Reference excerpt

John Henry Lace (1857–1918) was a British botanist.

Biography From 1881 he worked extensively in the Forest Service of India and became its inspector-general of forests. From 1908 to 1913 he served as chief forest conservator in Burma. He made botanical collections in Afghanistan, Baluchistan, India and Burma.

While in Baluchistan he made an extensive collection of plants which resulted in the publication of "A Sketch of the Vegetation of British Baluchistan" by himself and Mr. Hemsley in Journ. Linn. Soc. xxviii. (1891) p. 288. He married Minnie Richbell. They had three daughters, Violet Sylvia (b. 1894 in E. India), Ethel Douglas (b. 1896 in Bengal), and Dorothy Mabel (b. 1899 in Bengal). In 1920 Ethel Douglas Lace married a grandson of General Sir John Watson.

Selected publications with W. B. Hemsley: "Sketch of Vegetation of British Baluchistan". J. Linn. Soc. 28: 288–327. 1891. List of trees, shrubs, and principal climbers, etc. recorded from Burma: with vernacular names (2nd ed.). 1922. Retrieved 3 January 2020. "List of Trees, Shrubs and Principal Climbers, etc, recorded from Burma 1913". Indian For.: 369–70. 1918. "List of Trees, Shrubs and Principal Climbers, etc, recorded from Burma 1913". Kew Bulletin (338): 341. 1918–19. "List of Trees, Shrubs and Principal Climbers, etc, recorded from Burma 1913". Proc. Linn. Soc. Lond.: 56–57. 1918–19.

Worked examples

Example 1 — a first encounter with John Henry Lace

Start with the simplest possible case. Write down what John Henry Lace 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 John Henry Lace 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 John Henry Lace 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 John Henry Lace

In research: John Henry Lace 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 John Henry Lace 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: John Henry Lace is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1857 births, 1918 deaths, 19th-century British botanists, so understanding it makes those chapters shorter.
In everyday life: Look for John Henry Lace 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.
