XXXII. XXXIII. XXXÍV. XXXV. Signals on 

 Guapub, the mountain of Campanario, and those 

 of Cosin, and Mira. 



The observations to be made at these four stations 

 could not be finished till those alarming reasons which 

 called us to Lima and Chili no longer subsisted, and 

 we were returned to Quito. The work at the first 

 and last stations was dispatched without the necessity 

 of lodging there; for being near Quito and the vil- 

 lage of Mira, when the weather promised us a favour- 

 able opportunity it was only an easy ride ; but we 

 found it very ditFerent with regard to the stations of 

 Campanario and Cosin. However, we left all the four 

 at the same time, namely, on the 23d of May 1744 ; 

 the day when Don George and my^elfput the finish- 

 ing hand to the astronomical observations which we 

 had re-assumed on the J4th of February of the 

 same year ; and thus the whole process relative to 

 the mensuration of an arch of the meridian was con- 

 cluded. 



Signals erected on deserts, ^c. ithere the observations 

 were conducted by Mr. Godin ajid Don George 

 Juan. 



The stations immediately subsequent to the admea- 

 surement of the base of Yaruqui, in the year 1736, 

 and afterwards not made use of, as we have already 

 observed, were common to both companies; the me- 

 thod which was afterwards follovv^ed, for every one to 

 observe two angles in all the triangles, not having 

 been thoue^ht of: thouo;h it both shortened the work, 

 and, at the same time, rendered it much easier : so 

 that Don George Juan and Mr. Godin were ovi the 

 deserts of Yllahalo and Pambamarca, at the same 

 time with Mess.Bouguer and Condamine and myself.
