ADDITIONAL MEMBERS. DESCRIPTION OF NATICA HKLICOIDBS. 69 



The true naturalist seeks to discover the great laws of Nature : their 

 contemplation leads him to admire and adore the wisdom and power of 

 Him who has given them bounds they cannot pass, in their reproduc- 

 tion, preservation, and annihilation. He investigates their harmonious 

 connexion, their wonderful organization and powers, their uses, as they 

 conduce to supply his wants, relieve his cares, assuage his disease, em- 

 bellish his life, or add to his happiness. In their pursuit he finds health, 

 contentment, and peace. To him, the fertile vale, the barren heath, the 

 cloud-capped hills, and the dry and arid rock, furnish objects for his 

 study and delight ; and with a mind influenced by such feelings, he is 

 ready to exclaim, 



" These are thy works, O God, and they proclaim thy praise."
