    Re: Transcription of Worsley's Log

    Well, what positions were on record for Elephant Island at that time? 
    Presumably Worsley was well aware that positions in this region could only be 
    trusted to the nearest five or ten nautical miles. That's good enough for 
    their purposes.
    
    Here are some quotations from an old guide book to the southern ocean (google a phrase to find it):
    
    First, the position of the cape:
    "Cape Belsham, north point of Elephant Island  60d 57' S 54d 56' W."
    
    Second, from the same source, some general comments on sources of positions 
    (it is not at all uncommon in the 19th and early 20th centuries to find that 
    the positions from Cook's voyage are still considered the best available):
    
    "7. South Georgia.-Adventure Bay, near the N.W. end of Georgia, and South of 
    Cape North, is given as described by Captain Weddell. The other points are 
    given from Captain Cook's Second Voyage, January, 1775.
    
    8. Sandwich Lands.-The Candlemas Isles, Cape Montague, and Southern Thule, arc 
    given in the Table from Captain Cook's Second Voyage, January and February, 
    1775; but Captain Biscoe states that the longitudes are about 50' to the 
    West, which we are apprehensive, requires confirmation.
    
    9. South Shetlands.-The position of these islands are generally 
    unsatisfactory, with the exception of Deception Island, the station of 
    Captain Foster's pendulum experiment*. A chart, published by the Hydrographic 
    Office, exhibits them much to the eastward, in some cases nearly to the 
    amount of 2�. In these high latitudes it is without doubt, a difficult task 
    to fix meridional distances, or absolute positions, with that degree of 
    accuracy that can be attained in lower latitudes and less rigorous climates. 
    In the absence of more certain authorities, we have repeated the positions as 
    given in the former edition." (printed c.1885, the "former edition" was from 
    the 1850s)
