quires, they meet with an oppofition occafioning this 
fiownefs infinitely more prejudicial than the precipita- 
tions. 
§ 26. The difference then which there is between a 
pinion that is too large, and one that is too fmall, is, that 
the firft will occafion irregularities, but never a ftoppage 
whereas the latter will produce both the one and the 
other : confequently, if one had no choice between thefe 
extremities of error, it would be better to declare in fa- 
vour of the fmalleft. 
§ 27. Might it not with juftice (as an ingenious clock- 
maker obferves) be objected to us, how ufelefs a thing it 
is to determine the right proportion in the relation of 
the diameters, whilft the fame defedt of proportion fub- 
fifts in a much higher degree in the general inequality 
of 
arcboutement qui occalionne cette lenteur, infiniment plus prejudiciable que Ie$ 
precipitations. 
§ 26. La difference done qu’il y a entre un pignon trop petit ou trop gros eft 
telle, que le premier caufera bien des irregularites mais jamais d’arrets, au lieu 
que le dernier prodnira l’un et Pautre, par confequent fi Ton n’avoit d’autres choix 
que ces deux extremites de vices, il vaudroit mieux fe declarer en faveur du. 
plus petit. 
§ 27. Ne feroit on pas fo.nde (comme le remarque un horloger de genie) a 
nous faire la legitime obje£tion, de Pinutilite qu’il y a a determiner la jufte pro^ 
portion dans le rapport des diametres, tandis que le meme vice de la dilproportion 
fubfifte a un plus haut point encore, dans l’irregularite generate de la diviiion des,
