consonant the nature 
of the compound. The vowel of termination, to the Latin 
name of the base, I have already proposed, on another occa- 
sion, for the compounds of oxygen. Thus argenta may be 
made to signify the protoxide of silver, and ferre the deut- 
oxide of iron, n is the consonant which I have suggested to 
N 2
