 150th year of its growth, than it was between the 

 87 th and the looth year, befides the increafed 

 ineafure of its limbs not taken into confidcration. 



Were an accurate regifter to be kept of the 

 gro>Vth of oaks for 150 years together, (as ^n in- 

 genious correfpondent has wifbed) we fhould then 

 be at a certainty rerpe6littgit 5 and not depend 

 upon Gonjefture, as in the prefent inftancej but 

 in Which there being no intention to deceive, and 

 the inferences being fairly drawn from known cir- 

 cumftances, the conclufion cannot deviate widely 

 from the truth. 



^^ As the obviating pbjedlions is preferable to the 

 anfwering them, and the increafe of the branches

 to explain the principles on -which I proceeded. 



It is evident, that the contents of the limbs, be 

 their number more or lefs, amount in the whole to 

 the quantity of timber the fhaft would have 



contained^
