of a new Method of Arrangement of the Orders of Exogens, and Ob- 

 servations on the Structure of Ovaries consisting of a single Carpel." 



Dr. Drunmiond has four papers ; the first (iv. 211) is in reference 

 to the observations on his views of botanical systems, contained in 

 a notice of Hooker & Arnott's ' British Flora ; ' the second (iv. 309) 

 is on Natural Systems of Plants ; the third (iv. 360) is entitled 

 " Casual Remarks on Morphology," and combats the doctrine as now 

 generally held ; and the fourth (iv. 365) is a reply to a review of his 

 * Observations on Natural Systems of Botany.' 



Dr. Vriese's note (iv. 215) on the temperature of the male inflores- 

 cence of Cycadcous plants, is the record of a remarkable and unac- 

 countable fact, well worthy of further investigation. 



Dr. Balfour (iv. 230), in the report of a meeting of the Botanical 

 Society of Edinburgh, has some remarks on the glandular stipules of 

 Cinchonaceae, detected in twelve species : the glands were found to 

 secrete a gummy fluid, and in some species this secretion was beauti- 

 fully coloured. 



Dr. Lankester (iv. 288) read a paper at the last meeting of the Bri- 

 tish Association for the Advancement of Science (for the report of 

 which I am indebted to the pages of the ' Botanical Gazette '), *' On 

 the Theory of the Formation of Wood and the Descent of the Sap in 

 Plants ; " and a discussion followed in which Professor Henslow, Mr. 

 Huxley, Prof. Asa Gray, and Dr. Lankester took part. 



Mr. Luxford has some valuable observations (iv. 292) on the struc- 

 ture of Ascidia and Stomata of Dischidia Rafilesiana, penned more 

 particularly with reference to the paper by the late Mr. Grifiith on that 

 subject, lately published in the ' Transactions of the Linnean Society,' 

 and from which some lengthened extracts are given at p. 265. 



Mr. D. Moore, of the Dubhn Glasnevin Garden, contributes a valu- 

 able paper (iv. 345) on the formation of wood in plants, detaiiing the 

 result of a series of experiments made in the Gardens between the 

 years 1830 and 1851.
