XXXII, 44.');"><sup>6</sup></span> Yet perhaps [the purchase is invalid] unless there is a deed [too], since it continues, and subscribe the deeds, and attest them? - Were 'acquire' written at the end, it would be as you say; now, however, that 'acquire' is written at the beginning,<span class="x" onmousemove="('comment',' I.e., before the mention of deeds,');"><sup>7</sup></span>
