‘on the other—i.e., next, day’). The *ubhaya-dyuḥ* (‘on both days’) variety appears to mean a disease recurring for two successive days, the third being free; this corresponds to the *rhythmus quartanus complicatus*.¹⁴ But Sāyaṇa considers that it means a fever recurring on the third day, the ‘tertian.’ The *tṛtīyaka*, however, must be the ‘tertian’ fever,¹⁵ though Zimmer¹⁶ suggests that it may mean a fever which is fatal at the third paroxysm. Grohmann¹⁷ regards the *vi-tṛtīyaka* as equivalent to the *tertiana duplicata*, a common form in southern countries, in which the fever occurs daily, but with a correspondence in point of time or severity of attack on alternate days. Bloomfield¹⁸ suggests that it is identical with the *ubhaya-dyuḥ* variety. The *sadam-di*¹⁹ type appears to be the kind later known as *saṃtata-jvara* (‘continuous fever’), in which there are attacks of several days’ duration, with an interval followed by a fresh period of attack. Fever occurred at different seasons, in the autumn (*śarada*), in the hot weather (*grīṣma*), in the rains (*vārṣika*),²⁰ but was especially prevalent in the first, as is indicated by the epithet *viśva-śarada*, ‘occurring every autumn.’²¹
