The application of the exact methods of modern science to this line of inquiry is new, and it will require long and patient work to bring it to per- fection. The one real advance whicli has been made in this direction is the addition to the appliances for the investigation of the physics of the deep sea; of a correct and trustworthy instrument by which ocean temperatures can be ascertained to aoy depth with what may be regarded as absolute accuracy for all practical KUKO, PROM VAAY IN Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thomson, C.
