About This Collection

A collection of handwritten lectures on Conchology, consisting of an Introductory lecture followed by 15 topical lectures. They were written and delivered by William Wagner, founder of the Wagner Free Institute of Science, between 1852 and 1884. Conchology was one of Wagner's favorite topics and this was the first lecture series he wrote. He delivered it for the first time in 1852, prior to opening the Institute in 1855. The lectures' inconsistent paginations and paper sizes, along with many notations throughout, are signs of the many alterations he made to his lectures throughout the years.
