Disease Signs in the Iris is intended for those who already have knowledge of the basic principles of irisdiagnosis. Part 1 is a translation from the German of the original work on iris interpretation by Theodor Kriege: Krankheitszeichen in der Iris. The disease signs are considered & explained as shown in original iris photographs. With few exceptions the conditions depicted have been confirmed by special methods of diagnosis, such as radiographic & blood investigations, as well as by the findings of surgical operations. The monochrome photographs especially highlight the structural changes & contrast values. The original text has been translated by A.W. Priest, & in Part 2 he correlates the iris findings with appropriate herbal & biochemical medication.
