SLIDE BULE. 240 SLOANE. shows the Nestler rule. In using this scale for luminosity which his master learned from Rera- niultiplication the figure 1 on the slide is made brandt, he patiently imitated the delicate brush to coincide with one of the two factors on the scale, the product then being found opposite the other factor as read on the slide. In divis- ion it is necessary merely to place the divisor read on the slide above the dividend read on the work and was able to use the outward manner of his teacher. Among his numerous works (some of them dated) are: "Family Group," in the National Gallery; "Male Portrait" (1656) and "Kitchen Utensils," in the Louvre; "Interrupted / //lll|l|ll|llll|ini|llll|TTTT]T i|m[|n[i|!iii|iin|i[ii|iiii|iiii|mnunii«iwTO^ P TH'T'SSff'wmiTfffffliP^ 60 61 iliiiiliiiiliniliiiiir i ' l y ' l f iii 'pl ] SLIDE BULE. rule, and the quotient will be found on the rule below 1 on the slide. For involution the num- bers on the upper scale of the rule are the squares of the numbers on the lower scale, and the cubes can be found by inverting the slide. The inverse of this gives the square and cube roots. On the reverse of the slide is a scale of sines and tangents, and a scale by the use of which logarithms may be found. SLI'GO.
