of these species in the one island rather than in the'other, in con- 

 nection with the countries which they severally frequent, we shall 

 find, JLst. — That the exclusively American'species Elanus furcatm, 

 might be equally expected to visit either island ; 2nd. — That 

 Surniafunerea, being an inhabitant of the northern parts of Europe, 

 should rather be expected to occur in Great Britain (either in 

 Scotland or England) thaiyn Ireland; 3rd. — That all the others, 

 Neophron percnopterus, Vultur fulvus, Aquila ncevia, Noctua pas- 

 senna, and Noctua Tengmalmi, from their inhabiting (periodically 

 or permanently) the more southern portion of Europe, should 

 rather, on account of its comparative proximity thereto, be ex- 

 pected to visit England, than either Scotland or Ireland. Such 

 has partially, but only partially, been the result. Accidental 

 visitants cannot in such a point of view be placed under any 

 positive law.
