Aberdeen, without any qualification on the score of nativity 

 being added. In Gardiner's Flora of Forfarshire we find 

 this remark, " occurs frequently, though chiefly about the 

 habitations of man, and probably not indigenous." South- 

 ward from the preceding, the Elder occurs in nearly every 

 county, and is likely a true native in most of them. Under 

 such circumstances, it is somewhat of a puzzle to a botani- 

 cal geographer, whether he should take the actual northern 

 limit, or guess at the indigenous limit, in drawing up the 

 formula for illustrating the distribution of the species. The 

 Elder gi-ows at Killin, Perthshire, 150 yards of elevation ; 

 also at Kirkton, in Glen Clova, Forfarshire, 250 — 300 

 yards ; in all likelihood, introduced to both places. As a 

 strictly indigenous species, it may not rise above the mid- 

 agi'arian zone.

Denizen. Septal, Viatical, &c. " I believe the Dane- 

 wort to be a genuine native, but like Cynoglossum oflici- 

 nale, Atropa Belladonna, and some other plants, partial to 

 soils containing nitrate of potash," writes Dr. Bromfield, 

 " thus accounting for its frequent appearance about church- 

 yards, ruins, and similar places where that salt abounds,
