the symbol of the religious cult of our sacred mushrooms. Following each entry 
in this sub-section Dr. de Borhegyi has added his illuminating comment. 
The third section in our Bibliography is ANTHROPOLOGICAL, reflecting 
the revivified interest in the ways of the Indians leading their own lives today in 
the mountains of Oaxaca, Puebla, Vera Cruz, and the vicinity of Mexico City. 
The fourth section is MY COLOGICAL. The fifth CHEMICAL, the sixth PHARMA- 
COLOGICAL, and the seventh psyCHOLOGICAL, PSYCHIATRIC, AND CLINI- 
CAL. The entries in these sections five, six, and seven often overlap, and therefore 
we have made them into a single list, but we have indicated in brackets to which 
sections each entry belongs. 
The eighth section covers PARAPSYCHOLOGICAL items; the ninth, CASES 
OF ACCIDENTAL INGESTION OF HALLUCINOGENIC MUSHROOMS; and 
finally BOOK REVIEWS are listed in the tenth section. 
Much has been published on our mushrooms and psilocybin in the lay press, 
in many countries. Our bibliography does not attempt to cover these articles: 
perhaps they will be the subject of a brief paper on a future occasion. We have 
tried to make our entries complete to July 1, 1962. 
The basic papers of Professor Heim that originally appeared in the Comptes 
rendus of the Académie des Sciences, Paris, were reprinted, except the most recent 
ones, in the Revue de Mycologie, complemented by specific definitions in Latin 
and certain other articles; and finally these pieces were gathered together in three 
recapitulations: 
(1) Notes préliminaires sur les Agarics hallucinogénes du Mexique, 1957, 
hereafter called Notes prélim ... ; 
(2) Nouvelles Observations sur les Agarics hallucinogénes du Mexique, 1958, 
hereafter called Nouv Observ ... ; and 
(3) Deuxiéme Supplément aux Observations sur les Agarics hallucinogéenes 
du Mexique, 1962, hereafter called Deux Supplé.... 
These were published by the Laboratoire de Cryptogamie, of the Muséum 
National d'Histoire Naturelle, 12, Rue de Buffon, Paris, V°. The successive pub- 
lication of these basic documents will be made clear by the key on the next page:
