maltose  for  lactose  has  been  of  much  benefit  in  assisting  assimilation 
of  the  carbohydrate,  and  in  increasing  the  weight  of  the  baby,  the 
carbohydrate  percentage  varying  between  five  and  seven  in  these 
cases. 
In  another  series  in  which  a  normal  carbohydrate  percentage  (6) 
has  resulted  in  sugar-indigestion,  with  fermentation  and  diarrhoea, 
we  have  found  that  with  the  same  percentage  of  dextri-maltose,  the 
majority  of  the  cases  clear  up  rapidly,  even  those  in  which  the  lactose 
had  been  first  reduced  to  three  or  four  per  cent,  and  gradually  in- 
creased, but  with  the  symptoms  of  indigestion  persisting.  In  cases 
of  simple  diarrhoea  in  infancy  the  malt-sugar  has  a  much  more 
beneficial  effect  than  milk-sugar,  and  it  can  certainly  be  borne  in 
higher  percentages.  In  the  majority  of  cases  malt-sugar  appears  to 
be  slightly  constipating:  but  it  is  of  interest  to  note  that  in  a  few 
cases  of  malnutrition,  in  which  the  bowels  have  been  constipated  and 
movements  have  been  secured  only  by  the  employment  of  enemata 
or  by  mechanical  means,  after  a  few  days  of  the  use  of  dextri- 
maltose  in  the  feeding,  the  proportion  of  fat  and  proteid  remaining 
the  same,  but  the  sugar  being  increased  to  six  or  seven  per  cent.,  the 
stools  become  less  hard  and  of  a  better  consistency.  This  is  true, 
however,  only  of  certain  cases,  for  in  that  of  other  infants  with 
constipation  the  stools  have  become  slightly  more  constipated. 
It  would  seem,  therefore,  that  malt-sugar  has  marked  advantage 
over  either  milk-sugar  or  cane-sugar  in  the  feeding  of  infants  unable 
to  assimilate  or  thoroughly  digest  the  milk-sugar  or  cane-sugar,  and 
in  the  feeding  of  infants  suffering  from  diarrhoea.

The  employment  of  inhalations,  in  the  treatment  of  pathological 
conditions  of  the  respirator}-  tract,  has  appealed  to  many  as  a 
rational  therapeutic  procedure,  and  medical  literature  is  replete  with 
descriptions  of  generators,  vaporizers,  and  pneumatic  cabinets,  to- 
gether with  the  various  substances  thought  to  possess  remedial 
properties,  which  have  been  employed.    A  review  of  this  literature
