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 - [Previous: v1.c3.s17.23](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s17.23) - [Next: v1.c3.s17.25](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s17.25) - [Up: v1.c3.s17](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s17) --- Source: [https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s17.24](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s17.24) · Pramāṇa
