Step into the mid-nineteenth century to witness the thrilling convergence of pioneering chemistry, early photography, and modern industrial ambition.
In Short
Published in New York in 1851 by S. D. Humphrey and L. L. Hill, this periodical captures a pivotal moment when the daguerreotype was expanding from a novel likeness-maker into a widespread commercial and scientific art. The volume presents technical experiments on chemical reactions, discussions on printing photographic plates, and reports on telegraphic innovations alongside a vibrant commercial registry of galleries and supply houses. It endures as an authentic window into the meticulous craft, fierce rivalries, and sweeping industrial dreams of early photographic pioneers.
The Story
The volume opens with a rigorous scientific inquiry into the chemical changes bodies undergo in darkness and the nature of photographic agents, establishing an analytical tone rooted in experimentation. Robert Hunt investigates how vapors from iodine, bromine, and chlorine interact with polished metallic surfaces like silver, copper, and titanium, detailing the creation of colored rings and chemical films that mimic optical phenomena. This foundational exploration of chemical affinities flows directly into practical applications, examining how these delicate plates can be transformed into printable surfaces. Antoine Jean Claudet’s detailed specification reveals the complex process of treating daguerreotypes with mixed acids and ammonia, etching the plate so that it can yield numerous engraved copies. Expanding beyond the photographic plate, the journal chronicles contemporaneous industrial and scientific breakthroughs. It considers the feasibility of iron pavement as a durable alternative to traditional stone in the streets of Paris, detailing costs and electrical properties. A stark physiological experiment conducted by Professor Agassiz at Cambridge demonstrates the rapid and devastating toxic effects of strychnia on a young captive bear, noting unusual post-mortem decomposition patterns. The narrative shifts toward personal accounts and professional disputes as L. L. Hill defends his momentous yet controversial discovery of capturing natural colors on metallic surfaces against detractors, pledging to keep his process free from extortionate monopolies. The journal then surveys the expanding commercial landscape of photography across America, cataloging prominent artists, new gallery spaces, and technological improvements like Peck's plate holder and magical backgrounds that enhance portraiture. Interspersed technical studies examine the action of alkaline chlorides and air on mercury, calculating the exact proportions of sublimate produced under varying temperatures. The text documents the ongoing efforts to lay a submarine telegraph cable between England and France across the Straits of Dover, specifying the heavy gutta-percha and wire-roped cables designed to withstand heavy marine anchors. Detailed instructions for galvanizing daguerreotype plates using home-built or purchased batteries provide practical guidance for operators seeking better contrast and durability. The volume concludes with an extensive commercial registry, directories of apparatus dealers like the Scovill Manufacturing Company and Myron Shew, and advertisements for specialized cameras and plates. Through this progression from theoretical light-action and chemical bonding to industrial engineering, poison experimentation, and commercial enterprise, the journal constructs a comprehensive portrait of an era where art and science marched hand in hand toward a mechanized future.

The People
The volume features several key figures who drive its scientific and commercial pursuits. Robert Hunt and Augustus Waller want to decode the precise chemical mechanics of light and vapor interactions on metal. Standing in their way are the invisible complexities of metallic hardness, film resistance, and the elusive nature of chemical force; they end up mapping detailed classifications of colored rings and binary compounds. Antoine Jean Claudet wants to liberate the daguerreotype from its single-plate limitation by turning it into a mass-producible printing medium. The obstacle of acid damage to delicate highlights blocks his path, but through careful washing and electrotype reinforcement, he succeeds in creating a viable engraving method. L. L. Hill wants to share his revolutionary discovery of natural color photography with the world while protecting ordinary operators from extortion. Malicious rumors and financial exploitation stand in his way, leaving him defensive yet resolute in his refusal to monopolize his secret. Professor Agassiz wants to investigate the physiological mechanics of strychnia poisoning through controlled observation. The cunning resistance of a captive bear who rejects poisoned food complicates his experiment, but he ultimately documents rapid toxicity and peculiar post-mortem decay. Finally, commercial operators like N. E. Sissons and J. D. Wells want to build prosperous, stable businesses in their respective towns. Fluctuating market conditions and technical hurdles challenge them, but through hard work and advanced equipment, they emerge as successful proprietors of thriving multi-room galleries.
In Its Own Voice
L. L. Hill reflects on the heavy burden of public controversy surrounding his unprecedented photographic breakthrough.
