Question: Question: Were either of the men that Slater accompanied aboard the  HMS Shearwater born in Scotland? Passage:In 1874 he accompanied the botanist Isaac Bayley Balfour and George Gulliver aboard HMS Shearwater on an expedition to observe the transit of Venus on Rodrigues. In addition to studies of the flora and fauna, Slater excavated the subfossil bones of extinct birds, including the Rodrigues solitaire (Pezophaps solitaria) and Rodrigues starling (Necropsar rodericanus). His records were used by the zoologists Albert Günther and Alfred Newton to write the first scientific description of the Rodrigues starling in 1879. During a stay in Mauritius in 1875 he and George Gulliver explored the flora, the herpetofauna, and the aquatic avifauna. In 1885 he traveled with Thomas Carter to Iceland. Based partly on his work there, he wrote the Manual of the Birds of Iceland, published in 1901. In 1897 Slater described the short-tailed parrotbill (Paradoxornis davidianus) and the sulphur-breasted warbler (Phylloscopus ricketti). Together with William Bernhardt Tegetmeier and Frederick William Frohawk, he wrote the fifth volume of British Birds With Their Nests and Eggs (1898). In 1877 Slater was elected a Fellow of the Zoological Society of London (FZS). He was also a member of the British Ornithologists' Union.

Question: Question: How old was the Finnish Navy when it lost one fifth of its ships? Passage:On 4 May 1918, in the aftermath of the Finnish Civil War, Silatch arrived secretly in Kotka, Finland, to evacuate remaining members of the Finnish Red Guard. However, she was confiscated by the Finns and joined the Finnish icebreaker fleet as Ilmarinen, after the legendary hero from Kalevala. In December 1919 she was sent to Koivisto to assist three Finnish torpedo boats, C1, C2 and C3 that had been surrounded by ice some thick. The 150-ton torpedo boats had participated in the British campaign in the Baltic, and Admiral Walter Cowan had demanded that the Finnish squadron patrolling the area had to stay until the British forces had withdrawn. Despite the efforts of Ilmarinen, the weak-hulled torpedo boats were crushed by the ice, and the newly founded Finnish Navy lost one fifth of its ships. After the winter of 1919 Ilmarinen was laid up until she was returned to the Soviet Union according to the Treaty of Tartu. In turn the Soviets gave back the Finnish icebreaker Avance. The name Ilmarinen was later given to a Finnish coastal defence ship launched in 1931.
