In the imperfect list herewith submitted I have frequently included works of which nothing is known save that they once existed. This is done for the purpose of calling attention to them, should any one of them be found in the hands of book owners and collectors here or abroad. Libraries like those of Mr. Lenox or of Mr. John Carter-Brown should be searched for such writings, and copies at least should be secured. The plan of Palenque, made by Bernasconi, in 1785, should also be copied without delay. A copy can be obtained from Madrid, by application to the Royal Academy of Spain.
