LESSON XXXIII. 



HOW TO ANALYZE A PLANT BY THE TABLES. 



272. Our readers are already informed that the Flora 

 which accompanies these instructions is not intended to 

 make them acquainted with the plants of the country, but 

 simply to teach the pupil how to analyze. Hence they will 

 not expect to find in it any thing like a full account of all 

 our flora, but a few plain exercises by which they may trace 

 every flowering plant in the country to its Natural Order, 

 about one in every two to its Genus, and about one in every 

 five to its Species. In conducting an exercise in this Flora 

 with a class of pupils who have well studied the former part 

 of the work, some method like the following Avould be inter- 

 esting and profitable. 



273. Suppose the class present, and each furnished with a spe- 

 cimen of some one unknown species, both in flower and fruit. 



Teacher. Are you all ready? Turn to the Flora and let iis find out to- 

 gether the family relations and the names of this fine pl-ant. We will 

 commence at the "Analysis of the Natural Orders" (page 132), and read 

 tlie first pair of lines, which we will call a couplet.
