Varieties of Localitij. 65 



the limits of their geographical distribution ; the result, v»hut- 

 ever it may be, of the researches we have here indicated, must 

 be registered with care, and cannot fail to lead to consequen- 

 ces of very great interest. 



Finally, we invite the zoologists of the expedition to search 

 for the analogies which may exist between the Fauna of the 

 elevated parts of the Scandinavian Alps, and that of the low 

 regions, more removed towards the north, which traverse the 

 same isothermal line. Such relations have already been no- 

 ticed by various authors in different regions, among others by 

 M. Latreille in relation to Sweden itself as compared with our 

 Alps and Pyrenees ; and they are of so great interest, that we 

 ought to endeavour, by similar observations in other places, 

 to confirm them and generalize them more and morie. 



Additional Notes to the Zoological pari of the Instructions 

 given bi/ the Academy. 



Some of these notes are designed to complete, others to illustrate in va- 

 rious points, the zoological instructions which have just been read. I at 

 first drew them up, not for the press, but the personal use of the zoolo^ 

 gists of the expedition, to whom they were given in manuscript. While 

 placing them here, at the request of M. Gaimard, I musf premise, that 

 ttiey have not been submitted cither to the commission nominated by the 

 Academy, nor to the Academy itself. They therefore appear in this place 

 solely on the personal responsibility of the reporter. 



Note A. — On the Varieties of Locality. 



Being obliged to confine myself to narrow limits in my report, I could 

 not insist so much as I desired on varieties of locality, and on the im- 

 portance of studying them profoundly at tlie present time. The follow- 

 ing extract from the Introduction to the Zoological part of the great work 

 on the Morea, will sujjply what I was unable to state formerl^^ The 

 question, in fact, presents itself in exactly the same light when we com- 

 pare Greece with France, and France with Scandinavia, insomuch that the 

 passage about to be quoted, although written about the animals of Greece, 

 is applicable in every respect to those of the southern and middle regions 

 of tlie Scandinavian peninsula. 



" Since natural history, enriched by the discoveries of numerous tra- 

 vellers, embraces at once in its immense field, the beings of all the coun- 

 tries of the globe, naturalists, for a long time accustomed to the inspec- 

 tion of the animals and plants of their own countries, have made distant 

 regions the habitual subjects of their most profound study. New Hol-
