Description: | Wooden hinged box containing two small upper shelves and a lower section. The lower section is filled with about 100 small bundles of different colours of wool, the upper shelves contain 9 small squares of coloured card, a pair of round lens glasses and 11 coloured lenses. Fixed to the inside of the lid there is a printed sheet with directions for use and the manufacturers address. The coloured lenses are fixed into grooves. The kit was used to test for colour blindness. The examinee would be asked to pick out all the similar coloured wool from the collection. If they can succeed in this task then they are cleared. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1889-1930 | Source: | University of Aberdeen | Creator: | E.B.
