Botany. 287 
While pursuing botanical studies at Paris, Prof. Brunet had noted with 
care, all the Canadian stations, in the herbarium of Michaux, and since 
his return he has been able to retrace every step of this hardy explorer 
and pioneer by means of his manuscript journals preserved by the Amer- 
iean Philosophical Society at Philadelphia. Attention was first called to 
this interesting manuscript, and an abstract given, in our vol. xlii (old 
series) about twenty-two years ago,—chiefly referring, however, to Mi- 
chaux’s explorations in the Alleghanies of the Southern States. In the 
present article we have a full account of the northern exploration, in the 
summer and autuma of 1792, with lists of some of the principal plants 
collected at each station, and useful notes upon the geographical distribu- 
tion or range of the forest-trees of the region. 
pon Michaux’s remark that the Gaultheria procumbens disappears 
about ten leagues above Lake St. John, Prof. Brunet adds a foot-note 
relative to the name of the physician of Quebec to whom Linnzus or 
Kalm dedicated this well-known plant. Kalm wrote the name Gaulthier ; 
hence Gaultheria, But, relying upon the French Academy of Sciences, 
ina volume of whose memoirs the name is written Gautier, Endlicher 
changed the orthography of the genus to Gautiera, Others have plau- 
sibly conjectured that his name was Gualthier or Gualtier, hence Gual- 
thieria or Gualtiera, But Prof. Brunet has settled the matter by refer- 
ting to the registers of the parish of Wotre-Dame de Quebec (e. g., 1751, 
Aug, 26), where the signature of this physician is found, written Gaul- 
tier, Gaulleria or Gaultheria, the original form of the generic name, is 
therefore not much amiss, and scarcely needful to alter; although Gaul- 
tera would be more correct, and may at length be made to prevail.
