In old Devanagari typography, 'ऐ' can be written as one stroke before/after and one on top, or 'शौ' is printed.
Wait, look at 'श्रोत्रिया': line 1, 'श्रो' has one vertical and one top stroke.
Here in line 32: look at the letter:
It has: श + vertical stroke to the right + two slanted strokes on top! That spells 'शौ'!
Wait, or is it 'शै'? Some fonts write 'शै' with a vertical stroke on the left/right? No, 'शौ' is often a typo for 'शैत्य' or printed as 'शौत्य'. Let's look closely: it's definitely 'शौत्यानुमानादौ'.
