T98 Dr Richardson'S Eemar'ks on the Climate and 
Hudson*’s Bay ; the Continent here being about 83° of long., or ' 
1000 miles wide. From Carlton House, the course, for 1000 
miles, was north, inclining to the west, to the mouth of the Cop- 
permine River, in Lat. 67° 4T N. Long. 1 15° J W, 
All the plants collected up to this point, amounting, Agamoe 
inclusive, to nearly 700 species, and to at least 5000 specimens, 
were brought home, and form the ground- work of the subjoined 
tables of natural families. About 500 miles of sea-coast, includ- 
ing the circumnavigation of the bays and inlets, were visited to 
the eastward of the Coppermine River, and the latitude of 68° 
18' N. attained at Point Turn-again ; but the whole of the plants 
collected during this part of the voyage were left behind, owing 
to the hardships encountered in the subsequent return across^ 
the barren grounds. This loss has been supplied, as far as re- 
gards the purpose of the present paper, by the collections made 
during Captain Parry’s second voyage in the same parallels of 
latitude, and at no great distance to the eastward. 
In making a few desultory remarks upon the circumstances*' 
which are likely to influence the vegetation of the districts, I* 
shall begin with their altitude above the sea ; and it is almost su- 
perfluous to remark, that v/e have few precise data on this sub- 
ject, and must for the present be content with rude approxi- 
mations. The line of country travelled through is destitute oF^ 
lofty mountains, table-lands, or ' great plains ; except that Carl- 
ton House may be said to stand on the northern boundary of 
sandy plain, which opening to the south, and extending to the 
confines of Mexico, is favourable to the migration of plants to 
the northward ; but our stay in that quarter being confined to 
ten days at the commencement of spring, during which only 
thirty species of plants were gathered, few of these southern 
plants find a place in our list. Few hills were seen during the 
whole voyage, rising beyond 800 or 400 feet above the level of 
the surrounding country, and none exceeding 800, except on. 
one part of the Coppermine River, where a range was observed 
to rise, on a rough estimation, to 1200 or 1500 feet ; but even 
this was free from snow in the beginning of July. 
Indeed, our route being by the great rivers, and almost un- 
interrupted water communications of the districts, was necessari- 
ly through the lower part of the country. Our barometer waS'
