 enbach. Query: Is Adonis autumnalis, wliich flowers in early 

 spring, in the corn-fields in Kent, and also rarely during sum- 

 mer, and wliich ripens and scatters seeds which flower in the 

 autumnal stubblefields, to be split into two, and the mothers of 

 the early flowering plants named A. verna, and the daughters, 

 or descendants, which sometimes flower in autumn, but the most

The first article in No. 2 of this useful periodical is called 

 "Notes on the Flora of the White Mountains, in its Geographical 

 and Geological Relations," by J. N. Dawson, LL.D., E.G.S, 



These mountains, which culminate both in their southern and 

 northern extremities, are part of the great Appalachian chain, 

 which extends from the north-east to the south-west of the 

 United States, and , is the, loftiest mpuatain-ranffe in North-, 

 Eastern America. . • ._,. i ., -.^r- ,+ '- - .-, -;.^;„-, -f. 



Their elevation is estimated at upwards of 6000 feet above 

 the coast- line. They form the great ridge, separating the sources 

 of the rivers which flow down the valley of the Mississippi into 

 the Gulf of Mexico, from those which flow eastward, into the 

 Atlantic. 



That part of the ridge or chaiji^ viz. the White, Mountains, 

 (their name is given them from their covering of snow, which 

 is not perpetual, but invests them during threeyfourths , of th^ 

 year,) is in the State of New Hampshire. :.'r-,f.;„,. , „^ or,o:+f>+ 



The following plants were collected during this excursion : —

 the pretty Mountain Tway blade. 



Close to the snow-line the botanizing party observed Gornu^ 

 canadensis and Linnaa horealis. The latter is reported to have 

 a vertical range of 4000 feet in this region.
