a participation in them, and by the generous donation of a large 
part of his mineral collection.” 
There can be but brief mention of the great work done by 
Dr. Jackson during his days of active labor. He was the first in 
this country to establish a chemical laboratory for students, and 
many of the chemists of the last half century were indebted to 
him for their early instruction in the analyses of mineral bodies. 
Whilst engaged in such teaching he was the inventor of a pow- 
erful blast lamp for alkaline fusions, which was very serviceable 
before the street gas came into general use in laboratories. The 
earliest geological explorations in the region of Lake Superior 
were made by him, and the early State surveys of Maine and 
Rhode Island were under his direction. 
The scientific papers by Dr. Jackson, which appeared from 
time to time in the public journals, were numerous, and many of 
them of great interest and importance. The Society’s publica- 
tions have often been enriched by them. As early as 1834 he 
contributed an article to the Society’s Journal upon the Chiastolite 
or Made of Lancaster in this State, and this was soon after followed 
by others, giving the analyses of various minerals, and other 
information concerning them. From the time when the Proceed- 
ings of the Society were first published in 1841, to the period 
when he became enfeebled by illness, there may be found in its 
pages almost constant notice of the part taken by him in the 
discussions at the meetings, and frequently communications of 
much scientific interest, mostly upon geological or mineralogical 
matters, though they were not always confined to these. His 
contributions to Silliman’s Journal were likewise numerous. 
Among them may be found : Analyses of the Mineral W aters of 
the Azores ; Remarks on the Geology of Maine ; Chemical Anal- 
ysis of Meteoric Iron, Claiborne, Alabama ; Bituminization of Peat 
and its Conversion into Coal ; An Account of the Catlinite or 
Indian Pipe Quarry ; The Lava of the Volcano of Kilauea in 
Hawaii and its Chemical Composition ; Remarks upon Drift and 
upon the Organic Matter of Soils ; The Cancrinite Nepheline and 
Zircon of Litchfield, Maine ; The Ores of Lake Superior ; The 
Discovery of Tellurium in Virginia ; Analysis and Description of 
the Vermiculite of Millbury, Mass. ; The Lake Superior Copper
