276 Lloyd's natural history. 



following record of Sperm-Whales observed on the coasts of 

 that island. The first record relates to three examples taken 

 during 1691 and the five preceding years on the western coast ; 

 while some years before 1750 another was washed ashore near 

 Castlehaven. A later writer, Young, states that about 1776, 

 examples of these Whales were not unfrequently seen in the 

 bays of the coast of Donegal ; while a large specimen was 

 stranded near Dublin in 1766, from which a quantity of sper- 

 maceti was obtained. Somewhere about 1773, aucther Sperm- 

 Whale appears to have been taken or stranded at Youghal ; 

 and yet another about 1822 in Connemara. 



In the case of such a casual visitor to our shores it will be 

 unnecessary to say anything about habits.
