i* -A-S lam at present uncertain whether the particulars of the 

 northern part of the grand arc have been communicated to the public, I 

 will here subjoin the former conclusions, and combine what was before 

 done with what appears in the preceding paper, in order to inform those 

 readers who are interested in speculations of this nature, that I have not 

 been remiss in promoting objects of general science, while occupied in 

 the more humble task of correcting the erroneous and imperfect geo- 

 graphy of the southern part of the Peninsula. Being in possession of 

 the best English instruments, and traversing from sea to sea, through six 

 degrees of latitude, I have always considered the measurement of a me- 

 ridian arc a necessary part of the general work, as well as an acceptable 

 offering to the mathematician and astronomer ; especially at a time when 

 similar performances have been carrying on in France and England, and 

 at the polar circle. I regret that the whole detailed account cannot now 

 appear under one view, as it would swell a volume to too great a size, or 

 preclude more valuable matter from being admitted. I shall therefore 

 confine myself to the simple results, and combine them with those given 

 in the preceding memoir,.
