Mr.  de  luc  on 
S32 
I will  only  put  the  fame  cafes  I have  explained  before 
for  fpirituous  liquors : the  fir  ft,  in  which  the  actual  trial 
has  been  made  at  8o°  of  the  Thermometer,  the  fecond, 
in  which  it  is  fuppofed  to  be  made  at  20°,  both  com- 
pared with  o ; and  the  third,  in  which  the  trial  is  made 
at  50  and  1 50.  The  deviations  of  the  three  cafes  between 
the  temperatures  of  o and  20°  (reputed  to  be  the  limits 
of  the  common  obfervations)  are  as  follow : 
1 ft  cafe. 
Je  poferai  {implement  les  memes  cas  que  j’ai  expliques  ci-devant  pour  les 
liqueurs  fpiritueufes ; le  premier  ou  Tepreuve  aftuelle  a ete  faite  a 8o°  du  Ther- 
mometre -3  le  fecond  ou  elk  eft  cenfee  faite  a 20°;  Tun  et  l’autre  comparative- 
ment  a o:  et  le  troifieme  ou  cette  epreuve  eft  faite  a 50  et  a 150.  Les  ecarts  des 
trois  cas,  3 entre  les  temperatures  de  o et  20°,  cenfees  etre  les  limites  des 
obfervations  oidinaires,  font  commefuit. 
V cas.
