The Common Tape-Measure.—A common measure thirty-six inches in length, fixed in a small German-silver box, and made to act by a spring, will be found useful in the liseasea of the lungs. To ascertain the circum- , tape round it, over the region ?i the nipples; should the patient have his shirt and flannel kel on, we must make an allowance of a quarter of an inch for each of these articles. To learn the mobility of the ', we pass the measure as just directed, request the patient to fill his lungs as much as possible by taking a deep inspiration, and note the number of inches on the measure, Una being oi course the greatest circumference: we then wi hout moving the tape, make him expire to his utmost, and noting the number of inches, we shall have the minimum circumference; the difference between the maximum and minimum will give us the mobility of the chest. In healthy Persons, of orS.nary weight and middle age, the average mobility is three inches, very rarely extending to four. ° for,!nS?Tetei'~An i'^trument, called a stethometcr, nieasuring the expansive movements of the thorax during ' ;i:Mt.m., and for ascertaining the difference in the mobilitf ' °P Oi the chest, has been invented by Ur Sard Quain.
