I02 NOTES OF A BOTANIST 
ment. Its phrases " were short, but each in- 
cluded all the notes of the diapason ; and after 
repeating one phrase perhaps twenty times, it 
would suddenly pass to another — sometimes with 
a change of key to the major fifth — and continue it 
for an equal space. Usually, however, there was 
a brief pause before a change of theme. I had 
listened for some time before I bethought me of 
writing down its song. The following phrase is 
the one that oftenest recurred : — 
etc. 
Simple as this music was, its coming from an 
unseen musician in the depths of that wild wood 
gave it a weird -like character, and it held me 
spellbound for near an hour, when it suddenly 
broke off, to be taken up again at so great a dis- 
tance that it reached my ear as no more than a 
faint tinkling. 
The only other animal that took my attention 
was a beautiful frog, frequenting moist shady rocks 
and the roots of trees. The belly and legs were of 
the deepest indigo blue ; the back blackish, with a 
green band on each side, beginning at the nose 
and running the whole length of the body ; and 
the toes were papillate. 
Except on the day of our excursion towards 
Carnau, we scarcely ever saw the sun. Thermo- 
metrical observations made at midnight and day- 
break gave every day the same results, viz. — 
Temperature of air at o a.m., 75°. 
5 A.M., 75°. 
6 A.M., 73°. 
„ of water at 6 a.m., 83^°.
