doc#120 | hours. A very fine, gray solid (about 15 | g | ) is formed, water-washed by centrifugation |
doc#123 | Table 5-1. From an estimated mass of 25 | g | for a zero-magnitude meteorite, the other |
doc#123 | , Jacchia (1948) derived a scale of 0.15 | g | for a <formul>, zero-magnitude meteorite |
doc#125 | cellulose, containing 0.78 mEq of N<sol> | g | , was prepared in our laboratory by the |
doc#129 | bearing reguli <formul> and <formul>, and let | g | be a <formul> curve of order k on Q. A |
doc#129 | <formul>, whose lines are simple secants of | g | . On these generators let <formul> and <formul> |
doc#129 | which the corresponding generator meets | g | The line <formul> is the image of l. Clearly |
doc#129 | line can meets its image are the points of | g | . Hence the totality of singular lines is |
doc#129 | <bital>k<eital>th order complex of lines which meet | g | . </p><p> The invariant lines are the lines |
doc#129 | the lines of the congruence of secants of | g | , since each of these meets Q in two points |
doc#129 | <formul>, since an arbitrary plane meets | g | in k points. </p><p> Since the complex of |
doc#129 | <formul> which is not a secant but a tangent of | g | , for then any point on such a generator |
doc#129 | <formul> lines of <formul> which are tangent to | g | . Clearly, any line, l, of any bundle having |
doc#129 | generator of <formul> which is tangent to | g | at T. A line through two of these points |
doc#129 | bilinear congruence having the tangents to | g | at <formul> and <formul> as directrices |
doc#129 | of the lines which meet a twisted curve | g | . We now shall show that any involution |
doc#129 | must first show that every line which meets | g | in a point P meets its image at P. To see |
