i 4 6 SCIENCE PROGRESS 



by Kidston (30) on the Lower Carboniferous plants derived 

 from the Arigna Mines, Co. Roscommon, is apparently the 

 sole contribution to Irish Paleobotany to be recorded. There 

 remains an almost untouched field for research among the Irish 

 rocks. 



The above notices, necessarily brief and in many cases 

 quite inadequate as indications either of the value, importance 

 or scope of many of the memoirs with which they are con- 

 cerned, may, however, serve to indicate the varied activities 

 during the last few years of those who are pursuing the study 

 of Carboniferous plants in this country alone. It is hoped 

 that this summary may be of use to others who may wish 

 to keep abreast of the progress that has been made in recent 

 years in this department of Fossil Botany.
