Alexandrine Petronella Frantina Tinne, a Dutch traveller, born at the Hague, Oct. 17, 1835, murdered in Fezzan, Africa, Aug. 1,1869. Her father was an English merchant, her mother the baroness Van Steengracht-Capellen of Holland. She was rich, travelled in Europe and the East, settled in 1861 in Cairo, and in 18(32 set out from Khartoom with a steamboat, transport vessels, beasts of burden, and a large retinue, to visit the White Nile. Her state made the natives believe her the daughter of a sultan. In 18G3 she explored the Bahr el-Ghazal, the W. arm of the White Nile, in company with Baron von Heuglin and Dr. Steud-ner, the latter of whom, together with Miss Tinne's mother, and many others, died from exposure. The expedition, which was absent 14 months, determined astronomically the position of Lake Meshera, one of the feeders of the Ghazal. The flora of the region has since been illustrated in Kotschy's Plantoe Tuinla-nce, partly from her drawings and descriptions. In 18G9 she set out from Tripoli for Bornoo, with 70 camels and 50 attendants, of whom the only Europeans were two Dutch sailors.

From Moorzook she turned aside to visit the country of the Tuariks, and while on the way to Ghat was murdered by her attendants.
