to  time  he  describes  tropococain,  holocain,  eucain,  stovain,  alypin 
and  novocain  at  some  length  and  concludes  that  while  it  is  true 
that  these  substances  are  relatively  more  stable  than  cocain,  and  are 
therefore  more  readily  sterilized,  the  numerous  objectionable 
features,  such  as  unreliability,  irritating  properties  and  the  produc- 
tion of  a  hyperemia,  are  so  much  more  objectionable  that  cocaine 
must  be  admitted  to  be  by  far  the  most  satisfactory  as  well  as  the 
safest  local  anesthetic  in  all  varieties  of  eye  work. 
Tannisol  is  a  reddish-brown,  odorless  and  tasteless  powder  that  is 
insoluble  in  water,  ether  or  benzine,  but  is  soluble  in  alcohol  and  in 
dilute  solutions  of  alkalies  or  of  the  alkaline  carbonates.  It  is 
directed  to  be  used  internally  in  cases  of  intestinal  catarrh,  and 
externally  for  a  variety  of  inflammatory  conditions  of  the  skin. 
Internally  it  may  be  given  in  doses  of  0-50  gramme  {Phar.  Centralh., 
1906,  page  1006). 
Theolactin. — This  name  has  been  applied  to  a  double  salt  of  theo- 
bromin  sodium  and  sodium  lactate.  It  occurs  as  a  white  hygro- 
scopic powder,  readily  soluble  in  water  and  having  a  distinctly  bit- 
ter taste.  It  is  said  to  be  an  active  diuretic,  but  is  not  free  from 
occasional  side  effects  in  the  'form  of  gastric  disturbances.  [Phar. 
Zeit.,  1907,  page  49.) 
Tinctura  oka  Europe ae, — A  tincture  made  with  60  per  cent,  alco- 
hol from  the  dried  leaves  of  the  European  olive  has  been  used  as  a 
febrifuge  as  well  as  a  general  tonic  in  place  of  the  tincture  of  cin- 
chona bark. 
Triacetyl  morphin. — This  substance  has  been  isolated  from  a  mix- 
ture of  acetyl  derivatives  of  morphin.  Triacetyl  morphin  melts  at 
from  206  to  2080  C,  is  only  slightly  soluble  in  water  or  cold  alcohol, 
but  is  readily  soluble  in  acids.  With  hydrochloric  acid  it  forms  a 
salt  that  crystallizes  in  the  form  of  long  needles.    {Phar.  Centralh., 
1906,  page  928.) 
Tulaselactin  is  the  name  given  by  Behring  to  a  substance  that  is 
expected  to  immunize  infants  against  tuberculosis.    {Phar.  Centralh., 
1907,  page  24.) 
Tulase  {A.  jf.  P.,  1906,  page  582)  is  the  name  given  by  Behring 
to  his  immunizing  and  curative  serum  for  tuberculosis. 
This  preparation  is  said  to  contain  all  of  the  constituents  of  the 
Koch  bacillus.  It  occurs  as  a  clear  fluid  which  has  the  general  out- 
ward characteristics  of  thin  honey.    It  may  be  given  subcutaneously,
