Reference excerpt

Hamlin's Wizard Oil was an American patent medicine sold as a cure-all under the slogan "There is no Sore it will Not Heal, No Pain it will not Subdue."

History First produced in 1861 in Chicago by former magician John Austin Hamlin and his brother Lysander Butler Hamlin, it was primarily sold and used as a liniment for rheumatic pain and sore muscles, but was advertised as a treatment for pneumonia, cancer, diphtheria, earache, toothache, headache, and hydrophobia. It was made of 50–70% alcohol containing camphor, ammonia, chloroform, sassafras, cloves, and turpentine, and was said to be usable both internally and topically. Traveling performance troupes advertised the product in medicine shows across the Midwest, with runs as long as six weeks in a town. They used horse-drawn wagons and dressed in silk top hats, frock coats, pinstriped trousers, and patent leather shoes—with spats. They distributed song books at the shows and in pharmacies. Performers included James Whitcomb Riley, singer and composer Paul Dresser from Indiana, and southern gospel music progenitor Charles Davis Tillman. At these gatherings, John Austin Hamlin delivered lectures replete with humor borrowed from the writings of Robert Jones Burdette. Grinnell College research points out that the Hamlins claimed efficacy for Wizard Oil on not only human beings but also horses and cattle, one poster displaying an elephant drinking the product by lifting the bottle with its trunk. Bottles came in 35¢ and 75¢ sizes. Carl Sandburg inserted two versions of lyrics titled "Wizard Oil" together with a tune into his American Songbag (1927). John Austin Hamlin would use the profits of Hamlin's Wizard Oil to found and manage Chicago's Grand Opera House. In 1916, Lysander's son Lawrence B. Hamlin of Elgin, by then manager of the firm, was fined $200 under the 1906 Pure Food and Drug Act for advertising that Hamlin's Wizard Oil could "check the growth and permanently kill cancer."

Worked examples

Example 1 — a first encounter with Hamlin's Wizard Oil

Start with the simplest possible case. Write down what Hamlin's Wizard Oil claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Hamlin's Wizard Oil 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 Hamlin's Wizard Oil 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 Hamlin's Wizard Oil

In research: Hamlin's Wizard Oil appears in biology 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 Hamlin's Wizard Oil 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: Hamlin's Wizard Oil is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1861 establishments in the United States, 1861 introductions, Alcoholic beverage brands, so understanding it makes those chapters shorter.
In everyday life: Look for Hamlin's Wizard Oil 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.
