It will be seen by the above summary, that seeds of no less than 288 ge- 
nera, which illustrate 71 natural families, including too nearly all the kinds 
cultivated for culinary and other domestic purposes, have been collected, and 
to a certain extent tested. 
Many of the kinds show a considerable decrease in the comparative num- 
bers which vegetate after their periodical sowings, and a few kinds have ap- 
parently already ceased to germinate ; but some years must yet elapse before 
the subject can be sufficiently investigated to enable us to submit what we 
should consider a decided and satisfactory statement, respecting the limits 
assigned to the vegetative powers of the seeds in different genera. 
Examples of seeds belonging to any of the natural families not enumerated 
in the above Table, will be very acceptable, and may be addressed to Mr. 
W. H. Baxter, Botanic Garden, Oxford.
