If the pitchers of Nepenthes, &c. are modified petioles, the cucullate 

 bracteae of Marcgraviaceae will be referrible to the petiole of the 

 bracteae." 



As I am now giving, in a connected form, the authorized abstracts, 

 admirably prepared by the Secretary, of all botanical papers read 

 before the Linnean Society, and as these abstracts of course appear 

 much earlier than any 1 could make from the papers when published 

 in the Transactions, I think it will be obvious that in this place I can 

 do little more than give the titles of the papers, in the mere catalogue 

 form adopted above. I cannot conclude this brief notice of a valuable 

 publication without expressing my sincere and fervent hope that the 

 task of recording the publication of these Transactions will in future 

 devolve on me more frequently.

 Illustrated with Plates. By Sir W. J. Hooker, K.H., LL.D., &c. 

 Part v., -or Vol. ii. Part I.' ' The Microscope and its Use, especially 

 in Vegetable Anatomy and Physiology. By Hermann Schacht. Ber- 

 lin, 1831. 8vo., pp. 198 and 6 plates.' The reviewer strongly recom- 

 mends this work ; he says, " It clearly explains all the details of the 

 processes of investigation, both with the single and compound micro- 

 scopes, and from the many practical hints it contains, it will be useful 

 nbt only to beginners but to experienced microscopists." 'Annals of
