Character  of  the  Urine.

seem  to  take  place,  which  forms  a  distinguishing  feature  from 
diabetic  urine. 
In  the  pale  urine  of  a  delirium  tremens  case,  to  which  chloral  was  ad- 
ministered in  large  doses,  the  amount  of  Fehling's  solution  reduced 
by  the  eliminated  urine  corresponded  to  0-4  per  cent,  of  glucose. 
In  the  light-colored  specimen,  with  the  specific  gravity  of  1-022, 
of  a  patient  who  had  taken  60  grains  of  the  drug,  administered 
within  two  days,  the  amount  of  reduction  corresponded  to  about  015 
per  cent. 
This  case  was  kept  under  observation,  the  urine  being  examined 
before  and  after  the  ingestion  of  chloral. 
The  reduction  took  place  only  during  the  administration  of  the 
drug. 
A  singular  fact  is  that  in  chloral  urine  the  Braun-Johnson  picric 
acid  and  potash  test  do  not  react.  This,  together  with  the  non- 
action of  the  bismuth  test,  is  remarkable. 
Croton  Chloral  Urine. — Regarding  butyl  chloral  urine,  conflicting 
statements  are  found. 
According  to  some  writers,  it  will  reduce  Fehling's  solution,  while 
according  to  Neubauer  and  Vogel,  butylchloralic  acid,  under  which 
form  the  drug  is  eliminated,  possesses  no  reducing  action  upon 
cupric  or  other  metallic  oxides  in  alkaline  solutions. 
In  one  sample  examined  by  the  writer,  the  reducing  action  found 
was  slight,  by  no  means  as  prominent  as  in  the  case  of  chloral  urine. 
Chloroform  Urine.— -In  connection  with  chloral  urine,  it  may  inci- 
dentally be  mentioned  that  urine  containing  chloroform  will  also 
reduce  Fehling's  solution. 
The  distillate  from  a  specimen  of  this  kind  reduces  ammoniacal 
silver  nitrate  solution,  while  in  the  distillate  from  urine  containing 
acetone,  no  such  action  takes  place  with  either  reagent. 
Turpentine  Urine. — The  urine  voided  after  the  administration  of 
oil  of  turpentine  has  repeatedly  been  the  subject  of  investigation. 
The  peculiar  odor  communicated  to  the  secretion  by  this  drug  has 
been  described  as  resembling  that  of  violets,  although  the  original 
terebinthinate  odor  is  frequently  noticeable,  especially  upon  the 
addition  of  mineral  acids. 
In  examining  turpentine  urine  for  abnormal  ingredients,  a  knowl- 
edge of  the  physiological  action  of  the  oil  is  important. 
Albumin  Reactions. — Turpentine  urine  is  not  infrequently  found 
to  respond  readily  to  albumin  tests.
