through the inner bark, deposits a sub- 

 stance which becomes wood, and is found 

 to be attached in layers round the trunk. 

 These may be seen in trees cut trans- 

 versely asunder, and from which the age 

 of the trees, in many instances, can be 

 ascertained. There is also supposed to 

 be another deposit made of a quantity of 

 the same finer fluid, which is laid up at 

 the end of the season for the purpose of 

 being forced upwards in the spring ; and 

 this is supposed to be employed in form-

 is nothing more than the pulp, afford-

Having, therefore, ventured into an 

 examination of the different parts of a

 consideration, how much a body of so
