BA' JAS. RENNIE, ESQ. M. A. 
Professor of Zoology , King’s College , London. 
The mere tyro in Entomology, or one who is just entering upon the study of 
this interesting branch of the science of Zoology, will here find a work well 
adapted to facilitate his pursuit. It not uufrequently happens, that persons who 
are extremel}' anxious to become acquainted with some particular science, are 
deterred from its investigation by the absence of a suitable guide to its first 
principles. To such persons we recommend Professor Rennie’s Treatise, in which 
the skin, members, external organs, and growth of insects, as well as their sys¬ 
tematic arrangement, are set forth in plain and intelligible language. The sci¬ 
entific terms are illustrated by figures; and in every possible way the author has 
endeavoured so to simplify the subject, that a diligent student may, in the course 
of a few evenings, become acquainted with its leading features. We observe, 
that in pages 18, 79, 80, and 81, the antennae are styled ears, and the thorax 
corslet; and some other terms are also introduced which may offend the more 
scientific portion of our readers. But the author’s design, as we have already 
intimated, being to adopt the utmost simplicity, as tending to more general uti¬ 
lity, we rather applaud than censure such a practice.

Culture of Cabbages by Slips. —The slips when taken from the cabbage- 
stalk, are exposed a sufficient time to the sun and atmosphere to cauterise the 
wounded part. In the summer twenty-four hours are sufficient, and two or three 
days in winter; rubbing a little wood-ashes on the part, as recommended by 
Mr. Lindlev, greatly assists in cauterising the wound, and prevents bleeding. 
Plant them, and they require no farther trouble. After cutting the cabbages; 
the sprouts again afford a supply of slips for plants, and thus a regular succes¬ 
sion of cabbages is secured throughout the whole year, with the certainty of pre¬ 
serving the quality of the parent stock unchanged, and of doing away with the 
necessity of raising plants from seed.— Card. Mag.
