    horizontal plane. Since every point upon the outline of an organ has been projected along a horizontal line parallel to the mid-plane from its position on the organ to the (anterior or posterior) surface of the body, it is necessary in order to see that point in its correct relations, to imagine that the eye is in the line of projection. The position of the eye must change, therefore, for every object viewed, and the projections do not represent exactly what would be seen if the body were transparent and viewed from a single point. The nomenclature adopted by the German Anatomical Society at its meeting in Basel, 1895 [BNA] is used in Plates I to XXV. The intervertebral discs are designated by Roman numerals; the number in each case correspond- ing with the vertebra above. The following topographic lines and directions are used: The midline of a section is a line passing through the middle of the sternum or linea alba anteriorly and the center of the body of the vertebra posteriorly. The midplane of the body is a vertical plane which contains the midlines of the sections. Upon the anterior surface of the body this plane would appear as a line passing through the middle of the sternum and the linea alba (anterior midline OO, Plate XXVIII) and upon the posterior surface as the pos- terior midline (OO, Plate XXIX). The midclavicular line is a vertical line through the middle of the clavicle, as seen in projection. It is about 8 cm. from the midplane. The midaxillary line is a vertical line through the apex of the axilla when the arm is in its normal position (OO,
