that could be desired, because it sometimes happened that observations which fall in the 

 two divisions were made only a few miles apart, for example when two pai-ties weie near 

 to One Ton Camp, one to the north, and the other to the south ; while at other times 

 the whole expanse of the Barrier separated the parties taking the observations. Still this

The mean daily temperatures for the Barrier have been obtained from the ob.servations
