In the reports the following rules and conventions were observed. The numbers in bold type preceding the name of the glaciers are those of the «Catasto dei Ghiacciai Italiani» (Inventory of Italian Glaciers), 4 voll., Comitato Glaciologico Italiano, 1959-1962, and subsequent variations. The numbers in bold type that countermark photographs and figures correspond to those of the glacier inventory. In addition to the subject, the photographic station, the format of the negative, the focal length of the lens, the date and the author are also indicated. The letters, sometime in pairs, between brackets and small, placed next to the symbols of the signals, have the following meaning_ c, centre; d, right; s, left; f, frantal; l, lateral. The symbols (C), (T) and (A) indicate that the altitude they refer to, always expressed in metres, has been derived from the topographical map, determined topographically or obtained with an altimeter, respectively. In the tables summarising the variations of each glacier the distances, expressed in metres, are approximated to ± 0.5 m and are intended as real distances. Unless otherwise indicated in brackets, previous distance means that of the year 2016. Variations are indicated with the following symbols_ - retreat; + advance; - X not quanti/iable retreat; + X not quantifiable advance, O stationary glacier; ? uncertain variation; SN snout covered by residual snow; NM not measured
