PREPARATION.--The fresh bark and young twigs are pounded to a pulp and macerated in two parts by weight of alcohol. (The following proving of this remedy was made under the supervision of Dr. F. H. Lutze, Brooklyn. The _Cornus alternifolia_, or "swamp walnut," has a reputation among the people in certain localities as being a "sure" remedy for "salt rheum.") FIRST PROVING BY R. E. ALBERTSON. Commence at bedtime Tuesday, May 12, 1896. Wednesday, May 13, 1896.--Awoke this morning after a very refreshing night's sleep, feeling as well as usual; and did not notice anything out of the ordinary during the entire day. Had stool, but somewhat scanty. Appetite fair. Thursday, May 14, 1896.--Did not rest very well during night. Had dream I was spending summer in country. Did not get into anything like a sound sleep until near morning; and then was very reluctant about getting up; would have preferred to have had a couple hours more of such sleep. I have noticed nothing in the course of the day worthy of mention excepting a pain across the small of the back, which lasted only a short time and then disappeared. Stool to-day little better than yesterday. Friday, May 15, 1896.--Another restless night; would get into a light sleep off and on until near morning. Dreamed again; this time of an exciting fire drill. Up to to-day had been taking _Cornus alternifolia_ thrice daily; 3 drops 30th, commencing with this morning every three hours. Stool to-day at first hard and difficult, then loose. Nothing further noticed to-day. Saturday, May 16, 1896.--Passed a very restless and sleepless night; guess I was awake at the striking of every hour. Tongue has been coated a yellowish white for a couple of days. Stool to-day, but scanty. Feel as well as usual, but don't seem to have the ambition to do anything for any length of time. Sunday, May 17, 1896.--Experienced another very restless and sleepless night. Felt an aching in left shoulder and dull pain across forehead, more particularly on right side. Stool to-day and appetite fair. Monday, May 18, 1896.--While I passed another restless night, it was not as bad as nights previous. Seem to hear every little noise and sound. When once awake, mind becomes active and then it is difficult to get into a sleep again. Have dreamed something mostly every night; some of which I do not remember. Tuesday, May 19, 1896.--Rested somewhat better last night; though was awake off and on. Last dose taken at bedtime. Wednesday, May 20, 1896.--Experienced another restless night; was awake most of the night until about 3 A.M., when I dropped off into a sleep.
