Photographs of Costa Rican Plants Vol. I, by Amelia Catherine Calvert. Photographs originally for Calvert's "A Year in Costa Rican Natural History". Two Volumes, 104 photographs. 1909-1910.
Vol. I contains the following insert on Morris Arboretum Letterhead, dated Sept. 24, 1979:
"These two books were presented by Mrs. Calvert, widow of Dr. Professor Phillip Calvert who was professor of Zoology at the University of Pennsylvania for many years. He was also Curator of Entomology at the Philadelphia Academy of Natural Sciences for a great many tears and was the world authority on Odonath (Dragon Flies). Both he and Mrs. Calvery were authorities on the flora and fauna of Costa Rica and wrote a book on the subject. These two books contain original photographs taken by Mrs. Calvert. Several species new to science are shown in this series of photographs.
In addition, the following note, on the same page, dated March 30, 1988:
"Dr. Daniel H. Janzen, professor of biology at the University of Pennsylvania, reviewed these books. Dr. Janzen conducts research eight months a year in Costa Rica, focusing primarily on plant-animal relationships and on ecologival restoration. He is considered an international expert in tropical ecology.
'Their primary interest would be for a historian studying Dr. Calvert...They are not of scientific value...One reason is the specific subjects chosen...If these had been photographs of landscapes and hillsides, the would have been quite valuable.'"
Calvert, Amelia Catherine
