At this moment the respirations seemed wholly costal, and were performed with great effort, the elbows being jerked upward with every inspiration.

The paroxysm lasted about half a minute.

The act of swallowing did not appear to cause distress, for he could go through the motions of deglutition without any trouble.

The approach of liquid toward the mouth would, however, cause distress." It is to be remarked that the spasm affects the mechanism of the respiratory apparatus, the muscles of mastication and deglutition being only secondarily contracted.
Pasteur discovered that the virulence of the virus of rabies could be attenuated in passing it through different species of animals, and also that inoculation of this attenuated virus had a decided prophylactic effect on the disease; hence, by cutting the spinal cord of inoculated animals into fragments a few centimeters long, and drying them, an emulsion could be made containing the virus.

The patients are first inoculated with a cord fourteen days old, and the inoculation is repeated for nine days, each time with a cord one day fresher.
