Variation  of  Daily  Means. 
Comparing  all  these  determinations  together  for  results,  and  begimiing  with  the  baro- 
meter, we  find  the  variations  at  the  sea-level  to  be  somewhat  greater  than  those  on  the 
mountain,  and  singularly  inconsistent  with  them,  except  on  one  or  two  occasions,  as  the 
September  storm  at  Alta  Vista. 
On  the  other  hand,  the  variations  of  the  thermometer  are  much  greater  on  the  moun- 
tain than  at  the  sea-level,  having  amounted  on  Guajara  to  9°’7  against  4°‘5  at  the  sea- 
level,  and  on  AltaVista  to  19°-7  against  6°’2  at  the  lower  level  for  the  same  period.
