of dysentery contracted on that expedition Mr. O'BRIEN never really recovered his health. After a severe illness he was invalided home, and his name first appears amongst the list of members of the Society in the December number of the Journal for 1878.
In the June number of the Journal for 1888 he published a most valuable paper on the obscure nervous disease of Latah, which is universally admitted to be an excellent attempt to elucidate one of the most interesting mental anomalies in the Malay character.
In No. 14 of the Journal Mr. O'BRIEN published some interesting notes on the History of the Constitution of Jelebu, accompanied by a sketch survey of the Sungei Triang which was published with Journal No. 15.

From that time Mr. O'BRIEN was no longer capable of much physical exertion and though he took a keen interest in everything connected with the Society he was no longer able to contribute in the way he would have wished, namely by personal observation and exploration of the Peninsula.
