Synopsis

This book provides a comprehensive dive into the anatomy of the Roman snail, examining its circulatory system through injections from various points of comparison to reach conclusive results. Past authors have provided a broad overview of these creatures but the author found much of it unsatisfactory. The snail is killed in a jar of cold water to preserve the foot and skin, then injected with various substances from the tentacle, aorta, or venous sinus. The author highlights the presence of capillaries throughout the animal's body, providing evidence for a closed circulatory system. Along with this feature, the author provides detailed illustrations and descriptions of all elements that make up the circulatory system such as the heart, veins and arteries. The work concludes with the significance of these findings to our current knowledge of Roman snails and extends our understanding of their circulation and biology.
