Its symbolic expression, to a numerical factor pres, is (Hbc) (Hbd) (Hcd) (

**bcd**), and it is clearly of degree 6.The summit C of the branch

**BCD**occurs at a percentage exactly corresponding to the formula Hg 2 T1.Then ABF = angle of elevation; EFB =quadrant angle;

**BCD**=angle of sight; EBF=ABF - ABE; and since ABE =**BCD**, it also equals ABF -**BCD**.The simplest invariant is S = (abc) (abd) (acd) (

**bcd**) cf degree 4, which for the canonical form of Hesse is m(1 -m 3); its vanishing indicates that the form is expressible as a sum of three cubes.Any line (" path " or " graph ") on the diagram, such as

**BCD**, represents an " operation " or " process " i.e.AdvertisementThus if a point of the body be displaced from A to B, whilst the point which was at B is displaced to C, and that which was at C to D, the four points A, B, C, D lie on a helix whose axis is the common perpendicular to the bisectors of the angles ABC,

**BCD**.
