The Microscopic Structure And Mode Of Formation Of Urinary Calculi by Henry Vandyke Carter. This study presents a two-part investigation into the minute structure and genesis of urinary calculi. Part I documents the microscopic composition of stones, detailing nuclei and successive layers, and identifying constituents such as urates, oxalate of lime, uric acid, and phosphates, with numerous plates and careful observational data. The author notes the relative frequency and arrangement of these substances across various stone types and emphasizes the interrelation between organic (animal) bases and mineral components. Part II develops a conceptual framework for stone formation centered on “molecular coalescence,” exploring how colloids, cellular remnants, and environmental conditions influence crystal habit and morphology. The work argues that calculi are not simple precipitates but complex, structured aggregates with sub-morphous elements like globules, dumb-bells, spheroids, and laminæ arising through remodelling under specific physical-chemical conditions. Carter discusses diagnostic and preventive implications, advocating urine-focused strategies and gradual health improvements to deter stone growth. The volume is a pioneering synthesis of microscopy, physiology, and pathology from 1873.
