pandanus forests are in full bloom, the whole air for miles around is 

 scented with the fragrance. 



This day, for the first time, I saw a deranged native. He had 

 escaped from his keepers ; and I thought he was rather harshly used 

 in what I saw of the aifray. There was great difficulty in securing 

 him. 



Within a mile or two of the observatory, we met Mr. Drayton, 

 o^oingf out on another excursion. 



We reached the observatory after an absence of forty-two days, 

 and it was delightful to feel ourselves as it were at home again, after 

 so arduous and fatiguing an expedition. I had the pleasure to hear 

 that every thing had arrived safely, and that all were well. On 

 inquiry being made for the Kanaka that had been missing, I learned 

 that a party of natives had gone to the mountain in search of him, 

 but that little hope was entertained that he would be found. 



On the 24th, Lietitenant Carr, Dr. Fox, Lieutenant Case, and 

 several of the other officers, were allowed permission to visit the 

 crater. 



On the 25th, 26th, and 27th, we were employed in putting up the 

 pendulum apparatus, and began on the night of the latter to observe 

 coincidences. The three series obtained, to my great astonishment, 

 did not agree. I could not account for the discrepancies, for I exa- 

 mined the whole apparatus, agate planes, knife, edge, &c., and found 

 them in perfect adjustment both with plumb-line and level ; the scale 

 and telescope were also found correct; the rate of the clock was steady 

 under hourly comparisons with the siderial clock, and observations 

 of the transits of stars. 



Although I had covered the pendulum-house with its tent, I 

 thought that some of the discrepancies occurring might be owing to 

 its want of uniformity of temperature. I therefore, on the 29th, had 

 a grass-house built over both, which remedied any defect of tempe- 

 rature. I then continued to observe, but did not find the results 

 more satisfactory ; I therefore took down the whole apparatus, put 

 it up, readjusted it anew, and took another series during the night. 

 These were rather more in accordance. I continued observing 

 through the 30th and 31st, but with no satisfactory results. I then 

 examined the pendulum again with the plumb-line on both sides at 

 the same time : they both coincided with the marks made in London 

 by Mr. Baily and myself, in 1836. I next tried the iron pendulum,
