 Academy of Sciences. This society was established in 1885 and 

 the publication of its Proceedings was begun in 1 89 1, the first 

 volume containing two papers by him. In that year he proposed 

 the undertaking of a biological survey of the state. The follow-

 in 1899 to publish a work entitled " Moulds, Mildews and Mush^ 

 rooms." The author's idea was expressed in the following 

 prefatory statement : " The increasing interest that has beer

 literature, has led the writer to prepare this introduction for 

 use of those who wish to know something of this interest

 years earlier, he had published his " Preliminary List of Alabama
