The term _attraction_, having been recommended by Newton as
a fit word to designate the force which produces chemical
combination, continued in great favour in England, where the
Newtonian philosophy was looked upon as applicable to every
branch of science. In France, on the contrary, where
Descartes still reigned triumphant, 'attraction,' the
watch-word of the enemy, was a sound never uttered but with
dislike and suspicion. In 1718 (in the notice of Geoffroy's
Table,) the Secretary of the Academy, after pointing out
some of the peculiar circumstances of chemical {18}
combinations, says, 'Sympathies and attractions would suit
well here, if there were such things,' 'Les sympathies, les
attractions conviendroient bien ici, si elles étaient
quelque chose.' And at a later period, in 1731, having to
write the _éloge_ of Geoffroy after his death, he says, 'He
gave, in 1718, a singular system, and a Table of
_Affinities_, or Relations of the different substances in
chemistry. These affinities gave an easiness to some
persons, who feared that they were _attractions in
disguise_, and all the more dangerous in consequence of the
seductive forms which clever people have contrived to give
them. It was found in the sequel that this scruple might be
got over.'
This is the earliest published instance, so far as I am
aware, in which the word 'Affinity' is distinctly used for
the cause of chemical composition; and taking into account
the circumstances, the word appears to have been adopted in
France in order to avoid the word _attraction_, which had
the taint of Newtonianism. Accordingly we find the word
_affinité_ employed in the works of French chemists from
this time. Thus, in the _Transactions of the French Academy_
for 1746, in a paper of Macquer's upon Arsenic, he
says[15\6], 'On peut facilement rendre raison de ces
phenomènes par le moyen des affinités que les différens
substances qui entrent dans ces combinaisons, ont les uns
avec les autres:' and he proceeds to explain the facts by
reference to Geoffroy's Table. And in Macquer's _Elements of
Chemistry_, which appeared a few years later, the 'Affinity
of Composition' is treated of as a leading part of the
subject, much in the same way as has been practised in such
books up to the present time. From this period, the word
appears to have become familiar to all European chemists in
the sense of which we are now speaking. Thus, in the year
1758, the Academy of Sciences at Rouen offered a prize for
the best dissertation on Affinity. The prize was shared
between M. Limbourg of Theux, near Liege, and M. Le Sage
{19} of Geneva[16\6]. About the same time other persons
(Manherr[17\6], Nicolai[18\6], and others) wrote on the same
subject, employing the same name.
