Section 46. Information; penalty

The  employee or his dependents, if so
  requested, shall furnish the  last  employer  or  the  board  with  such
  information  as  to  the  names and addresses of all his other employers
  during the said twelve months, as he or they may possess;  and  if  such
  information  is  not furnished, or is not sufficient to enable such last
  employer to take proceedings against  a  prior  employer  under  section
  forty-four,  unless  it  be  established  that  the disease actually was
  contracted while the employee was in his employment, such last  employer
  shall  not be liable to pay compensation, or, if such information is not
  furnished or is not sufficient to enable  such  last  employer  to  take
  proceedings  against other employers under section forty-four, such last
  employer shall be liable only for such part of the total compensation as
  under the particular circumstances the board may deem just; but a  false
  statement in the information furnished as aforesaid shall not impair the
  workman's rights unless the last employer is prejudiced thereby.
