VII. fathoms, tliat was the temperature of the whole mass of water beneath, down to the greatest depth ; The temperature at 100 fathoms varies very little from 13° C. (555° Fahrenheit), and the Mediterranean attains in many places a depth of up- wards of 1,500 fathoms, so that here we have the strange phenomenon of an underlying mass of water, 1,400 fathoms deep, of a uniform moderate tempera- ture ; a state of things singularly different from that which obtains at like depths in the Atlantic. Dr. Carpenter's ingenious speculations as to the cause of this difference will be considered VAAY CHUKCH 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.
