Capitance

"Strategies such as juxtapositioning also served to highlight poetic and emotive qualities in fields not known for encouraging them, as in a cabinet curated by Langerman titled Capitance. This featured a range of instruments from the Physics department used to measure electrical currents (galvanometers, capacitors and Wheatstone bridges); a crystal goniometer measuring crystal face angles and crystal 175 from the crystal collection in Geological Sciences; M.R. Drennan’s models of the human embryo and a wax model of flesh; and a white tutu from the School of Ballet. In combining this selection of scientific instruments with a tutu, Langerman made allowance for the materials to be considered in a more poetic light, inviting the viewer to consider how a grand jeté defies the laws of physics, for example" (Liebenberg 2021: 186).

"A stainless-steel dilator from the Drennan collection, a carded set of glass slides of xenopus heart sections from the Medical Microbiology collection, a 19th century game called 'Frogs and Toads' from Special Collections and a wax model of an embryo, also from Drennan. This ‘amphibian’-inspired display showcases many qualities of the curatorial method, such as visual quotation (the combination of these materials foregrounds that the shape of the dilator resembles a frog), analogy (the wax embryo, dilator and frogs allude to the resemblance between sperm and tadpoles) and juxtaposition (the frog as a scientific topic dissected and contained in the slides, and the frog as a board piece in a game played by children)" (Liebenberg 2021: 183).

Pisces (Platichthys Fleus)

Addressing the fact that 95% of known animal species are smaller than our thumbs, yet natural history museums displays are filled with mostly large animals, this sub-museum shows the legs of a flea highlighting its muscles; a whole squid, just a couple of millimetres long; beetles that have been sliced along their entire length, through the antennae, head, legs and body — 1/10th of a millimetre thick; as well as these two baby flounder fish.

The Northern Lights

Histology slides of the brain (human and animal), scanned and converted into video projection

Icarus

Perspex wings with histology slides. Histology slides are prepared by taking a sample of biological tissue and fixing it to preserve the tissue in as natural a state as possible and prevent postmortem decay. The tissue is immersed in a chemical fixative and then embedded in wax to make it hard enough to cut into very thin sections of tissue (usually 5 to 7 micrometers in thickness). It is then passed through baths of solvents which remove the wax, then through graded alcohols, water and finally through baths of haematoxylin and eosin to stain it for better viewing under a microscope.

Perla Wings

Addressing the fact that 95% of known animal species are smaller than our thumbs, yet natural history museums displays are filled with mostly large animals, this sub-museum shows the legs of a flea highlighting its muscles; a whole squid, just a couple of millimetres long; beetles that have been sliced along their entire length, through the antennae, head, legs and body – 1/10th of a millimetre thick; as well as the wings of a Chrysopa perla, a fearsome predator in the insect world.
