Xlii PROCEEDINGS OF THE 



the * Tuci,' for bringing the book to a conclusion in such an im- 

 perfect state. "It is," he says, "principally attributable to the 

 more than usual progress made of late years in the knowledge of 

 this branch of Natural History, which, by the numerous expe- 

 ditions in quest of science, has been extended to such a degree 

 that it is difficult to imagine what number of species may ulti- 

 mately be found; so that, though the present publication has 

 already far exceeded the limits originally contemplated, it ends 

 incomplete, leaving the feeling that our knowledge is in its in- 

 fancy, and that, till more is seen, the point which the author had 

 principally in "view, that of reducing the marine species in general 

 under natural families, in a well-organized system, cannot be 

 satisfactorily accomplished. Various attempts have, meanwhile, 

 been made to bring this interesting tribe of plants under a new 

 arrangement ; and one in particular, by M. Lamouroux, embracing 

 a comprehensive view of the subject, is entitled to great credit. 

 To these, however, the author is not ambitious of adding, but 

 rather finds satisfaction in taking leave of his readers, with the 

 consciousness of having laid before them a set of figures upon the 

 accuracy of which they may rely, and which, as representations of 

 things that are, will, through every change of human opinions, 

 retain an undiminished value, while they may serve, in the hands 

 of some abler and more fortunate successor, as the ground-work 

 of that which he had hoped to have accomplished himself." Such 

 successors (and Mr. Tvirner lived to hail the resixlts of their sy- 

 stematic labours) have been found in Agardh and Harvey, who 

 have not failed to record their obligations to the work thus briefly 

 noticed. 



The above-mentioned publications constitute, however, but a 

 small part of the services rendered to botany by Mr. Turner, as 

 Sir James Smith's ' English Botany,' and ' Flora Britannica ' and 

 ' English Elora,' and, we may add, the volumes of our own Trans- 

 actions can testify : he did stUl more, by encouraging in the 

 pursuit of science every young Naturalist who came in his way, 

 welcoming him to his table, assisting him by the use, and often 

 by presents, of books, and by advice and money, if needed. He 

 possessed an extensive library, rich in works on the Fine Arts 

 and Literature, as weU as in Botanical publications. He joined 

 with Mr. Borrer, so well known in our Society, in the preparation 

 of a work upon Lichens, of which only a small portion was printed, 

 for private circulation, extending to 167 pages, under the title of 

 ' Lichenographia Britannica,' but which, if continued as it Mas
