The Diatomaceæ of Philadelphia and Vicinity

"The Diatomaceæ of Philadelphia and Vicinity" by Charles S. Boyer is a scientific exploration that dives deep into the microscopic world of diatoms around Philadelphia. This book, probably from the early 1900s, shines a light on the many different diatoms found in fresh and salty waters, focusing on how crucial they are to both the food chain in the water and the overall health of the environment. The author looks at everything from where the Delaware River starts to how it flows into the sea, explaining how diatoms help us figure out water quality and the area's geological past. The extensive research covers an area 100 miles around Philadelphia, hoping to spark more interest in these tiny but important living things.
