This list is based on Margaret Conger's Combined Chronology for Use with the Mahatma & Blavatsky Letters to A. P. Sinnett (TUP, 1973), and compared with the Linton-Hanson Readers' Guide to the Mahatma Letters (TPH, 1988) and other chronologies. The sequence has been corrected where warranted, with the understanding that any chronology will be imperfect as most of the Letters were not dated by their authors or by Mr. Sinnett, who sometimes gave incorrect dates received. Recipient is A. P. Sinnett unless otherwise noted.
