Note 1135 — Chapter VII · (continued 2)
Reading edition
See an admirable statement of the three forms of decrement, in Haüy, Traité de Minéralogie, vol. i. pp. 285, 286. Compare Whewell's Hist. of the Induc. Sciences, vol. iii. pp. 224, 225; who, however, does not mention Haüy's classification of ‘décroissemens sur les bords,’ ‘décroissemens sur les angles,’ and ‘décroissemens intermédiaires.’
