2. **Identifying Symptoms**: One of the key symptoms of tertian malaria is the occurrence of paroxysms, which are recurrent attacks of fever.

3. **Frequency of Paroxysms**: In tertian malaria, these fever attacks occur every second day. This means that the paroxysms happen after a specific interval of time.

4. **Determining the Time Interval**: The interval at which these paroxysms occur is 48 hours. This means that after the initial fever, the next attack will occur 48 hours later.
