This hand-written document, labeled in different writing [By Newton H. Winchell], contains a brief and incomplete account of the Minnesota Academy of Natural Sciences' founding. The approximate date is 1890, as it refers to the 17 years of the Academy's existence. It includes a list of early members, first elected officers, and honorary members. The death of Dr. A.E. Ames, the Academy's first Corresponding Secretary, is noted. See the transcript for the full text.
This hand-written "Historical Sketch," labeled in different writing [By Newton H. Winchell], contains an incomplete account of the Minnesota Academy of Natural Sciences' 1873 founding and activities in its early years. The approximate date is 1886, as it refers to the 13 years life of the M. A. of N. S. It states that the Academy has 175 members, summarizes its museum specimens, and mentions its public lectures and a few scientific contributions. See the transcript for the full text.
