330 NOTICE OF THE LIFE OF JOSHUA ALDER, ESQ., 



1845-55, by the Ray Society, has obtained a name and a cele- 

 brity for its authors which will last as long as the study of 

 Natural History shall be held in honour, and its praise is to be 

 found in every published treatise on that science. The Zoolo- 

 gical portion of the work is the joint production of the authors. 

 We owe the anatomy and splendid plates to Mr. Albany Hancock. 



Each of the authors of the Monograph on the Nudibranchiata 

 had the honour of being presented by Prince Albert with a copy 

 of " The Natural History of Deeside and Braemar," composed by 

 the late Dr. Macgillivray, edited by Dr. Lankester, and which 

 had recently been printed by command of Her Majesty for the 

 benefit of Mrs. Macgillivray. 



On the Continent the Monograph was highly appreciated, and 

 its authors were made honorary members of the Imperial and 

 Royal Botanical and Zoological Society of Yicnna. 



Another and similar work " On the British Tunicata," to be 

 published by the same admirable Society, has been for some time 

 in preparation by the same authors. Of this, unhappily, Mr. 

 Alder has not been spared to see the completion, though he was 

 at work upon it at the commencement of the attack that termi- 

 nated in his death. It is gratifying to know, however, that he 

 had accumulated a vast amount of material on the subject, and 

 has left a beautiful series of drawings illustrative of the species. 

 His collection, too, of specimens in this department of Natural 

 History is, there can be no doubt, the most extensive in Great 

 Britain. In the hands of Mr. Albany Hancock the work is now 

 steadily progressing, and no doubt can be entertained that, when 

 published, it will be found a worthy companion to that on the 

 Nudibranchiata. 



As Mr. Alder's writings on Natural History are too numerous 

 to be readily noticed separately and commented on at this time, 

 it has been thought advisable simply to add to this notice an 

 entire list of them with references. Some it will be seen have 

 been translated into French or German. 



For this list the Club is indebted to the care of the Rev. A. M. 

 Norman, of Newbottle. 



The papers are upwards of fifty in number, and it may be
