released ; of these three were recorded from the south coast of 

 Ireland, outside the Irish Sea area altogether, and two others 

 were stranded on the north east coast of Ireland, after making 

 comparatively long journeys. 



Five bottles were washed ashore during August, and 

 these were recovered on the Welsh coast. Four of them were 

 found within eight miles of each other on the Carnarvon Bay 

 Coast of Anglesey, three on August 24th and one on August 

 25th. The fifth was found further south, oft' Borth in Cardigan 

 Bay, on August 26th. These five bottles represent the Stations 

 I, IV, VI, VII, that is they come from the East, Centre and 

 West parts of the line upon which they were distributed. 

 Examining the Meteorological Office Reports for the Weather 

 Observation Stations at Holyhead and Dublin (Phoenix Park), 

 one station on each side of the Channel, it is seen that during 

 the period July 2nd to August 26th (inclusive), the following 

 statements may be deduced from the wind records : — 



Holyhead — 



The wind blew from a westerly quarter 33 more days than it did from 

 an easterly quarter. 



The wind blew from a northerly quarter 23 more days than it did from 

 a southerly quarter. 



Dublin {Phoenix Park)* 



The wind blew from a westerly quarter 24 more days than it did from 

 an easterly quarter. 



The wind blew from a northerly quarter 23 more days than it did from 

 a southerly quarter. 



Moreover, on the average northerly and westerly winds were 

 a little stronger than winds from opposite quarters. 



The directions of the prevailing winds were such that the 

 general surface drift of water due to them would be south- 

 east (true) in July and south-east by east (true) in August. 

 Finally, these bottles were recovered during a period of onshore 

 winds. 



* There are two other Meteorological Stations in Dublin l>u<. during the 

 periods under survey, their records are very similar t<> Phoenix Park.
