20 INTRODUCTORY LETTER, 



And now having led you to the vestibule of an august 

 temple, which in its inmost sanctuary exhibits enshrined 

 in glory the symbols of the Divine Presence, I should 

 invite you to enter and give a tongue to the Hallelujahs, 

 which every creature in its place, by working his will 

 with all its faculties, pours forth to its great Creator:

 effectually, those objections to the study of these interest- 

 ing beings which I alluded to in the outset of this letter, 

 and this shall be the aim of my next address.
