The article reviews four academic works published in 1934-1935. The first is a two-volume work by Alfred Hettner on physical geography, covering the hydrosphere, climatology, plant and animal geography, and human geography. The first volume discusses the hydrosphere and climatology, while the second focuses on the geography of plants, animals, and humans. The author notes that the work is valuable but could have been improved by including a section on oceanography. The second work is by Lucien Lévy-Bruhl, examining the primitive mind and its reactions to the supernatural. The third is a publication of biological data, including articles on the biology of chemical substances and allergy. The fourth is a laboratory manual for medical students, providing practical instructions in biology and biochemistry, though the diagrams are criticized as crude. The final work is a book on the identity theory, proposing a system of mathematical physics based on the idea that inertia, time, and space are measurements of the same thing. The author shows a strong grasp of physics and mathematics, though the book's conclusions are controversial. The article provides a detailed summary of each work, highlighting their strengths and weaknesses.The article reviews four academic works published in 1934-1935.
