Mean latitude deduced from the above obfervations 41" 59' 52".7 



By which it appears that we were too far fouth by 7.3 



The correftion being made, the guide line was correfted 

 back to the Delaware, and another guide line carried on weft 

 191 miles from the correfted point north of our obfervatory, 

 at the termination of which the following zenith diftances were 

 obferved.

* At this ftation a number of obfervations were rejeiSted, on account of their difagree- 

 ment, which we fortunately difcovered was owing to the atmofphere being affeifted by 

 the numerous fires we kept up to keep off the flies, rauiketoes, and gnats, which are very 

 Itroublefome in that part of the country.
