The Thanks of the 
Antwerp Zoological Society 
UR Society sgift of animals to the Antwerp 
Zoological Society brought forth a re- 
markably beautiful and original acknowledg- 
ment, addressed to Professor Henry Fairfield 
Osborn, President. The Royal Zoological So- 
ciety of Antwerp caused to be executed an 
illuminated memorial of thanks and apprecia- 
tion, printed with antique type dating back 
350 years, and illustrated with groups of 
animal pictures, in colors, printed from wood 
cuts that were made almost at the beginning 
of modern zoological literature. 
It is to be regretted that it is a practical 
impossibility to reproduce in this volume satis- 
factory facsimiles of this unique document, 
but its text is reprinted on the following pages, 
followed by the reply of Professor Osborn, 
A similar acknowledgment was executed and 
forwarded to the Director of the Zoological 
Park.
