Query: well written and worthwhile

it is unfortunate the authors did not review the most recent scientific style and format conventions of the council of biology editors(accepted internationally) that were published in 1994. had they done so, they would not have made a number of the errors that show up scattered about in the text. i use parts of this text , especially the exercises, in a course i teach on scientific writing and have to make the corrections as we go along
