In lieu of taking the thermometric means from Dr. Wrytin’s 
Tables, which are only entered for the hours at which the barometer 
was registered, the following extracts from a Journal kept by Captain 
Luoyp, for which also we are indebted to Dr. Wrtiz, will better 
serve to furnish the range of the daily temperature.
