What chemical error did Conan Doyle make in the novel The Hound of the Baskervilles? - briefly
In "The Hound of the Baskervilles," Arthur Conan Doyle incorrectly described the chemical properties of phosphorus. He depicted it as glowing in the dark and leaving a luminescent trail, which is not accurate for white phosphorus under normal conditions.
What chemical error did Conan Doyle make in the novel The Hound of the Baskervilles? - in detail
In Arthur Conan Doyle's renowned novel, "The Hound of the Baskervilles," Sherlock Holmes and Dr. Watson are tasked with solving a mysterious case involving the legendary hound that haunts the moors around Baskerville Hall. While the story is captivating and filled with intricate details, there is a notable chemical error that Conan Doyle made in his narrative.
The error pertains to the use of phosphorus in the plot. At one point, Holmes deduces that the spectral hound seen by Sir Henry Baskerville was created using phosphorus. The description states that phosphorus can be applied to a dog's fur to create a glowing effect, making it appear as a ghostly apparition. However, this is not entirely accurate from a chemical standpoint.
Phosphorus does indeed glow in the dark, but there are several types of phosphorus, and only white phosphorus exhibits this property. White phosphorus is highly toxic and reactive, making it extremely dangerous to handle without proper precautions. It can spontaneously combust when exposed to air, which would pose a significant risk to both the dog and anyone handling it. Additionally, applying white phosphorus directly to fur would be impractical and hazardous, as it could cause severe burns or even ignite the animal's fur.
Moreover, the glowing effect of white phosphorus is not sustained over a long period. It tends to fade relatively quickly, which contradicts the prolonged glowing described in the novel. The use of phosphorus for such a purpose would be both impractical and highly dangerous, making it an unlikely choice for creating a spectral hound.
In conclusion, while Conan Doyle's "The Hound of the Baskervilles" is a masterful work of detective fiction, the chemical error regarding phosphorus serves as a reminder that even the most meticulous authors can make mistakes in their depictions of scientific phenomena.
