I recently came accoss a set of victorian microscope slides at a flea market and was instantly hooked. I was partiularly fascinated by their sense of preservation within a visibly ageing form ( the glue used to fix the slide covered had yellowed and cracked. Presumably collected by an amateaur naturalist, the slides have sample ranging from rock fragments to the head of a blowfly ( pictured above).
Viewed through the microscope not only is the intended speciment revealed, but also the aging and flaws of the preparation.
The samples pictured appear to have a paper like consistency, reminiscent of old envelopes of pressed flowers - the stuff of memoried preserved for a later date the forgotten.
