The last-mentioned case is to my knowledge the first one of this type ever observed on man. The above-described heart actions will gain particular scientific interest, since they were written down with an electrocardiogram to the very end.

The experiments will be continued and extended. Another interim report will follow after new results have been obtained.

[Signed] Dr. Rascher
