. Atlantic journal, and friend of knowledge [microform] : in eight numbers : containing about 160 original articles and tracts on natural and historical sciences, the description of about 150 new plants, and 100 new animals or fossils ; many vocabularies of languages, historical and geological facts, &c. &c. & Natural history; Indians; Sciences naturelles; Indiens. â¦Â» Ifr This mean heat of 50 degrees in springs and range of 99 degrees, is an additional proof that the interior of this continent is warmer than the coast and has a lesser range of variation, an usual concomitant ef- fect. Since Portsmouth in New Hampshire on the Atlantic ocean and the same parallel of 43 degrees as llochcster, nas a mean tenipya- ture of 44 and range of 110. Wnilc Detroit in Michigan, still farther west and also near 43 degrees, has 50| mean heat, with a range of 116. It must be added that Rochester and Detroit are both much above the level of the ocean and ought therefore to be colder on a par. FaraUel of 45 degrees latitude. 1. Portsmouth, level of the sea, 44 degrees mean heat, rangfe of 110 degrees. 2. Rochester, 480 feet above the sea, 45^ mean heat of the air, 50 of the springs, range 99. S. Detroit, 565 feet above the sea, 50j^ mean heat, range 116? i» tliis right? It is probable that the increase of mean heat and smaller range, is Eadual all the way from the At- ntic to the Pacific ocean; where a difference of 12 degrees at least in equivalent temperature and range is found. There the 52 degree of latitude being equal to the 40 de- gree, near Philadelphia or as warm. The 52 degrees of Europe is also equal to the 40 in China, the past- ern part of each continent being colder. But the different years often give variable results: thus this year, 1832. tiie winter has been very severe all over North America. The river Delaware was frozen at PliiladeN phia from the becinning of Decem- ber to the middle of February, wbich had not happened for nearly 40 years. I
