Here alfo, as before, we are to find the limits of c the 

 greater quantity with refped to d the lefs ; and they appear to 

 be 6^ and 7^; of which 6d feems the more convenient. 

 Making therefore c=6 d\e^ there refults this equation, 



which by reduction becomes

Here alfo the limits of d being found to be e and 2 e ; 

 and 2 e being nearer the truth, make d—ie—f., and this equa- 

 tion refults,
