of the Anatomy of the Squalus Maximus. 239 



EXPLANATION OF THE PLATES. 



(See Plates XVI, XVII, XVIII, XIX, XX, XXI, XXII.) 



Six of the following Plates are taken from drawings made 

 by Mr. Howship, who very kindly undertook that task, during 

 the indisposition of Mr. Clift, and his knowledge of anatomy, 

 which he has cultivated with much ardour, induced me to solicit 

 his assistance upon this occasion.
