scientific facts as the results of their ascents. We may notice 

 specially that of Francis Clissold on 18th August, 1822. That of 

 Marckham Sherwillon 26th August, 1825 ; of Auldjo, on 9th August, 

 1827 ; and of Dr. Martin-Barry. Since 1844 the ascents have been 

 numerous, and at the end of 1863 the actual number has risen to 171, 

 of which three were made in June, thirty-six in July, eighty-four in 

 August, forty-seven in September, and one in October. The extreme 

 dates are 1st June, 1858, the ascent of J. Walford ; and the 9th 

 October, 1834, the ascent of M. de Tilly, who came back with his 

 feet frozen, and suffered for a long time from this rash attempt at an 

 advanced period of the year. 



The author then gives an account of a scientific ascent made by 

 himself in 1844, with his friends Auguste Bravais, a naval lieutenant, 

 and Auguste Lepileur, a doctor of medicine. With the former he 

 had visited Spitzbergen in 1838 and 1839, and had sojourned on the 

 Faulhorn, in 1841, for eighteen days, at the height of 2,680 metres 

 above the level of the sea. Minute details are given of the prepara- 

 tions made and of the various phenomena observed. The following 

 are the plants noticed on the Grands Mulets : — Draba fladnizensis, 

 Wulf. ; D. frigida, Gaud ; Cardamine bellidifolia, L. ; C. resedifolia, 

 Saut. ; Silene acaulis, L. ; Potentilla frigida, Vill. ; Phyteuma hemi- 

 sphericum, L. ; Pyre thrum alpinum, Willd ; Erigeron uniflorus, L. 

 Saxifraga bryoides, L. ; S. groenlandica, L. ; S. muscoides, Auct. ; S 

 oppositifolia, L. ; Androsace helvetica, Gaud ; A. pubescens, DC. 

 Gentiana verna, L. ; Luzula spicata, DC. ; Festuca Halleri, Vill 

 Poa laxa, Hsencke ; P. caesia, Sm. ; P. alpina var. vivipara, L. 

 Trisetum subspicatum, Pal. Beauv ; Agrestis rupestris, All. ; Carex 

 nigra, AIL 



M. Martins gives interesting details of the adventures which he 

 and his friends encountered, and of their scientific researches into the 

 oscillations of the barometer and of the thermometer, the relative 

 humidity of the air at different hours of the day, the temperature of 

 the soil at different depths, the nocturnal radiation of the surface of 

 the snow, the plants and animals observed, the measuring of the 

 proper heat of the sun's rays, the phenomena of glaciers and the 

 physiological effects manifested in the human body. The work is one 

 of much interest, and will fully repay an attentive perusal.
