This book contains the complete original experiment by Andrew Crosse in the 19th century, along with a successful replication of his experiment by the London Electrical Society: In the year of 1837 Andrew Crosse endeavored to create synthetic crystal formations with silicates, water, and electricity. A couple weeks into the experiment, Crosse saw tiny crystal nucleations. Success, he thought. But, in the weeks to come he would notice something revolutionary. These crystal formations were developing the exact anatomy of an insect from the genus acarus! Eventually, these insect mineralizations dislodged from their rocky birthplace and began moving around. They even responded to external stimulus, such as light, implying that they developed some sort of sensory ability. Discover the meticulously detailed account of Crosse's scientific method that generated this curious living insects from dirt (silica)
