**Gelosia Method.** The method known as the 'gelosia',¹ has been described in the *Gaṇita-mañjarî* (16th century) as the *kapâṭa-sandhi* method. It appears also in Gaṇeśa's commentary on the *Lîlâvatî*. As the description of the *kapâṭa-sandhi* given by the older mathematicians is incomplete and sketchy, it is difficult to say whether Gaṇeśa is right in identifying the gelosia method with the *kapâṭa-sandhi* of older writers. In our opinion Gaṇeśa's identification is incorrect.²
