1901, William Benjamin Carpenter, William Henry Dallinger, The Microscope and Its Revelations, page 22:In an equiconcave lens the foci are virtual and are crossed over; thus, the lens in fig. 25A is equiconcave, the focus F, instead of being measured from A to the right hand, must be measured to the left hand; consequently, § of the thickness must be subtracted from the focal length in order to determine the distance of F from the surface of the lens.
