 351-b. Written statement to be furnished; presumption. Every person,
  firm,  association,  copartnership  or  corporation  shall  furnish upon
  written demand to any customer, or principal for whom  such  person  has
  executed an order for the actual purchase or sale of any such securities
  or  commodities,  either  for  immediate  or  future delivery, a written
  statement containing the names of the persons from  whom  such  property
  was  bought,  or  to whom it has been sold, as the case may be, the time
  when, place where, the amount of and the price at  which  the  same  was
  either   bought   or  sold;  and  if  such  person,  firm,  association,
  copartnership or corporation shall refuse or  neglect  to  furnish  such
  statement within forty-eight hours after such demand, such refusal shall
  be prima facie evidence that such purchase or sale was made in violation
  of this article.
