380 APPENDIX. No. IV. 



Leopold the peculiar appearance which has been de- 

 scribed by different Polar navigators as " buttress-like," 

 " castellated ;" this appearance is produced by the un- 

 equal weathering of the cliff, which causes the hard 

 limestone to stand out in bands. Excellent sketches 

 of this remarkable appearance, drawn by Lieutenant 

 Beechey, are figured at page 35 of Parry's First Voyage, 

 'Hecla'and 'Griper,' 1819-20. The western side of 

 King William's Island (now, alas ! invested with so sad 

 an interest) is a good example of the low terraced form 

 which the limestone rocks assume at times.
