How many voting precincts in Texas?

There are over 8,500 precincts in Texas. I have been unable to find the exact number.

Travis county, in the 1960s, had one precinct that consisted of 60% of Travis county's population while another precinct in the same area comprised on 6%.

One precinct in the City of Midland contained 97% of the citizens. The 3% that were left populated the remaining 3 districts. (Texas Politics by Newell/Prindle)

As you can see, the size of precincts varies and is this variation is largely unchecked.
