NOTE OF ACKNOWLEDGMENT 



In view of the increased cost of publication and the consequent restrictions 

 in the scope of matter to be published in The Bryologist, particularly illus- 

 trations, it gives us pleasure to note that Mr. Beals has very generously defrayed 

 the expenses of making the cuts for the illustrations accompanying his article 

 on Torlula pagorum. — Editor.
