I've only just arrived <a href=" http://www.ashbrookarms.com/what-is-mirtazapine-30mg-tablets-used-for.pptx ">mirtazapine 45 mg overdose</a> But I&rsquo;m mighty glad that crayfish don&rsquo;t live on land. The American signal crayfish was only introduced to Britain in 1976 but is now a key fixture of summertime in our parish: it has so many pairs of legs, plus claws, antennae and all kinds of alienesque furry bits; having to fish one out from under the bed with a broom and a torch wouldn&rsquo;t be much fun. They&rsquo;re not very big, about as long as a hand; it&rsquo;s their numbers that terrify me. The local rivers are absolutely teeming with them &ndash; they&rsquo;ve almost completely ousted the native species.
