TransactionsPublished under the care of the General Secretary and the Treasurer . electrons wander through space and are attracted by the positively-charged suns. It remains now to calculate the orbit of these electrons in order todetermine under what circumstances they fall back into the particle that enters into the solar system from infinite distancewith the initial velocity, v, describes a hyperbola around the sun asfocus and with the semi axis a, where t;2= X lO- X -1. The magnitude of the potential of these drops is 8 X 10-6 7 X 10-5 electrostatic units or A-olts. By the agglomeration of manydrops, the potential increases so foi* instance if 1000 drops unite, thepotential increases to volts. At first, after the union of many drops,the charge can disappear gradually under the influence of ultra-violetlight. This probably causes the single drops which cannot graduallylose their charge to retain it. ARRHENIUS: ELECTRIC CHARGE OF TEE SU^. 279 if a is expressed in a unit equal to the radius of tlie earths orbitand the unit of time is one Orbit, of electrified particle. If in the figure 8 represents the sun and TT the hyperbolicorbit of the particle, then AO = a. If we call the distance su ofthe sun to the asymptote of the hyperbola su =h, and put theangle SO U = !r, we get SO^ae, where e is the eccentricity of thehyperbola. Xow e cos ?f = 1 and, therefore, ae cos f= a ot OU = a. Further, ou = \ ^o^ — su = \ a^ e^ — 6^. If we call theperihelial distance SA = d, then d -\-a =ae = Va--\- h- ot d= Va^-^b— e is very nearly equal to 1, as in the cases which will be investi-gated below, we get: d=a (] and h= v = l, i. e., X 10 km in 86,400 seconds, or 1730 km ina second, we find a=2*^ X 10^ orbit radii, or 44,200 km. If, asin the experiments ol ijcnard, v = 3 X 10^ 300 then a is \-^) times greater, or 1,470,000 km. This is valid for heavy particles. In our case we have to regardthe electric a*;traction o
