Sulphurs, Azures, Red Admirals, and Swallowtails are some of the butterflies observed at such "watering holes. Examples include Van Helmont's numerous careful determinations of specific weights and Starkey's work on mercury and antimony or his great project entailing thousands of experiments to discover a single method of developing all sulphurs into medicines.
