Bulletin . e minutes as indicated by the X in the graph. Graph 28 shows the positive reaction of a full-grown rock bass to two cc. perliter of sulphide. The pure water was encountered repeatedly and re-peatedly avoided. Graph 29 shows the reaction of two orange-spotted sunfishes tO cc. of sulphur dioxide per liter. The fishes spent the greater part of the timein the central part of the tank. Graph 30 shows the positive reaction of two orange-spotted sunfishes to 5 cc. ofsulphur dioxide per liter. Graph 31 shows the positive reaction of a long-eared sunfish to water
Bulletin . e minutes as indicated by the X in the graph. Graph 28 shows the positive reaction of a full-grown rock bass to two cc. perliter of sulphide. The pure water was encountered repeatedly and re-peatedly avoided. Graph 29 shows the reaction of two orange-spotted sunfishes tO cc. of sulphur dioxide per liter. The fishes spent the greater part of the timein the central part of the tank. Graph 30 shows the positive reaction of two orange-spotted sunfishes to 5 cc. ofsulphur dioxide per liter. Graph 31 shows the positive reaction of a long-eared sunfish to water containingless than 1 cc. per liter of carbon disulphide. Graph 32 shows the reaction of a minnow (Pimephales) under the same con-ditions as graph 31. The fish was positive during the first seven minutes and nega-tive during the last three. Graph 33 shows the positive reaction of a rock bass to a fatal concentration ofthiophene. Graph 34 shows an equally positive reaction of a long-eared sunfish.
