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

Step 1: What is the task requiring me to do?
Identify the occurrence of letter "s" in the word "Perspicacious"

Step 2: Dissect the word.
P-E-R-S-P-I-C-A-X-I-O-U-S


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

4. S
5. P
6. I
7. C
8. A
9. C
10. I
11. O
12. U
13. S

Step 5: Pinpoint the positions of the letter "s".
The letter "s" appears at the 4th, 13th positions in the word.

Step 6: Quantify the letters.
P: 2, A: 1, E: 1, R: 1, U: 1, S: 2, I: 2, O: 1, C: 2

Step 7: Evaluate the letters we counted.
