"Yet such has been shown to be the fact, and every improvement in the powers of the microscope has enlarged our ideas of the extent of animal life in the fluids of the globe; so that the philosopher is now ready to admit no limit to the possible minuteness of living beings, but looks to still further improvements in the microscope as a means of extending his acquaintance with them, and not as likely to set any bound to his inquiries."
William and Robert Chambers, eds. Chambers's Information for the People, New and Improved Edition (Edinburgh, William and Robert Chambers, 1842), Volume 1, p.534
The purpose of this online exhibition is to provide a resource of classic images that can take some time to track down. If you would like to suggest additional images please contact me alan@luminous-lint.com.
Thanks to Prof. Brian Stevenson for providing the Frederick Henry Evans and Alfred Reeves examples. If anybody has J.B. Dancer examples or a copy of his list of microscopic slides I would be grateful.
