cotina,  ononin,  oxycanthin,  papaverina,peucedanin,  picrotoxin,  rhubarbarin, 
rhein,  solania,  theobromin,  carvacrol,  elaterin,  quassin,  sanguinarina,  be- 
beerin,  atropia,  asarone,  anemonin,  sesculin,  aconitia,  caffein,  ergotin, 
conia  (colorless),  indigotin,  nicotin,  xylostin,  jalapin,  hsematoxylin,  glycy- 
rhizin,  gentisin,  filicin,  digitalin,  emetina,  daturia,  delphinia,  colombin, 
colocynthin,  codeia,  chelidonin,  cetrarin,  cantharidin,  brucia,  phloridzin, 
piperin,  urea,  salicin,  mannite,  amygdalin,  aloxan,  quinia,  and  cinchonia  ; 
kinic,  valeranic,  succinic,  uric,  picric,  uvic  (or  paratartaric),  benzoic,  gallic, 
pyrogallic,  hippuric,  kinovic,  meconic,  anemonic,  butyric,  and  malic  acids  ; 
oenanthic,  formic,  acetic,  amylic,  butyric,  valerianic,  and  chloric  ethers;  vo- 
latile oils  of  vitis  vinifera,  salvia,  ruta,  (seed  and  herb,)  rosse  (pure),  milli- 
folium,  melissa,  majoram,  lauro-cerasus,  lauras,  hysoppus,  cuminum,  carda- 
momi,  angelica,  and  numerous  others. 
In  addition  to  these  organic  principles,  a  great  variety  of  rare  and  beau- 
tiful mineral  salts  and  compounds,  all  like  the  preceding,  enclosed  in  glass 
stopped  vials  and  bottles,  and  appropriately  labelled.  As  a  whole,  this  is 
the  most  complete  cabinet  of  the  kind  we  have  ever  met  with. 
The  specimens  of  E.  Merck,  of  Darmstadt,  Hesse-Darmstadt,  are  remark- 
able for  their  rarity,  beauty,  and  purity,  and  being,  as  they  are,  his  own 
manufacture,  they  are  unsurpassed  by  any  similar  deposit  in  the  exhibi- 
tion. They  include  veratria  (in  crystals),  menispermia,  digitalin,  filicin 
inulin, iodoform,  cantharidin,  gentisin, theobromin,  atropia,picrotoxin,brucia? 
asparagin,  amygdalin,  narcein,  papaverina,  ononin,  cubebin,  narcotin,  peu- 
cedanin,  santonin,  phloridzin,  jalapin,  salicin,  cinchonia,  strychnia,  codeia, 
morphia,  caffeine  ;  and  tannic,  hippuric,  gallic,  pyrogallic,  and  kinic  acids. 
These  specimens  are  in  bottles  from  two  ounces  to  sixteen  ounces  capacity, 
and  are  in  most  instances  beautifully  crystallized. 
0.  Herman,  for  the  Royal  Prussian  manufactory,  deposits  the  following 
specimens  in  gallon  bottles  : — pure  carbonate  of  potash,  iron  alum,  nitrates 
of  strontia  and  baryta,  succinic  acid,  gallic  acid,  glacial  phosphoric  acid, 
potassium,  sodium,  caustic  potash,  and  hyposulphite  of  soda.  The  alkaline 
metals  and  the  phosphoric  acid  were  very  fine  specimens,  and  the  whole 
are  of  excellent  quality. 
Dr.  L.  C.  Marquart,  of  Bonn,  exhibits  bromine,  chloroform,  acetic  and 
acetic  amylic  ethers,  oxide  of  uranium,  and  nitrobenzyl,  or  artificial  oil  of 
bitter  almonds. 
Spalm  &  Schimmel,  of  Leipsic,  Saxony,  and  Trepte  &  Ferke  of  the  same 
place,  exhibit  a  variety  of  volatile  oils. 
France, — The  French  manufacturing  chemists  have  not  availed  them- 
selves of  the  exhibition-  to  expose  their  products.  Menier  &  Co.,  of  Paris, 
exhibit  powdered  drugs  and  vegetable  extracts.  Of  the  latter  several  have 
been  prepared  in  vacuo,  and  present  the  form  of  desiccated  frothy  masses 
The  color  indicates  careful  preparation.
