Y matched exactly the requested amount. Since B.a. Sterne was requested most frequently, extra vials of secondary stocks were sometimes prepared to fill future requests. Due to the special packaging requirements of temperature sensitive materials, the procedure used to prepare requested materials for shipment was modified.
