      <abstract xml:lang="ru">
        <p>Это измерение абиэтиновой кислоты с t плавления +143°С., получено О. О. Кошелевым в лаборатории проф. Чугаева из раствора в этиловом спирте в виде бесцветных прозрачных кристаллов. Кристаллы принадлежат к ромбической сингонии гиногексагональнаго типа и имеют пластинчатый вид с наиболее сильно развитой гранью (0101) и почти всегда вытянуты по одному из двух направлений: или по оси [1000], или по оси [0121]. На всех наблюдавшихся кристаллах грани (0101) были сильно и совершенно неправильно изогнуты. См. рисунок и результаты измерений в статье.</p>

        <p>This is a measurement of abiethic acid with a melting temperature of +143 ° C., obtained by O. O. Koshelev in the laboratory of Prof. Chugaev from a solution in ethyl alcohol in the form of colorless transparent crystals. The crystals belong to the rhombic system of the gynohexagonal type and have a lamellar appearance with the most strongly developed face (0101) and are almost always elongated in one of two directions: either along the [1000] axis or along the [0121] axis. On all observed crystals, the (0101) faces were strongly and completely irregularly curved. See the figure and measurement results in the article.</p>
