Digging Deeper into Helmont's Famous Willow Tree Experiment.
Hershey, David R.
American Biology Teacher, v53 n8 p458-60 Nov-Dec 1991
Author provides details about Helmont's experiment that was a milestone in the history of plant biology since it marked the start of experimental plant physiology. Concludes that Jean Baptista van Helmont's supposedly simple experiment becomes complex when trying to determine the methods he used, evaluate his sources of experimental error, and suggest more appropriate methods for testing his hypothesis.
