The Transactions of the Chicago Academy of Sciences is a scarce ante-fire imprint, with the following printed note dated Feb. 4, 1868 preceding the Contents: "The present Part of the First Volume of the Transactions of the Chicago Academy of Sciences, is the first of a series, which will be issued as rapidly as possible as materials accumulate, and provision is made for their publication. An apology is due to the contributors to this Part, for the delay in its appearance. This has been caused by the occurrence of certain unavoidable accidents, among which may be the fire at the rooms formerly occupied by the Academy, in which a large portion of the plates was destroyed, and the fire at the Printing Office, in which the same calamity happened to the text." The publication ceased after Volume 1, Part II, which appeared in 1869; most copies said to have been destroyed in the Great Chicago Fire of 1871.
