The appearance of the half-volumes at intervals of six months, insures for any communication almost immediate publicity; whilst the shortness of the time between its reception and publication, is a guarantee to the public that the whole of the paper was really communicated at the time it bears date.

To this may also be added, the rarity of any alterations made previously to the printing, a circumstance which ought to be imitated, as well as admired, by other societies.

There may, indeed, be some, perhaps the Geological, in which the task is more difficult, from the nature of the subject.

The sooner, however, all societies can reduce themselves to this rule, of rarely allowing any thing but a few verbal corrections to papers that are placed in their hands, the better it will be for their own reputation, and for the interests of science.
It has been, and continues to be, a subject of deep regret, that the first scientific academy in Europe, the Institute of France, should be thus negligent in the regularity of its publications; and it is the more to be regretted, that it should be years in arrear, from the circumstance, that the memoirs admitted into their collection are usually of the highest merit.

I know some of their most active members have wished it were otherwise; I would urge them to put a stop to a practice, which, whilst it has no advantages to recommend it, is unjust to those who contribute, and is only calculated to produce conflicting claims, equally injurious to science, and to the reputation of that body, whose negligence may have given rise to them.
