An introduction containing : A) General information in regard to materiel, ammunition, an sights. Explanations in regard to the use of the tables. 2. Three charts as follows : For finding the barometric pressure at the battery from the data furnished by the meteorological station. Showing the variations, in milligrams, in the weight of a liter of air with respect to the normal weight of 1 gr. 208, as a function of the tem- perature and barometer. Showing, for a given wind direction expressed in grades, the longitudinal and cross components with respect to the plane of fire. These charts follow the introduction. 3. Tables, printed on white paper, giving data common to all projectiles. These are : ) Table I. - Sites, in minutes and hundredths of minute, for various ranges and a difference in altitude of 1 meter. B) Tables IIa and 11b. - Complementary site corrections, in degrees and minutes, for various sites and elevations.

Some idea of the values to assume for dV₀ may be obtaîned by systematic study of the record of the piece and the powder, to whateve extent circumstances permit. This might be done as follows : The ajusted range is stripped of the conditions of the moment, as far as known, that is, corrected to tabular conditions. The difference, stripped range less map range, is attributed to a variation of velocity, V - V₀ - dV₀, called the velocity correction. This velocity can be used, together with new conditions of the moment, to correct the map range for subsequent firing. It is also possible to use an adjustment coefficient, K₀, the ratio stripped range , multiplying by this coefficient the map range for sub- Charts. sequent objectives and correcting for new conditions of the moment. map range But, in all cases, the firing data determined in this manner can only be considered as a first approximation. No precision firing can be done, as far as these elements are concerned, without their being checked, and generally corrected, by firing for adjustment. IC1. Baromeler.

PAPILLON N° 6. (1) Cette correction est indispensable en part culier si le tir fusant a été précédé d'un ré- glage en tir percutant.

Or, l'expérience a donné une portée moyenne de 6,382 mètres, soit un écart de 3 mètres, alors que la différence entre la portée tabulaire et la portée expérimentale est de + 74 mètres. La concordance entre la portée évaluée d'après les tableaux de correction et la portée expérimentale est donc très satisfaisante. PAPILLON N° 8. FUSÉES COURTES.
