Gave a bum five whole dollars

A woman was chatting with her next-door neighbor. "I feel really good today. I started out this morning with an act of unselfish generosity. I gave a five dollar bill to a bum."

"You gave a bum five whole dollars? That's a lot of money to just give away. What did you husband say about it?"

"Oh, he thought it was the proper thing to do. He said, 'Thanks.'"

Continuous-strip photographic film

In 1885, commercial production began of George Eastman's flexible, paper-backed photographic film, the first continuous-strip negative able to be compactly spooled. The film consisted of a layer of paper and a coating of insoluble sensitized gelatin emulsion, separated by a layer of soluble gelatin to enable release of the film layer after developing. He incorporated the Eastman Dry-Plate and Film Co., Rochester, NY, on 1 Oct 1884, and was issued patent No. 306,594 for this invention on 14 Oct 1884. He began promoting its convenience benefits to photographers over the bulkier, heavier and fragile glass plates then in use. Eastman designed the machinery for its manufacture, and a roll holder to use instead of glass plates.«[Image: Detail from an 1887 advertisement showing Eastman's negative paper on a roll and its package.]
