This is one of the earliest photographs of the original King's College and Columbia College building. It is also one of the last views of the building at 40 Park Place before the move to 49th Street and Madison Avenue in 1857. According to the label attached to the copy on the left, Moore gave the photograph to the College Organist, Dr. W.H. Walker, who then transferred it to the College Library in 1887. The other copy of the photograph correctly identifies the photograph's subject "Columbia College" but has flipped the numbers of the date (1854, not 1845). 

Residence of Clement Clarke Moore (CC 1798) on the south side of West 23rd Street. The first two photographs are identical, with a woman and two men standing in front of the house. The last photograph is taken from a different angle and shows a man on the grand steps and another man in the side porch.

De Rham House was located on Fifth Avenue and Ninth Street (24 Fifth Avenue). The De Rham family purchased the house in 1850.  Before that, it was known as the Brevoort Mansion, the home of Henry Brevoot, Jr.  While these two photographs are taken from the same angle, they are not identical. The one on the right features a man standing at the entrance of the house.

The photographs below all seem to be taken from the same house on what was then known as Hudson Square or St. John's Park. The house was most likely on Hudson Street, on the westside of the Square, just above Hubert Street.
