The evidence
“His health being considerably impaired by overwork, Dr. Palmer attempted to resign in August, 1864, but the General commanding, in forwarding the resignation to the War Department, indorsed it with the request that a leave of absence of suflicient length of time to recruit his health be granted, " as the interests of the service demanded that officers of his ability and disposition should be retained." In the fall of 1864, he was appointed Medical Inspector of the Eighth Army Corps, with headquarters at Baltimore. He held this position until June, 1865, when he was ordered to take chargeof Camp Douglas, Chicago, 111., and close up the aiFairs of that hospital.”
