Part 1: The Projection of Lantern Slides" by Lewis Wright is an instructional treatise on the use of optical lanterns for exhibition and scientific demonstration, written in the early 20th century. The book delves into the various aspects of lantern slide projection, providing technical insights and practical advice for users ranging from educators to social workers. It aims to assist readers in selecting and utilizing different types of lantern equipment effectively. The opening of the work introduces the concept of lantern projection, categorizing it into two main branches: the projection of lantern slides and the scientific demonstration of opaque and microscopic objects. The author discusses the importance of different components of an optical lantern, such as the slide-holder, lens, condenser, light source, and the lantern's structural body. It emphasizes the significance of selecting appropriate lighting options, detailing the advantages and disadvantages of various illuminants like electric, acetylene, and oil-based sources. This foundational information sets the stage for more detailed exploration of individual lantern components and their functionality in subsequent chapters.
