 the duplicates at Marseilles, with the intention 

 of ordering them to be sent to Tunis or Algiers, 

 when I should find an opportunity of passing 

 over to the coasts of Barbary. In peaceable times 

 travellers ought by no means to carry with them 

 the complete collection of their instruments : 

 they should on the contrary cause them to be sent 

 successively, in order to replace such as suffer 

 most by use and carriage. This precaution is 

 particularly necessary, when they are obliged to 

 determine a great number of points by means 

 merely chronometrical. But in times of maritime 

 warfare, it is highly prudent never to lose sight 

 either of instruments, manuscripts, or collec- 

 tions. Sad experience, as I have observed in the 

 introduction to this work, has confirmed the 

 justness of this observation. Our abode at Ma-
