Of the above specimens^ which were all introduced by seeds, the 

 three marked with a *' did not vegetate. Some species of i?6sa 

 and Crat^^'gus, not included in the above list, have vegetated, 

 but are not enumerated, as they have not yet flowered; and 

 consequently have not yet been named or identified. 



To enable our readers to take a general view of the various 

 details respecting introductions given in the preceding pages, we 

 shall next endeavour to generalise them first, numerically; and, 

 secondly, geographically. For the first object, we have had 

 from our Hm-tus Britannicus an enumeration made of the num- 

 ber of species introduced in each decade, from the beginning of 

 the 16th century to the end of the year 1830. We do not give 

 this enumeration as perfectly accurate; because many of the 

 species in our catalogue, as in every other, are doubtful ; but it 

 is not of much consequence whether it be perfectly accurate or 

 not; it is sufficiently so to show the ratio of the increase of the 

 introductions, from the earliest periods of which we have any 

 record of them, up to the present time.
