No, XIV.— Professor Morren introduces this month’s contributions to natu-

an abstract of the history of the Vanilla planifolia, bearing large odoriferous 
fruits; a short digression on the introduction of Vanilla into domestic use ; 
a detailed description ofits cultivation; and remarks on the structure of this 
plant : the professor is certain that the V. planifolia is the same plant which 
is generally cultivated on the continent, and has produced at Li¢ége an abun- 
dant crop of odorous and delicious fruit. Mr. Beyrich’s memoir on the 
Goniatites found in the Transition Formations of the Rhine, exhibits the

a brief article on some new and rare Indian plants, Dr. Arnott describes th
