The principles and practice of brewing
The Principles and Practice of Brewing, a 1907 London technical textbook by Walter J. Sykes and Arthur R. Ling, written for brewing students and practitioners. Its pictures are scientific plates: yeast cell drawings in two sheets, a chemical structure diagram of starch-related sugar units, and a magnified micrograph of a cell layer, useful for designers wanting clinical, early-twentieth-century scientific imagery with soft tonal shading.
