 sunny spots." He then gives some particulars of the 

 migration of quails, which was well known owing to 

 their excellence as food, as it is still on the Mediter- 

 ranean coasts ; and then goes on to mention many 

 animals which hibernate instead of migrating, e.g. the 

 snakes, snails, and many insects. 1 Then, returning to 

 birds, he proceeds : " Many kinds of birds also 

 hibernate, and they do not all of them go, as some 

 imagine, to warm countries. . . . For many Swallows 

 have been seen in holes almost stripped of feathers, 

 and Kites have been known to come out of such 

 places when they have first shown themselves. The 

 Stork, Blackbird, Turtle-dove, and Lark hide them-

 Macpherson drew attention to the similarity of these statements 

 and that relating to a captive Cuckoo hibernating in a kitchen, 

 described in Nature, vol. xliv. p. 223.
