संवेदनशील क्रिस्टलीकरण प्रक्रियाएँ: रक्त में रचनात्मक शक्तियों का प्रदर्शन, एरेनफ्राइड फ़िफ़र द्वारा

It documents Pfeiffer’s sensitive copper-chloride crystallization method, in which added substances influence crystal forms and offer a picture-forming way to study qualitative characteristics.

Ehrenfried Pfeiffer wrote the book, Henry B. Monges translated it, and Professor Dr. Trumpp contributed the introduction.

It covers the production of sensitive crystallizations, experiments with healthy and diseased blood, further crystallization research, the effect of remedies on the patterns, and the method’s technical details.

It gives readers a concentrated account of one of Pfeiffer’s core picture-forming methods, joining practical technique with his interpretation of how formative qualities become visible in crystal patterns.
