ยง 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.
