In the volume of the " Proceedings of the Association of American 

 Geologists and Naturalists" may be found a description by Doctor 

 Jackson of the veins of tin ore of Jackson, New Hampshire, and re- 

 marks upon the zinc, copper, and lead ores of the same State. In the 

 subsequent volumes of the American Association for the Advancement 

 of Science he published: Observations on a Mirage seen at Lake 

 Superior; Remarks on the Geology, Mineralogy, and Mines of 

 Keneewaw Point ; On Ancient Pot-holes in Rocks ; Description and 

 Analyses of Allanite from Franklin, New Jersey ; Description of 

 Bismuthic Tellurium from Virginia ; Artificial Minerals from an Iron 

 Furnace of Pennsylvania. 



Doctor Jackson published also in the " American Journal of Agri- 

 culture," in the " Boston Medical and Surgical Journal," and in the 

 " Comptes Rendus of Paris." We are unable to make the catalogue 

 complete ; but the titles we have quoted are sufficient to give an idea 

 of the great extent and variety of the work which is shown even by 

 his shorter papers. But all this was subordinate to the extensive and 

 important Geological Surveys, on which he was early employed, and 

 of which he was one of the pioneers in this country. 



The first report of our late associate on the " Geology of the State 

 of Maine" appeared in 1837, and was followed by the second in 1838, 

 and the third in 1839. Additional reports upon the "Public Lands 

 of Maine " were likewise published in the two former years. In 1840 

 his final report on the " Geology of Rhode Island " was issued. In 

 18-11 his first report on the "Geology of New Hampshire" was 

 printed, followed by a second report in 18-12 ; and his final report on 

 the geology of that State was published in a quarto volume in 1844. 

 Lastly, in 1849, Doctor Jackson's report on the " Mineral Lands of 

 the United States in Michigan " appeared at "Washington in an octavo 

 volume with maps. It will be noticed that the geological work, whose
