REPORT 



COUNCIL OF THE RAY SOCIETY, 



Read at the Eleventh Meeting of the Society, held at LIVERPOOL, Sept. %5th, 1854 ; 

 SIR CHARLES LYELL, F.R.S., IN THE CHAIR. 



IN presenting their eleventh Report to the Members of the Ray Society, the 

 Council feel that they are not employing mere formal expressions when they state 

 they have reason to congratulate themselves and the Members on the condition and 

 prospects of the Society. For many months, notwithstanding their continued efforts 

 to facilitate the publication of the works of the Society, they have been obliged to

 the sixth part of that work. 



During the past year, the Council has ordered to be distributed to the Members, 

 for the year 1853, the volume of ' Botanical and Physiological Memoirs.' This work 

 contains a translation of Professor A. Braun on ' Rejuvenescence in Nature,' by 

 Mr. Henfrey ; a Translation of Professor Meneghini on the Animal Nature of the 

 Diatomeae,' by C. Johnston, Esq., Lancaster, and an abstract of Kohn on the 

 4 Structure and Development of Protococcus pluvialis,' by Mr. Busk. 



In their last Report, the Council stated that the sixth part of Alder and Hancock 

 on the Nudibranchiate Mollusca would be the last. On account of the number of 

 new species discovered by the authors, and the extent of the general introduction 

 to the anatomy and physiology of the Nudibranchiata, it has been found utterly 

 impossible to accomplish the completion of this work in Part VI ; the Council have,
