Note 3 — Chapter XXX · THE BURIATS.
Reading edition
The lamas are divided into four classes. Those of the first are occupied with the study of doctrine, and with the tenets and mysteries of their faith; those of the second with the regulation of certain religious rites and ceremonies; those of the third busy themselves in the study and direction of their worship; the fourth class study and practise medicine, in which it would appear that some of them attain eminence, for when we arrived at Kiakhta we found Mr. Tokmakoff, on account of his health, was gone to Urga, the Mongolian capital, to be near a native doctor.
