Determine the rhyme scheme of the following poem.
Thou ill-formed offspring of my feeble brain,
Who after birth did'st by my side remain,
Till snatched from thence by friends, less wise than true,
Who thee abroad exposed to public view;
Made thee in rags, halting, to the press to trudge
Where errors were not lessened, all may judge.
At thy return my blushing was not small,
My rambling brat (in print) should mother call
