has Ijeen known to contain eight thousand ;* and a 

 single capsule of the Vanilla from ten thousand to 

 fifteen thousand.^ A single stalk of Zea Mays 

 will produce two thousand seeds;;}; a single plant of 

 Inula Helenium, or Elicampane, three thousand ; 

 and a single spike of Typha major, or Greater Cat- 

 tail, ten thousand. A single plant of Tobacco has 

 been found by calculation to produce the almost in- 

 credible number of three hundred and sixty 

 thousand ; || and a single stalk of Spleen-wort has 

 been thought, by estimation, to produce at least a 

 million of seeds.

 of them are precisely of the same character with 

 that of the conservative appendages already describ- 

 ed, except that they are of a finer and more delicate 

 texture, and demand no particular notice at present.
