A description is given of a form of mercury manometer which has the measurement arms in line with each other, has a very rigid construction and yet a loss in working range of only 3?5 cm. Where a cathetometer is used and where a large number of accurate readings must be made, such an instrument can save time and effort and can diminish sources of error.
