<thinking>Let's approach this step-by-step:
Let us think through this logically (CoT):

Step 1: What is the task requiring me to do?
Find the number of character "s" in the word "Thymus"

Step 2: Break down the word.
T-H-W-M-U-S


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Thymus", not "thwmus". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. T
2. H
3. Y
4. M
5. U
6. S

Step 5: Determine the positions of the letter "s".
The letter "s" appears at the 6th position in the word.

Step 6: Sum up the letters.
Y: 1, T: 1, M: 1, U: 1, S: 1, H: 1

Step 7: Inspect the letters we enumerated.
The selected letter was "s" and there were 1 overall.

Result:
The letter "s" is found 1 instance in "Thymus", at the 6th position.</thinking>
