*The list as given is provisional for some species, as the reports upon which 

 their reputation is founded are very meager and sometimes even contradictory. 

 . . . They are here enumerated, not necessarily because it is believed that they 

 are poisonous, but with the view to eliciting more positive evidence either for or 

 against them. Although comprehensive, the list is incomplete, for experience ia 

 constantly adding to the number already known or suspected to be poisonous.
