The barometric readings are those of an uncorrected aneroid. Instrumental error 

 unknown. Elevation of aneroid about 30 feet above sea level. 



The thermometers (centigrade, but here converted to scale of Fahrenheit) were 

 hung in a small perforated wooden box on the south side of the officers' house. In 

 view of the generally overcast sky this circamstance may not have affected the 

 temperature record to any great extent. ^> 



The percentage of cloudiness was obtained from the eye estimates of the observer, 

 recorded on a scale of to 10 at each observation. The mean of the four daily 

 observations was used as the mean for the day; 100 per cent represents sky completely 

 overcast. 



The percentage of relative humidity was obtained from the difference between the 

 dry and wet bulb thermometers. 



" Drizzle " is not recorded as rain. 



Direction of wind is by compass. 



The maximum force of wind here given is the maximum force at the time of the 

 four daily observations. It was obtained from the estimates of the observer, recorded 

 on a scale of to 10, representing calm and 10 hurricane.
