The following Lecture will especially want the quality of reality, 

 which no power of language could confer upon it. I must entreat 

 the friendly reader to take up a good map of the World, and the 

 excellent plates of Geographical Botany in the Physical Atlas of 

 Berghaus (and Johnston,) to supply the place of the demonstration 

 which so conveniently assists oral delivery, and I will readily allow 

 that perhaps a glance at those plates will convey a livelier impression, 

 and <nve rise to as much reflection as this Lecture.
