1909] Robinson & Fernald,— Emendations,— I 35 
addressed to the Gray Herbarium and will always be gratefully 
received and carefully investigated. In general such corrections, 
especially if they relate to extensions of range, should be accom panied 
by specimens. 
Since the additional plants here mentioned as occurring within the 
range of the Manual were not actually included in the published 
work, it seems unwise to make on account of them any changes in the 
tabular summary on pages 23 to 27. Such statistical alterations of 
these tables can easily be made by users of the Manual if they desire 
to do so. 
Where the following errata seem to need explanation this 1s added 
in bracketed paragraphs. Lines are counted from the top of the 
page, but the line of running page-heading is not included in the count.
