was 78“ while the maximum did uot rise above 82°. During the 
same period the temperature at my house on the savana in 
Port-of-Spain was minimum 70“ maximum 90°. The temperature 
of the surface water of the Gulf was constantly 82’ during the 
time of our stay. We thought we perceived at times the existence 
of a colder underlayer of water, but I was unable to verify the 
act. In October 1881 when we were under quarantine at the 
nve Islands I found the temperature of the Gulf water to be 
84 ' The tem Perature of the Maraval river water at the time 
Pot marl y years I have made occasional observations 
of the temperature of the river water. These observations were 
always taken early in the morning before the water had time to 
ecome heated by the sun’s rays and I never found the tem- 
perature below 7 4° or above 78°. 
These observations would appear to show. 
1“ That the temperature of the air at the Gulf 
Islands does not usually fall so low or rise so 
high as on the main island of Trinidad. 
2“ That the temperature of the sea water is much 
higher than that of the river water. Probably 
the temperature of the Gulf is itself lower than 
t at of the Catibean Sea (which observations 
show to be about 84“ at this time of year) owing 
to the influence of the Orinoco and other rivers 
m pouring a quantity of water of a lower temper- 
ature into the Gulf.
