Jason, I went through the Donald and Idella Gallagher Maritain bibliography, The Achievement of Jacques and Raissa Maritain: A Bibliography, 1906-1961, and could not find the article or the name Elie Gagnebin.
However, you may find something of interest in paragraph # circa 16 in the English version of the article at the website: http://www.professeurs-medecine-nancy.fr/Collin_R.htm
Also you may find Gilson's From Aristotle to Darwin and Back Again: A Journey in Final Causality, Species, and Evolution interesting. It's available from Ignatius Press and Gagnebin is listed in the index.
Yours,
B.
