The complete herbalist : or the people their own physicians by the use of nature's remedies : describing the great curative properties found in the herbal Materia medica, Vegetable.; Botany, Medical.; Medicinal THE COMPLETE HERBALIST. 295 ches, and the breadth two inches. The shape is oval, resembling a bean ; the position upright, and the fissure (or liilum) is directed to the spinal column. The upper end of the kidney is rather larger than the lower. It is covered by a strong ^^'^â ows capsule. The color is a reddish brown. Upon making a longitudinal sec- tion of the kidney, as represented in cut, two difiEerent structures are presented. The internal is of a darker color, and consists of about fifteen of what are called the cones of Maljjighi^^ which are arranged in three rows, the apex of each converging towards the hilum. This constitutes the medullary portion of the kidneys. The external structure is of lighter color usually, is ex- tremely vascular, and of a granulated ar- rajigement; it constitutes the cortical por- tion. The urine is formed in the tortuous tubes of the cortical substance,^ between whose walls are a number of small bodies called corpuscles of Malpighi. At the apex of each cone is the 'papilla renalis^ and in the centre of each papilla is a slight depression, called, foveola. Each papilla is surroimded by a small membranous cup, called infundibulum^^ into which the urine is first received as it oozes from the orifices of the papillae. Four or five of these infundibula join to form a common trunk, called calyx^^ and the junction of about three calyces forms a common cavity, called the pelvis,^ which is conoidal in shape, and from which proceeds the ureter,' the excretory tube of the kidney, which conveys the urine to the blad- der. The ureter is «?â cvlindrical tube of the size of a quill, with thin, extensible walls. It enters the inferior fundus of the bladder very obliquely, and opens by a verv small orifice. Just a
