viii PREFACE. 



With excellent opportunities of studying the habits and 

 movements of living cephalopods, and with dead specimens 

 of these animals on the table before me, I have followed, 

 scalpel in hand, the minute description of their anatomy 

 given by Professor Owen, in his masterly treatise in the 

 " Cyclopaedia of Anatomy," and by De Ferrussac and 

 D'Orbigny in their splendid monograph on the same 

 subject ; the two great sources from which almost all, 

 if not all, subsequent writers have drawn much of their 

 information. Quotations from other authors will be found 

 duly noted. 



I am indebted to my friend Mr. Thomas Davidson, 

 F.R.S., &c., for the beautiful portrait of the Octopus, 

 which forms the frontispiece to this volume ; to Mrs. 

 Edward Harris for the drawing of its eggs (fig. 6) ; to 

 Miss Gertrude Woodward for that of its tongue (fig. 4) ; 

 and to Messrs. West and Co., and Mr. Charles A. Ferrier, 

 for the care they have respectively bestowed on the 

 lithographing and engraving of the illustrations.
