 that point, " Ovary superior" leads you to No. 158. ; 

 thence '* Flowers regular " to No. 159-; from that 

 you are conducted by " Ovary lobed " to No. 160. ; 

 where the " dotted leaves " fix your plant with the 

 Rue Tribe, to which it really belongs. 



Nothing can be more easy than the use of this 

 table ; and now that you possess it, I confidently 

 expect that you will say in your next letter, " Now 

 you have indeed shewn me the way out of my per- 

 plexities." Remember only that the table is not 

 contrived to meet all cases whatsoever, for a great 

 many Natural Orders are not even mentioned in it. 

 It is only framed to enable you to master such diffi- 

 culties as you, as a learner, may be expected to meet 

 with, either in fields or gardens.
