Spermaceti.

Heintz,12  in  his  classic  communications,  reports  a  cetine  which 
he  obtained  by  repeated  recrystallizations  that  melted  as  high  as 
55-5°  C. 
After  eliminating  the  extremely  high  specific  gravity,  0-96,  and 
the  high  fusing  points,  49  and  500  C,  which  probably  represent 
cetine,  there  are  left  the  following  recorded  constants :  spermaceti, 
melting  from  416  to  47  7°  C,  and  specific  gravity,  approximating 
0943  at  1 50  C;  cetine  fusing  from  48  9  to  55-5°  C. 
To  what  extent  the  above  constants  agree  with  those  obtained  in 
the  course  of  this  investigation,  the  following  table  will  show :

No.  1  was  obtained  from  Prof.  Trimble,  being  a  sample  of  the 
specimen  in  the  Museum.  It  was  obtained  from  New  Bedford,  and 
placed  in  the  Museum  of  this  College  in  1877.  The  extremely  high 
acid  number  indicates  old  age.  No.  2  was  furnished  by  Prof.  Stev- 
ens, of  the  University  of  Michigan ;  he  did  not  vouch  for  its  purity. 
No.  3  was  kindly  sent  by  Mr.  England.  It  was  represented  to  him 
to  be  pure,  and  it  was  a  very  nice  article.  Nos.  4  to  17,  inclusive, 
represent  data  obtained  from  samples  taken  from  90  cases,  repre- 
senting about  4,700  pounds  of  spermaceti.    All  this  was  procured
