    Letter from Antoni van Leeuwenhoek to Henry Oldenburg.
    Van Leeuwenhoek is trying to understand how the humidity/liquid circulates in a tree. He observes small holes in the cross cuts of branches of an oak tree. He imagines these holes to be pipes running through the entire tree (like a tube, as in his drawing) and wonders how water can go from the bottom to the top.
