There is also offered for sale, two complete sets of the late Prof. Clara E. 
Cummings’ exsiccati, Lichenes Boreali Americani. The sets comprise 280 
numbers and are particularly interesting from the fact that for the most part 
they are illustrative of Tuckerman’s specific conceptions. Originally pub- 
lished at $7.50 per century, they are now offered at $10.00 per set. In addi- 
tion to the foregoing, two incomplete sets, the numbers in each comprising 1 
to 140, 191 to 210 and 220 to 280, are offered at a price of $6.00 for each set. 
The prices are net. Make checks payable to, and address for further parti- 
culars regarding special prices if entire lot be taken, 
Mr. Walter C. Whitney,
