February I placed two {mall onioris;*on a mus- 
lino ftrainer, in’ a glafs jar which’ contained 
azote and ftood in water.) They remained in 
this fituation nearly’ fix weeks without'altering 
the leaft in:appearance, ‘though fome’ bulbs’ of 
the fame kind, ftanding’in an open ’elafs on'the 
fame fhelf, vegetated vigoroufly before the ‘con- 
clufion of the experiment. | We'may ‘venture to 
infer from the two laft experiments, that what 
has ‘been hitherto”proved, refpeCing’ the! vege~ 
tation of feeds, is alfo applicable? to vthat ‘of » 
bulbs; with this difference: ‘that the former’ 
muft be prepared to make them fprout; by re-:

becaufe they naturally contain within themfelves:

Hence it happens that feeds, particularly fuch as 
are natives of temperate climates,)mdy be con-| 
veyed to a great diftance merely by,,guarding 
them’ from. humidity, which. cannot be done, 
with bulbs; for they foon vegetate, in‘ai proper
