SEA-FISHERIES LABORATORY. 273 



Now that this southward flow of water can no longer be 

 assumed, Matthews, forgetting apparently why Nielsen 

 postulated the anticy clonic circulation all around Ireland, 

 quotes him as postulating an anticyclonic circulation of the 

 water only off the south of Ireland (an eddy, that is to say) and 

 uses this as some sort of support for his own assumption of 

 an eddy in a cyclonic direction in this same Bristol Channel 

 area. 



The diagram I published, in the paper on the flow of 

 water through the Irish Sea already referred to, indicated an 

 anticyclonic eddy in the Bristol Channel which carried some 

 less saline water southward. 



I would like to point out that in the charts on which it 

 was based, which were published in the same paper, all the 

 results obtained by the Plymouth observers were included 

 and the actual salinities marked on the charts. The course 

 of the isohalines depended almost entirely on these results, 

 and not in any essential manner upon the few " liner " observa- 

 tions which were also indicated on the charts. Matthews, 

 no doubt correctly, objects to the inclusion of these latter 

 results as being less trustworthy ; but if they are left out the 

 course of the isotherms is not affected and Matthews' criticism 

 of the manner in which the charts have been drawn is not 

 really justified.
