near equator from 5"^ S. to 10° N. Perhaps the greater heat 
between and 80° of S. Lat. might be a remnant of the 
southern summer. But the considerable increase of tempera- 
ture in the zone, between 15° and 30° N. Lat. is still more re- 
markable. For though, towards the end of May, the sun 
was near the zenith of those parts, yet this influence, which 
could be only commencing here, must have shown itself in the 
waters near the equator, which the sun had just traversed 
at the time of those observations (in April), which was by no 
means the case. The temperatures at the surface indicate in- 
deed this influence of the sun, being the highest at the equator 
(22|° B.), while the southern half of the tropical seas had al- 
ready assumed an autumnal temperature, since we observe here, 
in 17° S., the same v/armth (18 J° K.) as in 30° N. 
Art. XXIX. — Accowit of the Ohservedions made at Liverpool 
on the Solar Eclipse of September 7. 1820. By Thomas 
Stewart Traill, M. D. F. R. S. E. &c. &c. Communi- 
cated by the Author. 
The following instruments were placed in the garden of my 
house, for the purpose of observation : 
A grand Herschel 7 feet reflecting telescope. 
A Ramsden achromatic telescope. 
A small reflecting telescope by D. Adams, 1| feet. 
A new barometer by Bate, with adjustments for level, and 
rack-work nonius, &c. It was hung in a sheltered place, front- 
ing the north, so that its thermometer gave the indications of 
theTemperature in the shade; but the wind was not sweeping it 
very freely. 
A Leslie’s photometer. 
Rutherford’s register thermometer for both extremes. 
Another register for lowest depression, hung fronting west, 
but screened. It was always 1° or 1|° higher than thaL attach- 
ed to the barometer, and was not noted, being only compared 
occasionally.
