Analysis of both internal and external evidence has yielded the following conclusions concerning this document: 

1. The July 22, 1850 Journal Letter is the first to be written after a silence of five months (see transcript pg. 1, paragraph 1), which indicates that no letter was produced from March through June, 1850.
2. This is an extremely important Letter, since it attempts to describe events at the Seminary during the turbulent year of 1849/50, and the health problems and ultimate collapse of Mary Whitman, Lyon's logical successor. See Elizabeth Green's 1979 biography, Mary Lyon and Mount Holyoke: Opening the Gates, pp. 311-316.
3. It is clear, from the opening pages of the Letter of Oct. 8, 1850, that the July 22, 1850 Letter immediately preceded it, and that we now have the Journal Letters produced for that period.
