CASE VII. Mrs. D., aged twenty, a healthy, stout lady, mother of one child, had been always enjoying good health, was suddenly attacked with a violent fit of asthma on the 8th of August, 1890. This was the first occasion she had a fit of asthma, the result of a severe cold. At about 2 A.M. she was suddenly seized with difficulty of breathing and a great oppression in the chest. She could not lie down any longer in bed and had to sit up, being supported on a pile of pillows. In the morning at 8 A.M. I saw her first. I noticed she was in great agony and almost speechless. On examination I could not detect much loud wheezing--the characteristic of an asthmatic attack--though the rapid movements of the walls of the chest were even quite visible to the bystanders. The patient was feeling almost choked up, and could not express what was going on. She only pointed out a point, a little over the pit of the stomach most painful. There was no cough--perspiration was pouring over her body. I could not at once make out whether it was a case of pure asthma, especially as she never had it before. However, I made up my mind to give her _Blatta orientalis_ IX trit., a grain dose every fifteen minutes, and watch the effect myself. Three doses of it were given without much change for the better. I left a few more doses to be repeated half hourly and promised to see her again within a couple of hours. On my return I found her in a much better condition, and she had taken only one of those powders I had left, and they were not repeated, as she felt better. Now I thought it must have been an attack of asthma, and I continued the medicine unhesitatingly. There was no aggravation at night, but on the next morning she was better, and the usual asthmatic cough began with slight expectoration. There was pain in the chest and head with each coughing fit. _Blatta orientalis_ 3x trit., four to six doses, was continued for a few days, when she got well. Again in November she had a slight tendency to an asthmatic fit, took two or three doses of the same medicine and got well. Since then she had not been troubled again.
