Because of Google for scanning this pioneering and widely-cited examine. Since this examine is monumentally essential to understanding honey bee dietary necessities, I’ve unsuccessfully tried to trace down any copyright holder for permission to share it. However as I perceive copyright legislation, since this reprint doesn’t comprise any indication of this pre-1978 publication being copyrighted, I consider that it’s permissible for me to put up it for noncommercial instructional functions. If there’s certainly a copyright holder, please notify me and I’ll instantly take it down.
