and  in  all  stages  of  development,  being  revealed  to  the  view.  A 
careful  calculation,  based  on  a  mounted  section,  would  estimate 
the  number  of  parasites  to  the  square  inch  of  meat  at  250,000. 
Some  eight  or  ten  days  after  the  meat  was  eaten  a  little  daughter 
of  the  persons  alluded  to  was  attacked  by  symptoms  of  trichino- 
sis, and  it  is  feared  will  not  recover.  In  the  case  of  the  man 
and  wife  they  show  signs  of  improvement.  One  remarkable 
point  in  connection  with  this  case  is  the  rapid  development  of 
the  symptoms  of  trichinosis ;  but  six  or  eight  hours  elapsed  from 
the  ingestion  of  the  parasitical  meat  until  the  disease  exhibited 
itself.  I  shall  make  further  investigations  of  the  meat,  and  any 
new  facts  worthy  of  note,  as  well  as  any  new  developments  in 
the  several  cases  of  trichinosis,  I  will  communicate. 
In  conclusion,  I  will  remark  that  I  have  in  my  possession  a 
quantity  of  the  meat,  rich  in  trichina,  that  I  will  exchange  with 
microscopists  for  other  specimens.

NOTE  ON  COD-LIYER  OIL  AND  OTHER  PRODUCTS  FROM 
PORTSMOUTH,  N.  H. 
By  the  Editor. 
Cod-liver  oil  as  a  remedial  agent  continues  to  retain  its  value 
in  the  opinion  of  the  medical  profession,  and  any  information  in 
regard  to  it  is  interesting  to  pharmaceutists  and  physicians. 
Having  recently  had  occasion  to  converse  with  Mr.  T.  E.  0. 
Marvin,  engaged  in  its  manufacture  under  circumstances  favora- 
ble to  its  careful  production,  we  took  occasion  to  elicit  some  facts, 
and  since  to  obtain  some  of  the  by-products  which  may  become 
useful  in  medicine  and  agriculture,  which  consist  of  the  pulveru- 
lent oily  matter,  constituting  chiefly  the  solid  tissues  of  the  cod- 
iivers,  in  the  form  left  by  the  press,  and  of  the  emulsive  aqueous 
liquid  separated  from  the  same  along  with  the  oil  by  pressure, 
and  which  retains  all  the  matters  soluble  in  water  that  the  livers 
contain. 
The  first  condition  necessary  to  the  production  of  cod-liver  oil 
in  its  unaltered  condition  is  a  sufficient  supply  of  the  livers  in  a 
fresh  state.    The  position  of  the  harbor  of  Portsmouth,  N.  H.,
