VI PREFACE. 



in many instances, to its genus ; though it should be borne in mind 

 that the characteristics given are applicable to the genera and species 

 described in the text, and not necessarily to all belonging to the 

 order. In addition to these analyses, a tabular view of all the 

 animals treated is inserted in the Appendix. 



It has not seemed best to define each term in the text, but the 

 Index is very full, and contains the explanation, definition, and refer- 

 ence of every ordinary zoological word used in the book. As far. as 

 possible, each scientific name is followed, in parenthesis, by its pro- 

 nunciation. To guide in pronouncing the titles of the cuts, the 

 quantity of the penult and the position of the accent are carefully 

 given. 



Ample directions to the beginner for collecting and preserving 

 specimens are given in the Appendix. These, with the hints in the 

 foot-notes, will enable the pupil to undertake the study of Nature 

 understanclingly. 



The present edition of "Fourteen Weeks in Zoology," not only 

 revised, but largely rewritten and entirely reversed in its arrange- 

 ment, though retaining those salient features that have given the 

 work such popularity for ten years, appears under the joint author- 

 ship of Professors Steele and Jenks, the latter being alone responsible 

 for accuracy of statement and the general plan of treatment of the 

 subject. The entire manuscript was read to Dr. Steele, the week 

 before his decease, and amended by most valuable suggestions from 

 him both as to the matter and the phraseology ; and the last literary 

 work of his life was that of writing a long letter to the Publishers, 

 approving the new arrangement and detailing his ideas in respect to 

 the typographical execution. Hence the work, as now presented to 

 those in our High Schools and Academies who are beginners in the 

 study of animal life, is hardly a posthumous book on the part of the 

 deceased lamented author, as it goes forth on its errand, stamped 

 with his living approbation. 



Many of the cuts were taken from nature ; the others were se- 

 lected from the works of Owen, Carpenter, Wood, Milne-Edwards, 

 Jones, Woodward, Claus and Sedgwick, the Pictorial Museum, etc.
