About this sheet
The illustration features two primates and accompanying anatomical sketches of their skulls, indicating a level of scientific study:
1. **Colobe Guéréza** - This is the Guereza, also known as the Eastern black-and-white colobus. It is notable for its stark black and white fur, long bushy tail, and the mantle of long white hair that surrounds its back. Colobus monkeys are arboreal and native to Africa.
2. **Tarsier Spectre** - This likely refers to a species of tarsier, small nocturnal primates known for their large eyes, which are crucial for their night vision. Tarsiers have long fingers and an excellent grip, which is essential for climbing trees, as illustrated.
The print also includes two detailed sketches of the skulls of both animals, which would have been of particular interest to naturalists and scientists of the era, providing insight into the physiology and classification of the species.
The engraving is hand-colored, which was a meticulous and valuable process at the time, adding a significant aesthetic dimension to the scientific illustrations. The use of color helps to convey the natural appearance of the animals and would have made the volume a treasured piece for those interested in natural history.
