acid  was  obtained,  which,  combined  with  potassa  and  treated  with 
sulphuric  acid  and  alcohol,  had  the  smell  of  butyric  ether.  The 
quantity,  however,  was  too  small  for  making  a  butyrate  sufficient 
for  analysis ;  only  butyrate  of  oxide  of  ethyle,  with  its  charac- 
teristic properties,  was  obtained. 
The  remaining  acid  liquid  left  a  mass  on  evaporation,  which, 
on  dissolving  in  a  little  water  and  evaporating,  gave  crystals  of 
succinic  acid,  the  silver  salt  of  which  was  made  and  analysed. 
The  author  comes  to  the  conclusion,  that  paraffin  is  a  derivate 
of  fat  bodies,  formed  by  a  process  of  reduction. — J.  M.  M.

On  the  Inhalation  of  Sulphur et  of  Carbon  in  Caoutchouc  Fac- 
tories. 
In  the  Paris  Academie  de  Medecine,  Delpeeh  read,  on  January 
15th,  a  notice  on  the  diseases  to  which  workingmen  in  caout- 
chouc factories  are  subject,  and  which  have  not  yet  been  des- 
cribed. From  his  observations  Delpeeh  comes  to  the  following 
conclusions : 
1.  That  those  workingmen  are  subject  to  severe  indispositions, 
consisting  of — 
a.  Disturbance  in  digestion ;  anorexia,  nausea,  vomiting, 
diarrhoea,  constipation. 
b.  Disorders  of  intelligence ;  stupidity,  loss  of  memory,  ex- 
traordinary irritability,  unaccountable  passion. 
c.  Severe  disorders  in  the  functions  of  the  nervous  system  ; 
headache,  vertigo,  disturbances  in  seeing  and  hearing,  impotency, 
palsy,  especially  that  of  motion. 
2.  That  the  observance  of  the  above  disorders,  together  with 
the  experiments  on  animals,  permit  of  the  inference,  that  they 
are  caused  by  the  inhalation  of  sulphuret  of  carbon. 
3.  That  the  proper  remedies  ought  to  be  searched  for  to  pre- 
vent these  maladies. — Gaz.  Med.  de  Paris,  1855,  No,  3.
