connection with their Geological Structure and Composition ; with 

 Specimens, and a Map of the Distribution of the Plants. In this 

 Essay the range of elevation, and the northern and southern limits 

 of the different species, should be attended to, and any facts tend- 

 ing to illustrate the geographical distribution of Plants carefully 

 recorded. It would also add greatly to the interest of the com- 

 munication if itwere accompanied with a coloured Geognostical Map 

 of the mountainous districts examined. — Time, February 1844.
