"Our Opium Market has fluctuated very little since the date of last advices, the 28th ultimo, particularly at Whampoa; while along the Coast prices have been better maintained, but the deliveries have been on a reduced scale. In Macao Malwa fell to 345 dollars per chest, and several hundreds of chests were sent out to Lintin, when the prices, of all kinds, improved a little."
William Jardine in Canton to Jamsetjee Jejeebhoy in Bombay, 13 March 1838.*
