Serpents . — At Colombo, on the 27tli of August, air 81°.5, 
the temperature of an elegant green snake, a species of Coluber, 
was 88°.5, in cesophago. At the same place, on the 24th of 
August, air 82°.5, the temperature of a small species of brown 
snake, another species of Coluber, was 84°.5 in ahdomine. On 
the 23d of September, air 83°, the temperature of different spe-

4 th, Of' the Temperature of ‘ Fishes. 
Shark . — In Lat. N. 8 ° 23', on the 11th of March 1816, air 
71°.75, sea 74°.75, the temperature of a large female shark, just 
taken, and still alive, was 77 ° in the deep muscles near the tail 
Bonito . — In Lat. S. 1° 14', on the 29th of July 1816, air 78°, 
sea 80°.5, the temperature of the heart of this fish, which lies very 
near the surface, was 82° ; and of the deep seated muscles, 99 °« 
These observations were made immediately after the fish was 
taken. I may remark, that the heart and gills of this fish 
were unusually large, and the latter of a dark red colour ; 
farther, that the muscles in general, which were very thick and 
powerful, were red like those of a porpoise, and that the boni- 
to appears to be almost as fond of raising its head above the 
water as the porpoise itself : with these circumstances proba- 
bly its extraordinary temperature is connected. 
Common Trout.— Near Edinburgh, in the spring, river 56°, 
the temperature of this fish was 58°. 
Flying Fish . — In Lat. N. 6 ° 57', on the 12th of March, air 
77 °, sea 77 °. 5, the temperature of this fish, the instant it fell on 
the deck, was 78°. 
5th , Of the Temperature of Mollusca. 
Common Oyster .— On a rock about a quarter of a mile from 
the shore, off Mount Livinia, where the water was about a foot 
deep, in December, the temperature of the common oyster was 
the same as that of the sea, viz. 82°. 
Snail .- — At Kandy, on the 11th of June, the temperature of 
one of a large species of snail that abounds in the woods of Cey- 
lon, was 76°, and that of another 76|°, after having been confined
