implied in the Nautical Magazine for 1852 in the case of a bottle 

 (No. 102) thrown over in November 1835 about forty miles south 

 of Cape Sable (Nova Scotia), and picked up in May 1836 on the island 

 of Fuerte ventura (Canaries). The distance traversed would not be 

 less than 3600 miles, which gives a daily rate of about twenty miles, 

 an estimate that is very excessive for the traverse of this part of 

 the North Atlantic, and it is likely that there has been a printer's 

 error here, as affecting the dates. 



One of the most interesting of the records for the Canary Islands 

 is given by Rennell in his work on the Currents of the Atlantic. 

 When in command of H.M.S. Hekla in lat. 58° 13' N. and long. 

 46° 55' W., about 140 miles S.W. of Cape Farewell (Greenland), 

 Captain Parry threw over a bottle, which rather over two years 

 afterwards (June 16, 1819, to July 29, 1821) was recovered on 

 Teneriffe. This is evidently the " enigmatical drift " (rathselhafte 

 Trift) to which Dr. Schott, quoting the Physical Atlas of Berghaus 

 (1837), alludes in his paper (p. 1). It does not, however, appear 

 to be quite so mysterious when we reflect that four bottles thrown 

 over by Captains Parry and Ross in Davis Strait, 1818 to 1821, 

 between 59° and 65° 40' N. lat., were found between eight and fourteen 

 months afterwards floating off and stranded upon the coasts of North- 

 west Ireland, West Scotland, and the Outer Hebrides. All of them 

 must have got into the main track of the Gulf Stream, and we have 

 seen in the earlier chapters of this work that Gulf Stream drift may 

 be stranded anywhere on the coasts of Europe between the North 

 Cape of Norway and Morocco, and that no inconsiderable portion 

 of it may be returned by the way of Madeira and the Canaries to 

 the West Indies. If, therefore, drift can reach the Irish and Scottish 

 coasts from Davis Strait, the passage of drift from Cape Farewell to 

 Teneriffe would be quite probable (see Note 35). 



Note 28 (p. 38). 



The bottle-drift of Madeira. 



All that has been said in the previous note of the Canary Islands 

 might be expected to apply to the neighbouring islands of Madeira, 

 which lies in the course of the same North African or Portuguese 

 Current— a current representing the southerly deflection of the great 

 North Atlantic easterly surface- currents that bear the Gulf Stream 

 seed-drift to Europe. Like the larger islands of the Canaries, Madeira 

 is ill-adapted for receiving and holding bottle-drift, and the records 

 are scanty. But they are sufficient to show that we have here the 

 same story of drift from the North-west Atlantic and from the seas 

 in European latitudes to the north of the island, none coming from 

 the south. 



The Prince of Monaco gives six records for floats that were recovered 

 in Madeira after being dropped overboard in 1885 and 1887 in the 

 region between the Azores and the Banks of Newfoundland. In 

 the American charts there is the record of a bottle (October 1908, 

 No. 4) which reached Madeira from a position about 400 miles due
