having been drawn on to a great extent. Sufficient reasons are given 

 for including Arachnids in the work, although the title speaks of 

 insects only. The classification of the insects we are bound to state 

 is very inadequate and out-of-date. One would like to see technical 

 terms [e.g. pollination, fertilization, animal, nymph) used with a 

 definite meaning. The last, for instance, is now usually applied to 

 the whole stage between ovum and imago of insects, such as dragon- 

 flies, with little post-embryonic development. The book has not been 

 at all well seen througli the press, the slips in spelling and solecisms 

 in expression being numerous. In a few places errors and questionable 

 statements have crept into the matter. W T T
