CONTENT: | Peter Forsskål, in the capacity of botanist and zoologist, managed to amass an extensive herbarium during the scientific Royal Danish Expedition to Arabia in the early 1760s. The rare collection is today part of the Zoological department of the Natural History Museum of Denmark – consisting of 700 botanical species and 99 species of fish glued onto herbarium sheets. Noticeable is that Forsskål used the drying process of fish learned during his student years from Carl Linnaeus. It was a simple procedure and particularly suitable in hot climates. The fresh fish was dried for some hours in the sun until the skin could easily be removed from the body. All the flesh and fat was removed and there after the empty skin was glued onto a coarse paper. An economical method, which was easier to handle, store and transport, compared to when fish were preserved and kept in glass jars or bottles filled with spirits. This drying method has proved to be successful, evident due to the surprisingly good condition of his fish herbarium still mounted on paper 260 years later. |
