wty: the finger should therefore be pressed all up the part* 



formtbuds. *** ^^ ^^'' assured that there is no branch on the point of 



shootina:; the bud will be felt us soon as the bark and find 



have made a socket or bed for its reception, which is don#> 



before the bud is half way on its journey: then a plaster 



fshould be prepared to cover the gush, without pressing it 



too close, but taking care to guard it well from the air, lest 



any should get in and cause a rot, more easily gained than 



cured. I have often (bund a bit of bladder, placed under 



the plaster, a better preservative than any thing el^e, if per- 



fe6^1y clean, and free from all grease. 



Difference of j promised at the conclusion of this letter to show the 



the flower bud ,.->, „ , _ 



and mixed difference ot the flower bud, and the leaf and flower bud, 



bud. wh'ch is very trifling. They both come from the same 



place— the line of life — and both in the same manner. In 

 the mixed bud, when arrived at its cradle, the rudiment of 

 the flower stops while the leaf is weaving. The first has 

 a:1so some few leaves to complete, and many scales. The 

 fcinale or pistil of both was a rude mass containing the 

 seeds, but nc»w begins to take its proper form; while the 

 xnales, all joined together, and proceeding from the wood,'' 

 are completely fashioned. The scales in the mean time are' 

 growing to coyer it thoroughly, and roost buds have a quan- 

 tity of their juices (that is the blood of the plant) lying be- 

 tween the several covers as a sort of resin, to ^^rptect it fron^ 

 the air and cold, of which it is now very susceptible. In the 

 mixed bud, the leaves always are finished ?jt the top, before 

 the flower, even where the flower comes out first, to prevent 



Various juic'i the matter of the leaf, or mixing with the juices of theflower; 



"f *^^ t^^ ^ ^^^^ ^^ ^^ ^® peculiarly evinced throughout the whole for- 



Mparat*. mation of plants; and which it is wonderful to me physio- 



logists have not observed, since their whole make is founded 

 on this principle— the keeping all their juices perfectly se- 

 parate. For this reason alt the vegetable world is formed 

 cylinder within cylinder; and, when there are holes, they 

 are so contrived, that nothing but air can enter them. I 

 shall soon exemplify this by delineations of the passage 

 between the stem and the peduncle; which plainly showr 

 how strongly this principle is maintained in every instance, 

 and hjow little therefore we can judge of the effect of th^ 



juices
