8vo. XX pp, 199 pp. Contemporary gilt-tooled calf with vivid pink endpapers; spine sympathetically rebacked preserving original gilt-and-red title label. Signed by the author as a guarantee of authenticity on verso of title-page. An excellent copy, clean and fresh.
Rare sole edition of these early ‘Experiments and Reflections on the Caries of Human Teeth, with the Addition of a new Treatise on the Reproduction of Teeth in Rodents’. The chapters include arguments that wear from mastication alone does not cause caries; that acid alone does not cause them either; and various dismissals of other factors (temperature change, tartar, sweet substances, tobacco, etc.). Writing in the age before the discovery of bacteria, Lavagna has little to offer by way of positive suggestions for the origin of cavities, but remarks that they have become more frequent in recent times and attributes this to the widespread abuse of warm and cold beverages including coffee. He also offers several ‘cures’ and preventative measures, and even quotes from ethnographic reports by eg. Captain Cook on the sharpened incisors of the natives of Java.
The last 50 pp are devoted to the second section of the work, on the teeth of rodents. Here, drawing on his own experiments, Lavagna advances the theory - now confirmed - that the teeth of rodents continue to grow unless met with some opposition.
