An  examination  of  an  original  bottle  showed  it  to  be  a  colorless, 
syrupy  liquid  of  a  neutral  reaction,  specific  gravity  1.2177  at  150. 
A  qualitative  analysis  showed  the  presence  of  glycerin,  mercury, 
sodium,  and  chlorine.  Further  quantitative  determinations  showed 
that  in  100  c.c.  of  the  liquid  there  were  present  0.4944  per  cent, 
of  mercuric  chloride  and  0.9269  per  cent,  of  sodium  chloride. 
It  is  conclusively  proven  by  Zernik  that  mergandol  is  a  solution  of 
these  two  salts  in  glycerin  and  water  and  not  a  solution  of  quick- 
silver-natrium-glycerates  in  glycerin. 
Phagocytin. — Under  this  name  there  has  appeared  on  the  German 
market  a  sterile  solution,  recommended  by  the  exploiters  for  sub- 
cutaneous injection  in  septic  and  exhausting  diseases.  It  is  dis- 
pensed in  ampouls  each  containing,  so  the  label  stated,  one  cubic 
centimetre  of  a  5  per  cent,  solution  of,  what  the  makers  claim, 
sodium  nucleinate. 
At  the  request  of  the  Deutschen  Apothekervereins  the  Pharma- 
ceutic Institute  undertook  an  investigation  of  this  preparation. 
It  was  marketed  in  cartons  of  twenty  ampouls  each.  The 
ampouls  contained  a  brownish  liquid  of  an  alkaline  reaction;  upon 
t^e  addition  of  a  mineral  acid  a  white,  flocculent  precipitate  was 
formed. 
Each  pmpoul  contained  somewhat  more  liquid  than  the  quantity 
stated  on  the  label. 
Unon  evaporation  of  one  eubi"  centimetre  of  the  liquid  there 
remained  a  brown,  amorphous  residue  which,  after  drying  at  ioo°, 
weighed  0.0^4  gramme,  somewhat  more  than  stated  on  the  label. 
On  heating  the  residue  to  ash  there  developed  the  characteristic 
odor  of  garlic,  which  led  the  analvst  to  suspect  the  presence  of 
prcenio;  this  suspicion  w^s  hter  confirmed  by  positive  results  with 
MarcIV^  an"1  Pettcndorf's  tests. 
Tn  the  oriemal  solution  the  presence  of  arsenic  could  not  be 
demonstrated  in  the  usual  manner.  Only  after  destruction  of  the 
organic  substance  was  its  presence  confirmed  by  the  above  tests;  it 
was  also  precipitated  as  sulphide  with  hydrogen  sulphide. 
The  ash  of  phagocytin  showed  further  the  presence  of  sodium, 
besides  traces  of  potassium  and  iron,  combined  with  carbonic,  phos- 
phoric, and  sulphuric  acid. 
Further  Quantitative  determinations  showed  that  phaeocytin  was 
a  c  ner  cent,  solution  of  an  organic  combination  of  arsenic. 
Plejapyrin. — The  introducers  of  this  remedy  speak  of  it  as  being
