Lane's Emulsion

Lane's Emulsion is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lane's Emulsion rather than just read about it. In short: Lane's Emulsion was a patent medicine manufactured in New Zealand. The emulsion, which had a strong fishy smell owing to its high cod liver oil content, was invented by Edward Lane, a chemist from Oamaru, in 1898.

Reference excerpt

Lane's Emulsion was a patent medicine manufactured in New Zealand.

The emulsion, which had a strong fishy smell owing to its high cod liver oil content, was invented by Edward Lane, a chemist from Oamaru, in 1898. In 1908 the company opened a new factory in the town's Harbour Street (now part of the Oamaru Historic Precinct) in a building which still bears the product's slogan "It's famous because it's good". The original recipe contained cod liver oil, beechwood creosote, mineral lime, soda, brandy, vitamins, fresh egg yolk and some secret ingredients. Sold in clear glass bottles, the thick cream-coloured liquid was fed to generations of New Zealand children and was also sold overseas. A branch factory was opened in Melbourne in the 1920s. Originally claiming to be "a reliable remedy for pulmonary ailments", the product was still in production until 1984. Oamaru company Crombie and Price, which bought Lane's Medicine in 1971, still holds the rights and recipe to the product. An ice cream based on the flavour of Lane's Emulsion was launched in 2014.

10. Lane's emulsion -otherwise referred to as Lane's revulsion - was manufactured by PSM Holdings. The formula contained chloroform which was no longer permitted as an ingredient by the late 1980's. Reformulation attempts to replace the chloroform with alcohol and preservative were unsuccessful as the bacteria grew on the egg yolks and the final batch did not pass microbiology tests and was sold aa bird feed..

Worked examples

Example 1 — a first encounter with Lane's Emulsion

Start with the simplest possible case. Write down what Lane's Emulsion 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 Lane's Emulsion 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 Lane's Emulsion 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 Lane's Emulsion

In research: Lane's Emulsion 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 Lane's Emulsion 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: Lane's Emulsion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health care in New Zealand, New Zealand stubs, Oamaru, so understanding it makes those chapters shorter.
In everyday life: Look for Lane's Emulsion 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.
