VERTIGO. 



Fertige, as Du CARNE DE BLANGY calls it, is 

 supposed to arise from the bees extracting the 

 honey of deleterious plants. I have treated fully 

 upon this subject under the head of Pasturage. 

 In addition to what has been there stated I will 

 give an extract from DR. BARTON'S Paper, who 

 after observing that there is more poetry than 

 philosophy in the following lines of Pope 



" In the nice bee what sense so subtly true 

 From poisonous herbs extracts the healing dew?" 



says : " It is however much to be questioned 

 whether this noxious honey proves so to the bees 

 themselves." Sir J. E. Smith asserts that " the 

 nectar of plants is not poisonous to bees." Syl- 

 labus to Botan. Lect. And Dr. Barton, though 

 disposed to adopt the contrary opinion, gives 

 instances to the same effect. Thus a party of 

 young men, induced by the prospect of gain, 

 having removed their hives from Pennsylvania to 

 the Jerseys, whose vast savannahs were finely 

 painted with the flowers of the Kalmia angustifolia, 

 could not use or dispose of their honey, on account 

 of its intoxicating quality ; yet, " the bees increased 

 prodigiously," an increase only to be explained by 

 their being well and harmlessly fed.
