DATES OF EATON’S FERNS OF NORTH AMERICA. 
Mary A. Day. 
Mr. W. R. Maxon has called my attention to the fact that there is 
no evidence in the two volumes of D. C. Eaton’s Ferns of North 
America that the work was issued in fascicles or that each complete 
volume was not published at a single date. In looking through the 
contemporary periodicals, however, I find notices from time to time 
of the publication of separate parts, twenty-seven having been issued 
between the last part of 1877 and August, 1880, when the work was 
completed. These notices were found in American Journal of Science, 
Botanical Gazette and Bulletin of the Torrey Botanical Club as fol-
