1 Tn a previous chapter on this subject, in a “‘ Report of an Expedi- 
tion to Labrador in 1900,” published as a Bulletin of the Philadelphia 
Geographical Society, I unfortunately allowed a number of errors to 
occur, especially in exact nomenclature. I welcome this opportunity 
to atone for them as well as is now possible. I stated there that I had 
myself attempted only the more easy identifications, lying well within 
the capacity of the amateur; that, aside from a few special kinds, I 
had submitted my collection to Professor Bailey of Brown University 
for the correct naming of specimens; and that he had submitted all 
doubtful cases to Professors Robinson and Fernald of Harvard Uni- 
versity for approval or revision. In making these statements, I 
seemed to involve all these eminent authorities in responsibility for 
the errors that were included. But, through no fault of others, I 
received a mistaken impression as to the finality of many of Pro- 
fessor Bailey’s identifications, failing sometimes to distinguish be- 
tween his confident namings and his mere suggestions, and as to the 
extent to which they had received verification from the professors at 
Harvard. I now feel it a pleasure and a duty to apologize to these 
three men, who cannot be held accountable in any degree for mistakes 
that were due wholly to my own misunderstandings. ‘This case is an 
illustration of the difficulty met with by an amateur who wishes to 
describe strange and interesting places that he has seen, in guarding 
himself against error, and especially in attaching correct names to 
the objects he has observed. 
Since then Professor Fernald has kindly revised my collection, 
and tells me: “The plants are now correctly named, I think, with the 
exception of a few upon which I dare not venture a determination.” 
Space is lacking here to indicate all the changes that are necessary 
in my published list. SSome new names are secured, some individual 
numbers of plants must be credited elsewhere than as given. But 
mistaken conclusions in using the list may be largely guarded against 
by realizing that the following names are apparently all that need to 
be omitted entirely, or altered to another variety or species, or given 
a more modern nomenclature: Dicentra Canadensis, Draba nivalis, 
Lychnis apetala, Sagina procumbens, Dryas octopetala, Saxifraga 
Hirculus, Epilobium alpinum, var. majus, Archangelica, Aster radula, 
Taraxacum dens-leonis, Andromeda polifolia, Ledum latifolium, Pyrola 
rotundifolia et var., Vaccinium Canadense, V. Vitis-Idaea, Primula
