Arnold, of Savannah,at its last meeting, in Nashville, J)r, Posey, the reporter, notbeing able to attend the meeting. Appreciating its deep interestto the Southern Physician, and especially those of our ownState, in a statistical point of view, we begin its publication inour present number. The balance of the paper, relating to EpidemicDiseases, will find a place in our March number.Georgia certainly has no reason to complain—she has record*ed herself pretty fully in the last volume of our National Trans*actions,Report upon the Topography and Epidemic Diseases of the State ofGeorgia. By Jo#N F. Posey, M, P., of Savannah, Ga,The State of Georgia must, for purposes of medical topogra*phy, be divided into three unequal parts.The largest occupying more than half the area of the State,extends from the sea-coast and Florida line on the south to thehead of navigation of the larger rivers.The second division is separated from the first by a line be*ginning at Augusta, at the head of navigation in the SavannahEiver, and running nearly west-southwest, by Milledgeville andJ^acon, to Columbus, at the head of navigation in the Chatta*hoochee ; and is bounded on the northwest by a line drawnfrom the northeastern corner of the State, and running nearlysouthwest till it reaches the western boundary line of the State,about half way between Columbus and Nicajack, on the Ten*nessee Eiver.The third occupies all the space, within the State, lying northwestof the last mentioned line, and is much smaller than thesecond.The first division is, geologically, of tertiary formation, vary*ing in height and quality of alluvium according to the distancefrom the sea-coast.Dr. P. M. Kollock describes the part nearest to the sea thusu The topographical features of this district may be distin*guished into three separate orders, marked by strips or sectionsextending lengthwise from northeast to southwest.*' Commencing with the Sea Islands on the east, we remark aseries of sand-knolls or hillocks, apparently washed up by thegea from its bottom, varying in elevation, intersected by saltmarshesand creeks, and inclosing frequently brackish pondsand lagoons.
