The following list of periodicals has contained so many 

 references to Ohio birds that it is not deemed necessary to 

 assign the particular references to the several years and au- 

 thors. Some of these periodicals have long since been un- 

 obtainable, some have ceased to be, some are scarcely out of 

 their swaddling clothes.
