during  the  process  of  manufacture,  and  that  the  presence  of  ortho- 
phosphate  is  due  to  the  carelessness  of  the  operator  in  the  making 
of  the  pyrophosphate  of  sodium. 
Only  two  of  the  above  samples  claimed  to  be  U.S.P.  on  the  label, 
these  being  Nos.  2  and  6. 
For  examining  iron  phosphate  soluble,  the  directions  should 
read : 
If  1  gramme  of  the  salt  be  boiled  with  10  c.c.  of  potassium  or 
sodium  hydrate,  T.S.,  a  reddish-brown  precipitate  will  be  produced, 
and,  if  the  colorless  filtrate  from  this  precipitate  be  acidulated  with 
hydrochloric  acid,  then  a  slight  excess  of  ammonia  water,  added, 
and  a  solution  of  magnesium  sulphate  (magnesium  sulphate,  10 
grammes;  ammonium  chloride,  20  grammes;  water,  a  sufficient  quan- 
tity to  make  120  c.c.)  added  so  long  as  a  precipitate  is  formed,  this 
precipitate  should  be  completely  soluble  in  acetic  acid,  added  in 
slight  excess,  and  not  reprecipitated  upon  boiling. 
FLORA  FILIPPINENSIS.1 
In  the  Free  Library  of  Philadelphia  (Chestnut,  above  Twelfth),  I 
found  the  celebrated  Flora  Filippinensis,  by  Blanco,  Mercado  and 
Llanos,  edited  by  Naves  and  Villar,  Manila,  1877-1880,  in  two  big 
folios  plates,  and  four  folios  text. 
This  flora  will  be  found  on  the  top  floor,  where  the  other  rare  and 
costly  works  are  kept. 
I  give  in  the  following  a  synopsis  of  contents  (merely  number  of 
species  in  each  family),  which  may  come  handy.  The  plates  are 
fully  the  equal  of  any  I  have  seen  (colored),  but  not  exactly  arranged 
properly,  and  not  provided  with  numbers.

the  editor,  and  it  was  thought  that  it  might  be  useful  to  others.
