that to the north of latitude 50°, Antarctic icebergs most abound 
between the meridians 15° west and 55° east. Mr. Towson, after 
an elaborate study, repeats the statement, but alters the limits to 
50° west to 10° east ; and the result of my own work would make 
these limits 50° west and 110° east. This, in itself, shews the 
greater area now affected and the necessity for some one to take 
the matter up. (See Plate 12). 
It is, I think, evident that for a convenient study of these 
records, one must have a chart, and I have marked each record 
in the same way, viz. by a small circle on the ship’s position 
at the time, each circle is marked with lines which shew the g 
the date. Thus: a circle with one vertical bar is for 1891; two 
bars, 1892; three bars, one being across, 1893 ; four bars crossed, 
1894; and a circle with a V in it, 1895; for 1888 a circle alone 
is used. The convenience of this is at once obvious when we 
come to use it. Each record also has a number, by means of 
which the original report can be found in the letterpress. 
T have had put on the chart another remarkable record—the 
track of the abandoned ship “ Dumbartonshire.” This extends 
from longitude 48° west to 14° 20’ east, nearly the whole of it 
being in latitude 40° The starting-point is in the iceberg region, 
and her progress therefore is the best possible guide to the direc 
tion and rate of motion of the icebergs. 
The several positions of the derelict are marked on the chart é 7

the ring has been in each case placed as nearly as 
the position in which she was seen, and these have been 
by a thick line. The derelict shews a very decided curren 
a region crowded by icebergs in 1892, nearly due east. 
icebergs followed the same course, their position in s 
years about the Cape of Good Hope and thence towards A 
would be fully accounted for. 
AS TO THE LOCALITIES OF THE ICEBERGS. 
It will be seen on the chart that a very large group of icebergs 
found soon after passing Cape Horn northwards, are near: #
