WORKS ON NATURAL SCIENCE 



12. ELEMENTS OF CONCHOLOGY, or Introduction to 

 the physiology of Shells and their molluscous inhabitants, 

 their structure, calcifying functions and habits, geogra- 

 phical distribution, affinities, arrangement, and enumeration 

 of species, by LOVELL REEVE, F.L.S. To be completed 

 in twelve parts, size royal octavo, with numerous illustra- 

 tions, price 3*. 6d. coloured. 



"The work before us is designed to promote a more philosophical spirit of 

 inquiry into the nature and origin of Shells ; the grand truths that have been recently 

 made known in the physiological history of these animals are ably described and 

 illustrated ; and under the modest title of ' Elements,' will be found an interesting 

 and popular summary of conchological research. We may add, that few owners of 

 expensive cabinets of shells entertain correct ideas of the animals which formed 

 them." Ecclesiastical Review. 



(Under the Authority of the Lords Commissioners of the Admiralty.) 



13. FLORA ANTARCTICA, or Botany of the Antarctic Voyage 



of H.M. Discovery Ships Erebus and Terror, during the 

 years 1839-1843, under the command of Capt. Sir James 

 Clark Ross, R.N., F.R.S., by JOSEPH DALTON HOOKER,

 two vols., royal 4to., pp. 574, plates 200. Price 10 15*. 

 coloured; 11. 10*. plain. 



" The descriptions of the plants in this work are carefully drawn up, and much 

 interesting matter, critical, explanatory, and historical, is added in the form of notes. 

 The drawings of the plants are admirably executed by Mr. Fitch ; and we know of 

 no productions from his pencil, or, in fact, any botanical illustrations at all, that are 

 superior, in faithful representation and botanical correctness." Athenceum. 



14. CRYPTOGAMIA ANTARCTICA, or Cryptogamic Botany 



of the Antarctic Voyage of H.M. Ships Erebus and Terror. 

 In one vol., royal 4to., pp. 258, plates 74. Price 4<l. 4>s.

This is a separate issue of the Cryptogamic portion of the Antarctic 

 Botany, for the convenience of those Naturalists whose interest is more 

 particularly directed to that branch of the science.
