PITTONIA. 
At the conclusion of the fourth volume of PITTONIA I was 
resolved, in view of the considerable loss of money involved in 
a publication distributed so almost gratuitously, to discontinue it, 
and said so to several of my friends. The appeals that have 
since come, for its continuation, from various botanists in 
several parts of the world, have induced me to offer still another 
volume ; and an instalment of Volume V will soon be ready. 
The price of Part 26, will be One Dollar. The publication 
will no longer be given in exchange, and will be sent only to 
such institutions and individuals as shall be enrolled on a new 
eee aeneae a emesa, ey 
_ Subscription list. The price of the whole volume will be Three 
Dollars. Nevertheless, as we make no promise to complete the 
volume within a year, it will be as well that only the price of 
Part 26 be sent in advance.
