Contains a notice of a statement made by a gardener of Wis- 
ternitz, in Moravia, to the effect that since the establishment of 
a sugar manufactory in that place, the bees, pf which great 
numbers are kept there, have been annually destroyed to such 
an extent as to render their keeping quite unprofitable. The 
bees are attracted in the spring by the sweet odour issuing from 
the factory, on penetrating into which they are killed by the 
heat, or by immersion in the viscous fluid.
