THE HYDROGBAPHIC WORK IN THE IRISH 



SEA DURING 1909 : A POSSIBLE BEARING 



ON METEOROLOGICAL WORK. 



By Henry Bassett, Jim., D.Sc, Ph.D., Assistant 

 Lecturer in Chemistry in the University of Liverpool. 



The hydrographic work carried out by us in the 

 Irish Sea during 1909 has followed the lines indicated at 

 the end of last year's report.* Quarterly observations at 

 the 15 stations indicated on the chart (p. 186) have been 

 made, while additional observations at stations 1 to 7 

 were made half-way between the quarterly cruises, the 

 samples, as usual, having been collected by my colleague, 

 Mr. J. Johnstone, B.Sc. 



In the tables which follow, T°, CI °/ OOJ S °/ 00 , and <r t 

 have the usual meanings. 



A discussion of the results, which seem to be of 

 unusual interest, is given after the tables.
