il INTRODUCTION 
Report, issue nothing of value to a botanical library and appar- 
ently are not interested in botany or related sciences. These 
have been stricken from the exchange list. On the other hand, 
the receipt of this number of the Annals is an indication that 
the Missouri Botanical Garden desires to continue the old 
exchange arrangement, the new journal being sent four times 
a year in place of the old Annual Report. Additional exchanges 
with publishers of journals dealing directly with botany are 
desired. Upon request, the monthly BULLETIN will be substi- 
tuted for the Annals as an exchange with those desiring a more 
popular and general account of the work and scope of the 
Missouri Botanical Garden.
