water,  soluble  in  three  parts  alcohol  and  ether,  from  which  it  is 
obtained  in  crystals. 
From  all  appearances  this  product  is  similar  to  that  obtained 
by  the  action  of  hydrochloric  acid  gas  on  oil  of  turpentine. 
In  preparing  the  crystalline  combination  of  hydrochloric  acid 
gas,  with  wormseed  oil,  the  part  which  still  remained  liquid  was 
mixed  with  water  and  allowed  to  stand  for  some  days.  On  ex- 
amining it  at  the  end  of  this  time,  quite  a  number  of  crystals 
were  found.  These,  on  being  decomposed  by  sulphuric  acid,  gave 
the  peculiar  odor  of  hyacinth,  a  fact  which  seems  to  hint  at  a 
strong  analogy  between  this  composition  and  that  compound  of 
turpentine  oil  and  water  mentioned  by  Deville  and  others,  which 
gives  the  same  peculiar  reaction. 
In  order  to  examine  the  products  of  the  latter  periods  of  the 
first  and  original  distillation,  the  last  two  portions  collected  at 
this  period  were  also  redistilled,  and  the  product  of  redistillation 
freed  from  water,  by  digesting  with  fresh  prepared  chloride  of 
calcium,  as  above.  As  obtained  by  this  process,  the  oil  had  a 
yellowish  brown  color,  a  specific  gravity  by  16°  Cent,  of  ==  0-987 
and  a  boiling  point  at  245°  Cent. 
The  analysis  of  this  oil  gave  the  following  results :

*  It  must  be  mentioned,  that  Mr.  Langerfeld  had  commenced  in  the  Got- 
tingen  laboratory  an  examination  of  the  oil  of  wormseed.  Owing  to  circum- 
stances the  investigations  were  not  finished;  his  analyses  were  kindly 
presented  to  me  by  Prof.  Wohler,  and  correspond  to  some  extent  with  my 
results.
