If the fwallows of Europe, when they difappear 

 in thofe parts, retreat to the coaft. of Senegal, what 

 Heceffarily follows with regard to a Lapland 

 fwallow ? 



I will fuppofe fuch a bird to have arrived fafely at

 by ? Does it not alfo afford a moft ftrong prefumption, that 

 they were torpid during winter in the neighbourhood of this old: 

 hall?
