THE AUTHOR'S PREFACES. 



M. Latreille, who, with the exception of some anatomical details, founded on my own 

 observations and those of M. Ramdohr, which I have inserted in his text, is its sole 

 author, will take upon himself to explain all that is necessary. 



As to the Zoophytes, which terminate the Animal Kingdom, I have availed myself, 

 for the Echinoderms, of the recent work of M. de Lamarck ; and for the Intestinal 

 Worms, of that of M. Rudolphi, intitled Entozoa ; but I have anatomized all the 

 genera, some of which have been determined by me only. There is an excellent 

 work by M. Tiedemann, on the anatomy of the Echinoderms, which received the 

 prize of the Institute some years ago, and will shortly appear ; it will leave nothing to 

 be desired respecting these curious animals. The Corals and the Infusoria, offering 

 no field for anatomical investigations*, will be briefly disposed of. The new work of 

 M. de Lamarck will supply my deficiencies. f 



With respect to authors, I can only here mention those who have furnished me 

 w^ith general views, or who were the origin of such in my own mind. J There are 

 many others to whom I am indebted for particular facts, and whose names I have 

 carefully quoted wherever I have made use of them. They will be found on every 

 page of my book. Should I have omitted to do justice to any, it must be attributed 

 to involuntary forgetfulness, and I ask pardon beforehand : there is no property, in 

 my opinion, more sacred than the conceptions of the mind ; and the custom, too pre- 

 valent among naturalists, of masking plagiarisms by a change of names, has always 

 aj)j)eared to me a crime. 



The publication of my Comparative Anatomy will now occupy me every moment : 

 the materials are ready ; a vast quantity of ])reparations and drawings are arranged ; 

 and I shall be careful in dividing the work into parts, each of which will form a 

 v.'hole, so that, should my physical jjowers prove insufficient for the completion of mv 

 design what I have produced will still form entire suites, and the materials 1 iiave 

 collected be in immediate readiness for those who may undertake the continuation 

 of my labours.

PREFACE TO THE SECOND EDITION. 



TiiK preceding j)reface explains faithfully the condition in which I found the 

 history of animals when the first edition of this work was published. During the 

 twelve years that have since elapsed, this science has made immense progress, 

 not only from the acquisitions of numerous travellers, as well-instructed as courageous, 

 who have explored ever)' region of the globe, but by the rich collections which 

 vario\is governments have formed and rendered public, and by the learned and
