A Hand-book to the Primates, Volume 2 (of 2)

In Short

This book is a scientific reference work intended to catalog the known species of primates. It moves methodically through the various families of Old World monkeys, anthropoid apes, and the fossil record, providing detailed descriptions of morphology, color, and habitat for each. Its enduring value lies in its role as a snapshot of late 19th-century zoological knowledge, capturing the era’s intense focus on biological classification and the burgeoning comparative study of anatomy between humans and their closest biological relatives.

The Story

The narrative arc of the book is defined by a scientific progression rather than a traditional story. It begins with an acknowledgment of the inherent difficulty of the task: the author notes that biological classification is an ongoing, incomplete project. He points out a poignant friction in the field—the reluctance of collectors to harvest specimens of primates because the animals’ distress and human-like gestures evoke such a deep, visceral sympathy in the observer. This tension between the cold requirements of scientific taxonomy and the emotional weight of studying "near-relatives" sets a somber, scholarly tone for the entries that follow.

The text then shifts into a rigorous, detailed catalog. It proceeds geographically and taxonomically, beginning with the Macaques, moving through the Guenons, Langurs, and the various species of Gibbon. For each animal, the author provides a technical breakdown: physical measurements, the specific hue of the fur, the distinctive patterns of the face, and the known range of the species. He describes the Crab-eating Macaque in its mangrove swamps and the Japanese Macaque in its northern habitats, often contrasting the animals’ behaviors in the wild with their temperaments in captivity.

As the book approaches the Anthropoid Apes, the tone shifts to a more analytical mode. The author pivots from mere cataloging to comparative anatomy, detailing the structural nuances of the Gorilla and Chimpanzee. He draws heavily on the work of contemporaries like Thomas Huxley, examining the brain’s convolution, the skeletal structure of the feet and skull, and the physiological similarities between apes and humans. He includes accounts of famous captives—such as "Sally" the chimpanzee—whose intelligence challenged contemporary notions of animal cognition.

The final movement of the book widens the lens to consider deep time. The author surveys the fossil record, evaluating the evidence for the earliest appearances of primates in the Miocene and Pliocene epochs. He treats these ancient findings with healthy skepticism, carefully distinguishing between legitimate scientific discovery and speculation. The book concludes with a massive, structured summary of the primate sub-regions of Africa and Asia, effectively mapping the known world of monkeys into a final, exhaustive index. It is a work that moves from the observation of the individual living animal to the systemic classification of the species, and finally to the vast, shadowy horizon of evolutionary history.

How It Unfolds

The ethical challenge of the collector The author acknowledges the emotional burden of studying primates, noting that their resemblance to humanity makes the act of collecting specimens an inherently painful task for the naturalist. He suggests that the "counterfeit presentment" of human features often inhibits the very research necessary to define these species.

The anatomy of the Macaque The text shifts to technical descriptions of various Macaque species, such as the Japanese Macaque and the Leonine Macaque. Each entry provides a clinical look at fur patterns, facial features, and the known geographical limits of their range, often highlighting the gaps in current knowledge.

Behavioral observations in the wild The author provides glimpses into the lives of these creatures, such as the Crab-eating Macaque’s penchant for swimming and diving for food. He juxtaposes these accounts with the often-unpredictable temperament these animals display when raised in captivity.

The comparative study of the Anthropoids The book moves toward the larger apes, focusing on the Gorilla and the Chimpanzee. It examines their skeletal and cranial similarities to humans, emphasizing the structural differences that define the limits of their physical capacity.

The fossil record and deep time The final section evaluates the ancient history of primates, scrutinizing the validity of Miocene and Pliocene findings. It presents a critical view of the debate surrounding early human remains and the evolutionary link between extinct apes and modern man.

The People

While this is a non-fiction scientific text, several figures emerge as the intellectual forces behind the data. Henry O. Forbes acts as the primary curator, the voice of authority who synthesizes the scattered reports of explorers, museum directors, and colonial consuls. He is a man of his time, driven by the Victorian impulse to document every corner of the natural world. Beside him stand the voices of observers like R. Bowdler Sharpe, who provides the editorial framework, and Mr. Gower or Consul Swinhoe, the field workers who translate local knowledge—sometimes mixed with folklore—into the raw data that fills these pages. These figures are not characters in a plot; they are the nodes of a global network of inquiry, each wanting to impose order on a chaotic, mysterious, and rapidly disappearing natural wilderness. Their shared desire is to close the gap between the known and the unknown, even as they realize that the more they study these creatures, the more complex and "human" the mysteries become.

In Its Own Voice

"There is a natural repugnance to collecting specimens of Monkeys on the part of sportsmen."

The author explains the professional and emotional conflict faced by those tasked with building museum collections.

"To shoot one feels like killing a sort of relation, and even our best collectors, who thoroughly understood the necessity of obtaining specimens in the interests of science, speak with a feeling of pain of the human-like distress which a wounded Monkey exhibits."

This reflection captures the late-Victorian ambivalence toward the emerging understanding of biological kinship with primates.

"The surface of the brain of a Monkey exhibits a sort of skeleton map of Man's, and in the Man-like Apes the details become more and more filled in."

The author quotes Thomas Huxley to illustrate the anatomical bridge between the primate brain and the human mind.

What It's Really About

At its core, this book is about the impulse to categorize the living world and the uncomfortable realization that the categories are never as rigid as we wish them to be. It explores the blurred line between "nature" and "humanity." The recurring theme is the search for order—the desire to create lists, maps, and anatomical tables that define species—intertwined with the unsettling recognition that these animals possess an inner life and a physical structure that mirror our own. It is a document of the intellectual struggle to maintain a scientific distance from creatures that, by their very existence, seem to challenge the uniqueness of the human form and spirit.

Why Read It Today

Readers with an interest in the history of science or the evolution of primatology will find this volume deeply rewarding. It offers a rare, unfiltered view of the 19th-century scientific mind at work—meticulous, observant, and occasionally caught in the contradictions of its era. You will feel the weight of the massive, leather-bound tradition it represents, where every color variation in a monkey’s tail was recorded with the gravity of a major discovery.

However, be aware that the book is a technical reference, not a narrative. It is dense with Latin nomenclature, synonymy, and descriptions of fur that may feel repetitive to the casual reader. Furthermore, the attitudes toward colonial exploration and the treatment of animals are distinctly of the 1890s, reflecting a time when the world was treated as a cabinet of curiosities to be collected and labeled. If you can navigate its Victorian formality and the dry, list-heavy structure, you will be rewarded with a profound sense of how we once perceived our place in the biological order. It is a haunting, informative, and beautifully precise artifact that reminds us how far we have come—and how much we have always been fascinated by those creatures staring back at us from the trees.
