      <abstract xml:lang="ru">
        <p>Автор составил прилагаемую диаграмму, воспользовавшись, также, как и для диаграммы сферических коноприм, стереографическою сеткою, исключив из последней малые круги. Диаграмма коносекунд, также как и диаграмма плоских коноприм, построена на принципе подобий, то есть все подобные коносекунды приняты за одну. Главную цель диаграммы автор усмотрел в том, чтобы определить по отношению трех главных осей коносекунды те три конопримы, которые в коносекунде образуются в трех плоскостях ее симметрии.</p>

      <abstract xml:lang="en">
        <p>The author compiled the accompanying diagram, using, as for the diagram of spherical conoprims, a stereographic grid, excluding small circles from the latter. The diagram of conoseconds, as well as the diagram of flat conoprimes, is built on the principle of similarities, that is, all similar conoseconds are taken as one. The main purpose of the diagram is to determine, in relation to the three main axes of the conosecond, those three conoprimes that are formed in the conosecond in the three planes of its symmetry.</p>
