Meteorological Records

My own investigations have been mainly in continuation 

 of problems previously begun. Investigation of the heating

 A joint paper has been published as the second of a series,

Culture work has been continued with other species of 

 microscopic fungi and much information has been gained

 were hitherto not well known. 



Some time has been devoted to a revision
