(Here are two typical cases out of thirteen by Dr. W. H. Burt, which we find in the _North American Journal of Homoeopathy_, 1866, quoted from the _Medical Investigator_ from a volume not attainable.) CASE 1. Intermittent fever: Type Quotidiana Duplex. In a large lymphatic woman; weight about 180 lbs.; aged thirty-nine. November 4th. For the last five weeks has had the ague. At first it was a simple quotidian. Took Quinine, which broke it for four days, when it returned; took Quinine in massive doses, which checked it for one week. It returned two weeks since, in the form of a double quotidian. The chill comes on every day at 10 A.M. and 5 P.M. The chill lasts from one to two hours each time; hands and feet get icy cold, chills run up and down the spine, with severe pains in the head, back and limbs; followed by high fever for three hours, and then profuse sweat. Tongue furred whitish-yellow, with large fissures in the tongue; flat, bitter taste; has had no appetite for five weeks; craves cold water all the time; bowels rather costive; has nausea during every chill, but no vomiting; very weak, can only sit up about one hour in the morning; great depression of spirits, cries during the whole examination; face very much jaundiced. Treatment: _Ars. 2_, every two hours, for three days. It produced constant nausea and lessened the chills, but aggravated the fever. I then determined to try the _Boletus_ 1st, two grs. every two hours. Took two doses when the chills came on, she then ceased to take the medicine until 5 P.M. Took three doses, and then fell asleep. 8th. Says she is feeling a little better, continued treatment; 10 A.M., commenced to have a severe diarrhoea, an effect of the medicine; discontinued the powders until 5 P.M. The fever did not come on until 3 P.M.; had no chill; fever lasted three hours; perspired profusely all night; slept well for the first time in a number of weeks. 9th. Feeling much better. Fever came on at 4 P.M., had no chill; fever lasted four hours; nausea all the evening; sweat all night. 10th. Feeling quite well. Had no more fever, but had night sweats for a week after. Convalescence was very slow; notwithstanding she had no more fever it was three weeks before she felt perfectly well. This case demonstrates the fact to us that the _Boletus_ is superior to our _greatest remedial_ agents in the case of intermittents. I believe if I had not been acquainted with the therapeutic properties of the _Boletus_ I would have been compelled to treat this lady every few weeks for two or three months with our usual remedies.
