The public will without doubt be pleased to hear that Doctor JOSEPH LOVELL, who holds the highly responsible station of Surgeon General in the United States Army, purposes to give occasional abstracts from those reports, which are required to be made to him by all Surgeons of the ar my. They will be found to be interesting data from which to deduce the history of epidemic diseases, in so far as they depend upon atmospheric causes; and when those abstracts shali be accompanied with topogra phical descriptions of the various places to which they refer, they will combine such a body of information, on this important subject, as no other country, under any circumstances, could possibly furnish. We have subjoined the tables of comparative temperature and prevailing winds and weather for the first three months of the present year, and take great pleasure in publishing them, with the introductory remarks of Dr. Lovell, addressed to the Editors of the National Intelligencer, in the justness of which we perfectly coincide. MESSRS. GALES & SEATON, Washington, July 25, 1820. Should you find a place in the miscellaneous department of your paper for the publication of a monthly abstract of the meteorological observations made on the several military posts in the United States, it would, perhaps, be gratifying to the curious, and might, in time, become a useful document to the natural philosopher, as well as to the scientific physician. To the latter, especially, a series of observations, through a great extent of country, would be of the highest importance in ascertaining the effects of atmospherical changes, both occasional and permanent, upon the human system, and particularly upon certain formidable diseases, some of which, as the bilious remittent fever, arise about the same time at a great variety of places within a given latitude, while others, as the epidemic of 181213. commencing at a single point, traverse the continent with greater or less rapidity, usually taking, it is believed, a course from North and East to South and West. It has been presumed, and no doubt with good reason, that these complaints, especially the periodical ones, depend, in a great measure, upon sensible changes in the atmosphere; but observations have seldom been made to a sufficient extent, either as to time or place, to lead to any general and certain conclusions. Our military posts, at present, lie between latitude 29° 30, and about 45° 50′ North, and between longitude 70° 20′ to about 96° 42′ West from Greenwich, being upwards of 16° of latitude and 26° of longitude. The reports from which these abstracts are taken constitute a part of those required of the surgeons of the army; and, together with the returns of sick, the remarks made upon the causes, symptoms, and treatment, of diseases, as well as the medical topography of the several posts, may, perhaps, become a valuable document to the medical philosopher, especially should success attend an attempt to collect the bills of mortality from different sections of the country, with more detailed remarks upon the causes, rise, progress, and symptoms, of diseases, within smaller districts. These, however, are subjects too strictly professional to excite much interest in the public at large, and must, therefore, be confined to professional publications; in the mean time, many of your readers may be desirous of noting the effects of extensive cultivation of the soil, and increase of population, as well as local situation, with respect to large bodies of water, extensive prairies, forests, mountains, &c. upon the weather, in different parts of the country, at the same period, and the changes which take place at a given point in a succession of years; as it might lead to important practical results, relative to many things intimately connected with the economy of life, and which depend, in a great measure, upon climate. We observe, for example, that the mouth of the St. Peters is situated at a distance from any large body of water, and is surrounded by immense and uncultivated prairies and forests; that it is but a few miles North, and about 18° West, of Sackett's Harbour, situated near the outlet of Lake Ontario; and, at the former place, the mean temperature, at 7 A. M. in January, was 25° below that at |
