Mips, how to get the second value in one .word using an offset with lw

I have this code

size:   .word 8 9

I would like to get the 9 and store it in a register, so far I have tried this 

lw $a0, size    
lw $a0, 4(size)

But I don't think I am using the right offset number, how do I get the 8 and the 9 from this .word and store them in seperate registers

To load an address, use la, not lw. Then, go 4 bytes past it.

la $t0, size
lw $a0, 0($t0)  # 8
lw $a1, 4($t0)  # 9

Additionally, as @Eraklon said, comma-separate your .word directive:

size:
    .word 8, 9
