collected from Labiates, as that of Narbomie has the perfume of Lavender, 

 of Provence that of Rosemary, the flavour of that of Cuneo in Piedmont 

 being due to Ivy. But honey may also acquire toxic or medicative 

 properties, as that of the Eucalyptus. The honey of Moravia has a 

 terebinthine taste from the bees devouring the honey-dew of the Pines. 



Poisonous honey is especially characteristic of mountainous regions. 

 Tims Alpine mountaineers have died from eating honey collected partly 

 from the Aconite. Such accidents are very rare, as the bees prefer to 

 frequent gardens &o. 



Kahmas, Azaleas, and Rhododendrons have long been known to 

 supply poisonous honey. A. pontica and R. ponticum were probably 

 the species of which Xenophon wrote, describing how his soldiers were 

 poisoned bv honey, though none died. This occurred near the Black Sea.

Hybridisation, Recent Research into the Theory of. By 



C. Correns (Bot. Zeit. April 16, 1903, No. 8, p. 114-25).— A general 

 review of recent literature in this connection, acquaintance with Mendel's 

 theory being presumed and De Vries' Theory of Mutation omitted 

 pending issue of second volume and special review thereanent. Bateson 

 and Saunders' Report specially considered as most important next to De 

 Vries, but objection taken to new terms introduced. The publications of 

 Tschermak, Weldon, C. C. Hurst, Strasburger, W. A. Cannon, and 

 Millardet are reviewed and summarised. The reviewer, however, fears 

 that unless separate definite objects are distributed to, and reported upon 

 practically by, observers, the mass of literature is likely to lead to more 

 confusion of ideas than real enlightenment. On the other hand, he fears 

 that even such individual research as is recommended by Mr. Bateson 

 would probably lead to a mass of contradictory reports which would 

 baffle the student, and be little likely to lead to the predicted revolution 

 in our ideas of inheritance, species, and variation. — C. T. D.
