from sheer want of time. His Imperial Highness, my master, seeing tluit the 

 stoves of these royal gardens were not capable of containing the number of 

 exotic plants which he possessed, and that he could not gratify his ardent 

 desire of enriching his collection with new species, ordered two others to be 

 constructed, each of the length of 18' 10 metres, breadth, 6' 10 metres, and 

 of the height of 6"65 metres. They are to be heated by Perkins's method. 

 But I have been more particularly occupied in laying out a new botanic 

 garden for perennial exotics only. I have distributed them as you have sug- 

 gested in your Hortus Britannicus, in the Introduction to the Natural System. 

 I divided accordingly the whole area into six compartments, four of which 1 

 destined for Exogens, viz. three fc the subdivision Dichlamydeae, which com- 

 prehends the Thalamiflorae, Calyciflorae, and CoroUiflorae ; the fourth for the 

 subdivision Monochlamydeae ; the fifth was destined for the Endogens, and the 

 last for the Acrogens, Then I subdivided these compartments into as many 

 spots as there are orders or families which comprehend perennial exotic plants 

 that live in the open air, so that the surface of this garden (unquestionably 

 new for Italy, as all the botanic gardens which I have hitherto seen, and which 

 I know, are geometrically laid out) has the appearance of a geographical map 

 on which the empires, kingdoms, and principalities are laid down. 



During the last year the collection of these royal gardens has been much 

 enriched. I shall here transcribe, to avoid prolixit}^ only those trees and 

 shrubs which stand the open air. A^cev campestre laevigatum A. Brit., A. c.
