All the illustrations of Uxmal and Sayil (there are none of Kabah or Labná) and a few related images in B. M. Norman, Rambles in the Yucatan: or, Notes of Travel Through the Peninsula, including a Visit to the Remarkable Ruins of Chi-Chen, Kabah, Zayi, and Uxmal (New York: J. & H. G. Langley, 1843). I have scanned these from a copy in the Library of Southern Illinois University, with appreciation.
