412 THE JOURNAL OF BOTANY 
“Notes sur la Flore de la Laponie Finlandaise,” * in which he 
discusses many points lately brought forward; i.¢., dominant 
species, relation of the species one to another (using ten forms of 
denomination), the highest latitude attained by the species whether 
in the Salix region or others, relations to rock systems, and many 
other most interesting reflections. 
Then there is the chemical point of view with regard to peat- 
water (as in the difference shown by Mr. t in many Scottish 
lakes), the amount of calcium carbonate held in suspension, t &C. 5 
in fact, the phases of botany are so various that other sciences 
must be brought in as an aid.

topographical botany. I have yet to learn what is the use of the 
double designation of the locality by a number followed by a county 
name. is double-recording of the localities was, I believe, first 
brought into use by Mr. H. C. Watson in 1848, in what he called 
the third edition of his Geography of British Plants, of which only 
part i., ¢ Papaveracee, was issued. In it he divided Great 
Britain into eighteen districts, and each plant is accompanied by 
map and an enumeration in the double form, thus: Peninsula, 1; 
Channel, 2; Thames, 3; &¢. He elaborated this plan, omitting 
he maps, in his Cybele Britannica, published in 1847-1852; and 
subsequently he developed it into the form in which it now stands 
or 112 “vice-counties” in his Topographical Botany, first issued 
for private distribution in 1873-74, and published in a second 
edition in 1883.
