In answer to several correspondents who have requested to know what book we can recommend, as giving a general and popular introduction to the _natural_ arrangement of animals, we are obliged to confess that amid countless volumes of anecdotes, compilations, and methods, no such work has ever been undertaken. With the intention of supplying this deficiency, we have devoted the greatest portion of the last five years to an Encyclopedia of Zoology; wherein the science will be placed under a new and striking light; no less instructive to the general reader, than interesting to the learned. In another year, we trust this work will be before the public. To _that_ volume we must consequently refer the readers of _this_, whenever they wish to understand the full scope and influence of those novelties in natural arrangment, which are but slightly glanced at in the following descriptions. As more than usual care is necessary in the binding of these volumes, it may be as well to mention that we have particularly instructed Mr. Betts, of Compton Street, Brunswick Square, on this subject. _Tittenhanger Green, 4th March, 1833._ * * * * * * [Illustration: TRICHOGLOSSUS _Swainsonii_. _Swainson's Green-lory._] TRICHOGLOSSUS Swainsoni. _Swainson's, or Blue-bellied Lory._ ---- Family Psittacidæ.

Mr. Caley, whose notes we now follow, says it a bird remarkable for docility and attachment to some people, although a perfect scold to others. When young they are caught by the natives, but from the loss of their favourite food seldom survive in confinement. An individual, kept by Mr. Caley, on being shewn the coloured drawing of a native plant, tried to suck the flowers, and it even made the same attempt with a piece of cotton furniture. Its scientific history we have already given elsewhere.
