В двусторонней симметрии кораллов Rugosa прежде всего бросается в глаза и заставляет искать объяснения внешняя форма коралла— согнутого на подобие рога конуса. Еще Неймар (Die Stamme des Thierreichs) указывает на таковую форму, как на характерную для всей группы Rugosa. В данном мною объяснении строения Rugosa я исходил от впервые мною указанного факта бокового прикрепления кораллов Rugosa, так что в этом есть некоторое сходство с гипотезой Bernard'а. Ноя исходил из твердо мною установленного факта бокового приростания, при чем это приростание. является первичным, а не вторичным, как у Bernard'а, по предположению которого боковое приростание сменяет первичное осевое приростание, происходящее как бы с усечением острого конца.
On February 23, 1911, at the age of 65, the former director and honored professor of the Mining Institute, mining engineer Joseph Ivanovich Laguzen, died of a stroke. He did a lot of work on paleontology and geology of Russia. In paleontology, his works were varied, but were mainly devoted to the study and description of the fossil faunas of the Jurassic and Cretaceous systems. In 1887, he published good lithographed notes on the course of paleontology, and in 1895-1897 he published „A Short Course in Paleontology.” This is the first paleontology textbook published by a Russian professor. This work, in its significance, goes beyond the limits of the textbook, just as it went beyond the limits of the course taught at the Mining Institute. The article provides a list of scientific works of I. I. Laguzen from 1868 to 1891.
The strong and vivid image of Ivan Petrovich is still before our eyes; it is still difficult to come to terms with the bitterness that this is only an image, that Ivan Petrovich himself is gone. Having become a director, Ivan Petrovich did not seek to derive any special benefit from this for himself; he divided the director’s apartment into two parts and kept the worst one for himself; for example, he did not seek additional allocations for his assistants. He was a remarkably bright, original and richly gifted person.
