A  gallon  of  alcohol  may  be  recovered  from  weak  percolate  easily  in 
forty  minutes. 
The  still  may  be  placed  in  any  suitable  vessel  containing  water 
employed  in  the  laboratory  where  a  water  bath  is  to  be  used — or  for 
small  operations — the  smaller  dish  accompanying  the  still  may  be  placed 
between  the  two  brass  rings,  and  by  disconnecting  the  rubber  tubing  at 
the  top  of  the  glass  gauge-tube  on  the  side,  so  as  to  permit  the  steam 
from  the  water  bath  to  escape,  distillation  at  low  temperatures  may  be 
accomplished,  and  it  is  hardly  necessary  to  add  that  the  still  body,  with 
the  shallow  dish  so  arranged,  may  be  used  as  an  evaporator  when  dis- 
tillation is  not  desired.

NOTE  ON  MINIM  PIPETTES. 
By  Charles  W.  Drew,  Ph.B. 
I  notice  in  the  last  number  of  the  "  Journal"  a  paper  from  the  pen 
of  Dr.  E.  R.  Squibb,  in  which  he  pointedly  assails  my  right  to  describe 
the  device  which  was  figured  and  described  by  me  in  the  March  num- 
ber of  the  "Journal,"  and  within  which  he  asserts  that  "these  pipettes 
and  the  arrangement  figured  are  by  no  means  new  or  original  "  with 
me. 
That  the  pipette  was  originated  by  me  I  never  had  any  intention  or 
desire  to  claim,  and  do  not  by  any  means  claim  in  the  paper  to  which 
he  refers.  Neither  do  I,  nor  did  I,  claim  that  I  was  the  first  to  apply 
the  principle  of  the  syringe  to  any  device  for  obviating  the  necessity  of 
direct  suction  in  their  use.  The  use  of  the  rubber  nipple  for  filling 
the  small  minim  pipettes  and  for  facilitating  its  use  as  a  dropper,  I  have 
been  familiar  with  for  some  time — ever  since  it  was  brought  to  the 
notice  of  the  Philadelphia  College  of  Pharmacy  by  Dr.  Squibb  and 
Prof.  Remington  as  described  in  this  journal  for  1878,  p.  314.  The 
device  figured  by  me  differs  considerably,  not  in  principle,  but  in  con- 
struction and  facility  of  adaptation  to  various  sizes  of  pipettes,  from 
that  of  the  rubber  nipple  ;  and  hence,  I  hold,  is  entitled  to  a  separate 
description,  and  not  at  all  included  in  the  modification  of  Dr.  Squibb. 
The  device  figured  by  me  I  first  made  for  my  own  convenience  while 
assistant  to  Dr.  Squibb,  and  it  had  been  in  use  by  me  for  some  little  time 
before  I  drew  the  attention  of  Dr.  Squibb  to  the  modification,  which  I
