On  continuing  to  raise  the  temperature,  at  a  little  over  100°  C,  crys- 
tals of  various  shapes  were  deposited  ;  these  again  disappeared  at  160^ 
C.  to  180°  C,  but  were  again  thrown  down  at  200°  C.  and  upwards. 
Lead  sulphate  was  soluble  to  the  extent  of  1*5  parts  in  100  of  boiling 
acid.  When  cold  a  few  crystals  were  deposited,  and  1*15  parts  retained 
in  solution. — Chem.  News  \_Lond.~\^  June  4,  1875. 
VARIETIES. 
Liquor-selling  by  Apothecaries. — The  "Boston  Medical  and  Surgical  Jour- 
nal "  for  July  15th,  reminds  the  physicians  of  Massachusetts  that,  according  to  the 
new  license  law  now  so  energetically  carried  out  in  that  State,  apothecaries  are  not 
allowed  to  sell  liquors,  except  alcohol,  for  any  purpose,  without  an  order  from  a 
physician,  "  between  the  hours  of  twelve  at  night  and  six  in  the  morning,  or  on  any 
part  of  the  Lord's  day."  If  this  is  remembered  a  great  deal  of  trouble  will  be  saved. 
Ever}'  apothecary,  who  has  a  license,  is  under  bonds  of  one  thousand  dollars  to  obey 
the  law. 
Anesthetic  Action  of  Bromoform. — Dr.  Rabuteau  reported  to  the  Biolog- 
ical Society  of  Paris  some  cases,  showing  that  the  application  of  bromoform  to  the  skin 
produced  anaesthesia  without  the  revulsive  and  painful  effects  of  the  application  of 
chloroform. — Amer.  Journ.  Med.  Sciences^  July,  from  Gaz.  Hebd.  de  Med.  et  de  Chir  ,

Poisoning  by  Rhus  Toxicodendron. — Dr.  S.  W.  Morrison  uses  a  solution  of 
carbolic  acid,  ^ss.  and  sulphite  of  sodium  ^iii  in  six  ounces  of  water,  to  be  applied 
to  the  parts  affected  on  bandages  of  muslin  j  the  inflammation  is  thereby  checked 
and  relief  afforded  immediately. — Philada.  Med.  Times,  July  3d. 
New  Sources  of  India  Rubber. — It  is  well  known  that  rubber  abounds  in  the 
milky  juices  of  many  plants  besides  the  caoutchouc-tree  ;  for  example,  lettuce  and 
dandelion.  A  company  has  been  formed  in  London,  Ontario  Province,  for  the 
extraction  of  caoutchouc  from  milk-weed  [Euphorbia  corollata),  the  juice  of  which 
contains  some  4  per  cent,  of  rubber.  The  plant  is  partially  decomposed,  steamed, 
then  treated  with  coal-tar  naphtha,  which,  being  distilled,  leaves  the  residuary  caout- 
chouc in  the  solid  form. — Journ.  of  Ap.  Sci.,  July  ist. 
The  Briar  Root  of  Commerce. — Sixty  tons  of  laurel  roots  [Kalmia  latifoliay 
Lin.)  from  the  Rappahannock  were  transferred  to  a  steamer  at  Baltimore,  not  long 
since,  and  consigned  to  Philadelphia,  there  to  be  manufactured  into  pipes.  Many 
of  the  handsome  articles  exposed  in  the  tobacconists'  show-cases  and  windows,  and 
sold  for  briar-root  pipes,  are  made  out  af  this  identical  material,  which  is  purchased 
and  dug  up  at  very  little  expense,  in  all  the  lower  counties  of  Maryland. — Journ.
