Abstract
A report on the temp. and pH of 120 hot springs in Wyoming, Idaho, Oregon, Utah, Nevada, California and New Mexico; with chemical analyses, sp. gr., and salinity of some; a systematic discussion of all spp. of Protozoa, Nematoda, Crustacea, Acarina, Insecta, Mol-lusca and Vertebrata found; and in the case of many spp. tables of the temp., sp. gr., and pH of the water in which found. The upper limit compatible with animal life is approximately 50[degree] C; the highest actual records were for the thermal mite Thermacarus nevadensis at 50.8[degree] C and 2 records of the ostracod Potamocypris perbrunnea at 49-50[degree] C. Among higher plants the highest record was of Distichlis spicata, with roots in water at 52.5[degree] C. The number of spp. decreased with each higher degree of temp. The number of spp. increased with increase of pH up to 8.4, thence rapidly decreased.
