      title = {Two essays on the nature and wonderful properties of  Island Crystal. Essay I. Containing, all that has been  hitherto delivered in regard to its form, dimensions, and  double refraction of light; with the addition of several  new experiments with polished parallelopipeds and prisms  made of this substance, which discover a various, multiple,  and colorific refraction; and exhibit a variety of images  of one and the same object. To which is subjoined, a  computation of the magnifying power of reflecting  telescopes; and a table thereof, from 6 inches to 12 feet  in length. The whole illustrated with copper plate figures.  By Benjamin Martin. [electronic resource] :},
