HISTORICAL 7<br />
formula (supposedly) C14H16 had been isolated, <strong>and</strong><br />
that, by determining the vapor density, they had proved<br />
it to be just half this molecular weight, or C7H8. On<br />
the other h<strong>and</strong>, there is no reason why—if they did<br />
know of the previous discovery of this same substance<br />
—they should give it a new name. The dates on<br />
which the above-mentioned men published their article<br />
seems to point to Pelletier <strong>and</strong> Walters as the discoverers—their<br />
work was completed about 1838,<br />
while Deville's work was published somewhere about<br />
1841. Of course, there is the possibility that Deville<br />
completed his work some years before his results were<br />
published.<br />
In 1843, Berzelius technically accorded the discovery<br />
of toluene to Deville by suggesting the name " toluol "<br />
or " toluene " for the compound, (3) the name being<br />
derived from " oil of tolu."<br />
Some of the scientists of that period (probably<br />
friends of Pelletier <strong>and</strong> Walters), did not approve of<br />
Berzelius 7 choice of name for this substance, <strong>and</strong><br />
two of these, Muspratt <strong>and</strong> Hoffman, in a research<br />
paper dated 1845, take occasion to remark: (4) " Berzelius<br />
has proposed for this compound the name l toluol<br />
' or ' toluene/ names which are not very well<br />
chosen, but which we shall retain in the following discussion."<br />
The " retinaptha " of Pelletier <strong>and</strong> Walters <strong>and</strong> the<br />
tc benzoen " of Deville were proved to be the same substance<br />
by the preparation of the nitro-derivatives, <strong>and</strong><br />
by comparing the constants of those, <strong>and</strong> possibly the<br />
acid nitro-derivatives <strong>and</strong> corresponding toluidins.<br />
Glenard <strong>and</strong> Boudalt, at about the same time, probably<br />
later than both Deville's <strong>and</strong> Pelletier <strong>and</strong> Wai-
