The nursery water was the best, when microencapsulated diets of "OK" and rotifera were blended at the percentage of 80% and 20%, the nursery water quality was the best during the rearing period, the highest concentration of NH3-Nt (NH3-Nm) was 1.025mg/L (0.0836mg/L),and the highest concentration of NO2-- N was 0.0236mg/L. When larvae emerged, the concentration of COD was 1.526mg/L, Puyrrop Hta was 1000 Entries/ml, and the metamorphic rates of all periods exceeded symmetrically 97%, and the survival rates also higher than the control group fed pure crude diets.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
