1^0 observations of temperature were made by Lieutenant Robinson, 

 whose meteorological observations were intended to assist the corre- 

 sponding Tidal Observations ; and for this reason the wind and barome- 

 ter were observed, not at fixed hours of the day, but at the times of 

 high and low water. 



The following mean temperatures of Port Leopold, observed during 

 the same winter, are recorded by Professor Dove in his Klimatolo- 

 gische Beitrage," 1857 — 



Mean Monthly Temperature of Port Leopold in 1848-9, in degrees 

 Fahrenheit.

I have arranged the observations in two Tables : — 

 Table 1. contains the observations in the order of their occurrence. 

 • Table II. contains the direction and force of the wind for each 



month, arranged with reference to the points of the compass ; and 



The diagrams at the end exhibit the curves of frequency and force 



of wind, constructed from Table II.
