Scientific discovery can be unexpected and full of chance surprises. It is a naturally occurring compound, but mostly chloroform that exists in the environment is human-made. Chloroform usually collects in body fat; however, its volatility ensures that it will eventually be removed once the exposure has been removed. [13] Abiotic processes are also believed to contribute to natural chloroform productions in soils although the mechanism is still unclear. Soon, its popularity as an anesthetic soared to the point that it said that it was even used during the birth of Queen Victorias last two children in the 1850s. It is used in pesticide and film production.

[43], In May 1848, Robert Halliday Gunning made a presentation to the Medico-Chirurgical Society of Edinburgh following a series of laboratory experiments on rabbits that confirmed Glover's findings and also refuted Simpson's claims of originality. Chloroform can be very dangerous, to the point of being fatal to the victim if an inappropriate dose is administered or if the chloroform-soaked cloth is placed too tightly on their face. Its golden age, however, was short-lived, as it was gradually replaced by ether that was much safer than chloroform, and had virtually no side effects.
