Remarks upon Table XI.—The materials of the preceding Table are principally derived from the Botanical Appendix to Captain Franklin's Narrative, which has furnished upwards of 700 of the species. To these, 65 phænogamous plants have been added from Pursh, that were collected at Hudson's Bay by Tilden and others, and are preserved in the Sherardian and Banksian herbaria. The most northerly of Michaux's plants being collected to the southward of Latitude 53°, do not enter into our list; and the plants collected by Nelson and Menzies on the North-west coast, being from countries to the westward of the Rocky Mountains, and for the most part too far to the south, are also excluded. Thirty-three species, however, of phænogamous plants, from Mr Brown's Botanical Appendix to Captain Parry's first voyage, have been added to the column headed "Barren Grounds," together with seven from the herbaria made in Captain Parry's second voyage, and a few from Mr Brown's List of the Plants collected by Captain Ross, making the entire list in the Table amount to 840 plants.

The collections of Captains Parry and Ross compensate for the loss of the summer collection of 1821, in Captain Franklin's journey.

The structure of the Table is too simple to require explanation. The Woody Districts extend from Latitude 53 or 54° to Latitude 64° south, or nearly to Fort Enterprize. The Barren Grounds from Latitude 64° to the most northerly parts visited, or to 74°. By adding the plants in the last column to those in either of the two preceding ones, the whole vegetation of that district, as far as detected, is found.

The phænogamous plants in the preceding Table stand thus :

Barren Grounds.

there being 79 species common to the two districts.

The following families, as well as those distinguished in the preceding list by blank spaces in the column headed “ Barren Ground," were not observed to extend beyond the wooded district.

Table XII. is compiled from Table XI. The column headed" Lancaster Straits" is from Mr Brown's Botanical Appendix to Captain Parry's First Voyage, with the addition of two Crucifera and one of the Caryophyllea from his List of Captain Ross's Plants.

ART. II. Tables of Summer Temperatures observed in Spitzbergen by Captain FRANKLIN and Captain BUCHAN. THE following Tables of summer temperatures, observed during Captain Franklin's voyage to Spitzbergen with Captain Buchan, communicated to us for publication in the Philosophical Journal, are important, not only as connected with the climate of Spitzbergen, but also as illustrating some of the views taken of climate by Dr Richardson, in his very interesting and able memoir," On the Climate and Vegetable Productions of the Hudson's Bay Countries," also published in the present Number.
