varied, and were very easily excited — mine fluctuated from 

 80 to 120 beats." 



" December 28th. This has been a pleasant day for these 

 regions. At sunrise the effect of horizontal refraction on the 

 sun was very perceptible. It seemed quite small as it ap- 

 peared above the sea, forming a long horizontal ellipse of two 

 and a half diameters, first enlarging on one side and then 

 another." 



" On the 31st the temperature at noon in the sun was 92°, 

 in the shade at 55°, and after dusk it was as low as 13°. In 

 the afternoon I had an attack of the Mountain Sickness. I 

 was sick at the stomach, and had a severe pain in the head." 



" The night was favorable for observations, and we made 

 many." 



On the morning of the 5th of February we got under-way, 

 and shaped our course for Maui. 



The following day, at 2.45 P. M., the Island of Kaloolawe 

 bore west north-west. This is a small, barren island, and 

 used by the Hawaiian Government as a place of exile for con- 

 victs, who depend on rain-water for drink, and glean a scanty 

 subsistence from potatoes, which they manage to raise on one 

 or two fertile patches. At 4 P. M. we descried the Island of 

 Maui ; it appeared at a distance like two distinct islands. 

 The coast was generally bold and steep, and intersected by 

 numerous valleys, or ravines. Many of these are apparently 

 formed by streams from the mountains which flow through 

 them into the sea. The rocks along the coast were composed 

 of very hard compact lava, or a kind of basalt' 



The habitations of the natives appeared in clusters at the 

 openings of the valleys, or scattered over the sides of the 

 hills. It is a beautiful island. 



About sunset we came-to off Lahaina, the principal town.
