Reference excerpt

On the Track of Unknown Animals is a cryptozoological book by the Belgian-French zoologist Bernard Heuvelmans that was first published in 1955 under the title Sur la Piste des Bêtes Ignorées. The English translation by Richard Garnett was published in 1958 with some updating by the author and with a foreword by Gerald Durrell. A revised and abridged edition was published in 1965, and a further edition in 1995. It is credited with introducing the term cryptozoology and established its author as the "Father of Cryptozoology."

Subject As one reviewer explained, it is a book "about animals that might exist." On the Track of Unknown Animals cites animals that had only been discovered relatively recently, such as the pygmy chimpanzee, coelacanth, Komodo dragon and giant panda; and those that are believed to have become extinct relatively recently, such as the moa and Tasmanian tiger. A major theme is that these animals were generally known to local peoples, but their stories were dismissed by visiting zoologists, particularly the okapi. The author then discusses evidence for mystery animals from all over the world including the Mokele-mbembe, sea serpents and the Yeti, with an extensive bibliography. He begins by complaining that "The Press has made such a laughing-stock of the Loch Ness Monster... that no scientific commission has ever dared tackle the problem" and ends with the wish that any new species are not merely slaughtered for trophies: "Have pity on them all, for it is we who are the real monsters." Reviewers praised the breadth of study, careful citation and the author's knowledge but it was criticized for being somewhat shallow and "overly long and rambling."

Worked examples

Example 1 — a first encounter with On the Track of Unknown Animals

Start with the simplest possible case. Write down what On the Track of Unknown Animals claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to On the Track of Unknown Animals before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about On the Track of Unknown Animals ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of On the Track of Unknown Animals

In research: On the Track of Unknown Animals appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses On the Track of Unknown Animals in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: On the Track of Unknown Animals is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 non-fiction books, French books, Literature about cryptozoology, so understanding it makes those chapters shorter.
In everyday life: Look for On the Track of Unknown Animals outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
