Chriftmas, they reckon their winter. During 

 this winter, the Swedifh thermometer of Pro- 

 fefibr Gelfms, was within doors confbantly, be- 

 tween twenty-fix and thirty degrees, and in fu ai- 

 mer between thirty and thirty-three. Out of doors 

 the heat is, between nine #nd five o'clock, ex-

 whole animal and vegetable creation, did not at 

 the fame time a conftant eaft wind and rain, 

 contribute towards abating the heat while the 

 fun is in the zenith. 



Here Loefling found a new world, every plant 

 he beheld was new, and their great number 

 gave him employment from morning to night. 

 This expedition was intended to go up the great 

 Orenoco river, then by Rio Negro, into the Ma- 

 rannon, or river of Amazons, and afterwards 

 along the limits of Brazils, till to thofe pre- 

 tended lakes which are fituated at the fource 

 of Rio de la Plata, which river they intended 

 to follow to Buenos Ayres, and from thence the 

 tour mould go back through Chili, Peru, Lima^ 

 and Quito, all countries which never had been 

 vifited by any botanift of note, if we except 

 that Mr. Juffieu had feen part of Peru.
