PROCEEDINGS OF THE ACADEMY OF 
By Alexander Wilcocks, M. D., "Researches on an Optical Illusion." 
During the year the By-Laws have been amended as follows : 
A new Chapter has been made, entitled Chapter XII ; on the Creation and 
Government of Departments. (See Proceedings 1858 p. 15.) 
Under these laws the Department A. has been organized and denominated 
the Biological Department. It has been in active operation since April last, 
and its contributions to the Proceedings of the Academy attest the zeal and 
activity of its members. 
The By-Laws have been also amended, as follows :
