As an example of the character of the observations, which are relied upon by Homœopathists to establish this point, I will take Jahr’s Manual of Homœopathic Medicine published in 1838. It was ‘translated from the German by authority of the North American Academy of the Homœopathic Healing Art.’ This book is high in favor with all the Homœopathists in this country. It is a closely printed octavo volume of six hundred pages. Four hundred pages are occupied with descriptions of the effects of about two hundred remedies, and the remaining two hundred pages contain a Repertory, as it is called, in which the symptoms are arranged alphabetically, with the remedies which produce them opposite. The Repertory is of service in investigating cases, and, if we understand it, it is to be used in this way. A list is to be made of the symptoms presenting in any case, and then the remedies appropriate to the cure of these symptoms can be found opposite to them in the Repertory. The descriptions of the effects of remedies are exceedingly minute and particular. I will give a few examples, taken almost at random from the descriptions of a few articles. ‘_Drawing_ pain in _hollow_ teeth, extending to the eye-brows—cracked _upper_ lip—stitches in _hollow_ teeth, _when biting_—pain and pungency in the _elbow_, which allows one not to stretch or exert the arm—pungency in the knee and bend of the knee—inflammation and swelling of one _half_ of the nose—torpor and stiffness of one _half_ of the tongue (which half?)—blood blisters on the _inside_ of the _upper_ lip—loss of appetite chiefly for bread and tobacco-smoking—phlegm is hawked out, chiefly in the morning—rending and stinging in the _corns_—red itching spots on the _shin-bone_—tightening pain in the _joint_ of the elbow—blueish spots on the _fore arm_—tremor of the hands, when occupied with fine small work—tingling in the _points_ of the toes—tingling in the arms and _joints_ of the fingers—perspiration on the hands, and _between_ the fingers—stitches in the ankle _when stepping out_ (not when stepping in)—a voluptuous tickling on the _sole_ of the foot, _after scratching a little_, making a _man_ (woman too?) almost mad—ulceration of the _big_ toe, with a pricking pain—after stooping some time, sense of painful weight about the head, upon resuming the erect posture—an itching, tickling sensation at the _outer_ edge of the _palm_ of the _left_ hand, which obliges the person to scratch.’
