Dr Moore introduced Mr T. Leddra, aged sixteen years, to exhibit his talent for mental calculation. The following questions were proposed to and answered by him:-1. What is the square root of 127,449 ? Answer, 357; given in threequarters of a minute. 2. What is the cube-root of 389,017? Answer, 73; given in half a minute. 3. What is the product of 537 by 392? Answer, 210,504; given in half a minute. 4. What is the product of 38,465 by 72,649? Answer, 2,794,443,785: this question took him more than ten minutes to solve.

The organ of Number, so evident in the casts of Bidder, Colburn, and Noakes, did not, in this instance, seem to be greatly developed; and it appeared from Mr Leddra's own statement, that he had not possessed this power of calculation till about four years ago, that he had been under the tuition. of an eminent master, and that the figures as they appeared on paper were strongly represented to his mind.

Mr G. Bidder, who was present, on being asked from the chair, whether he considered Mr Leddra to perform his calculations by the same means which he himself employed, replied, that it was evident that the power had been acquired by Mr L. in a manner totally different from that which had been early and spontaneously manifested in himself and Master G. Noakes, who was examined by the Society at a previous meeting. They neither associated the numbers with figures nor words, but possessed an intuitive perception of the proportions of quantities themselves. On being requested to explain some of the processes by which he was assisted in his calculations, Mr Bidder said, that he could tell immediately, without any effort or calculation, the product of any two numbers below four figures each, as his mental multiplication-table extended to a thousand; that when the numbers exceeded three figures, he always began with the highest numbers, as, by so doing, he was enabled to add without carrying; that he had an instantaneous perception of the best among several modes of performing the same operation, and that he frequently availed himself of the peculiar properties

of certain numbers. With a view of putting to the proof the unimpaired state of Mr Bidder's extraordinary faculties, Mr Palmer proposed the following questions to him:—1. Suppose a railway, whose inclination is 1 foot in 300, the friction 1-200th of the weight, the carriage 1-3d of the load, the horse to employ a force of 150 lbs. at 24 miles per hour, and the carriage to be loaded with pills, each weighing 5 grains, troy weight, how many pills will the horse take up? Answer, 13,824,000. 2. How much would these pills cost at three farthings each? Answer, L.43,200. 3. Suppose a man to work 10 hours per day, and to make 15 pills in a minute, how long would he be making them? Answer, 1536 days.

The first question was solved by Mr Bidder in twentyeight seconds, and the remaining questions in three-quarters of a minute: the whole was accomplished in less than one minute and a quarter.

Mr C. Pemberton was introduced by Dr Moore, and exhibited specimens both of his poetic and histrionic talents. The subject proposed to exemplify his faculty of conception and talent for versification, was the fall of Missolonghi, which he prepared and recited to a crowded auditory on Saturday evening.

The following gentlemen were elected ordinary members:R. H. Black, LL.D.

James Scott, M.D.
J. P. Greaves.

A. L. Irvine.

Mr Simpson, of the Edinburgh Phrenological Society, delivered a message of congratulation from the members of that institution; and, in a speech of considerable length, expatiated on the utility of Phrenology, and the accessions of knowledge to be derived from its cultivation by collective bodies. He concluded by expressing his warmest wishes for the success of the London Society, and by assuring the meeting of the cordial co-operation of the Society of Edinburgh in every plan that might be suggested for the acquisition and dissemination of phrenological knowledge.

Dr Elliotson spoke in reply, and assured Mr S. of the reciprocal good feeling which existed on their part towards the Edinburgh Society. He then announced, that the collection of casts, books, &c., belonging to the Society, would be placed in the rooms on the ensuing meeting, and hoped that, by the donations of the members, and the application of the funds of the Society, a commencement might be formed of an extensive and valuable museum and library, to which the utmost facility of access might be given to the members and their friends.

Dr Wright, in praising the exertions of the Edinburgh Phrenologists, introduced some animadversions on those points in which they differ from the conclusions of Dr Spurzheim. The auditors' report was brought up and read.

June 1.-James Simpson, Esq., advocate, Edinburgh, was elected a corresponding member.

The following gentlemen were elected ordinary members:George Mason, Surgeon.

J

Arthur Symonds.

Henry Debell Bennett.

Presents were made to the Society by Dr Poole, Dr Elliotson, and Mr Hawkins.

Dr Poole exhibited the skulls of a Gipsy and an African Negro, and pointed out the characteristic resemblances of the former with those of the ancient Egyptian race. Dr Poole also exhibited the crania, and described the characters of several dogs of different species, with whose dispositions he had been familiar when they were living.

A skull discovered in a vault under the ruins of Hastings Castle was exhibited; and historical evidence was adduced to prove, that it had belonged to one of the earls of Augi, who possessed the castle from the time of William the First (by whom it was granted to Robert, Earl of Augi, who accompanied him from Normandy,) till the time of Henry II., in whose reign it was escheated to the crown, and converted to a religious house.

ARTICLE VI.

OBSERVATIONS ON SOME RECENT OBJECTIONS TO PHRENOLOGY, FOUNDED ON A PART OF THE CEREBRAL DEVELOPMENT OF VOLTAIRE.

A BUST of Voltaire has lately become common in the shops, and it appears to be the original of the well-known engraving of that person in Lavater's works. The development and combination of organs which it presents are, in many respects, so singular, and differ so widely from all others which we have seen, that no statuary or modeller would dream of compounding such a head; while, nevertheless, it bears the strongest stamp of nature in its details, and corresponds in so remarkable a degree with the mental character of Voltaire, that we are strongly persuaded that it is a correct representation of the head of that person in his old age. Some years before the death of Voltaire, a statue to his honour was erected by subscription, to which several monarchs contributed; and it is probable that this is the bust of that statue. Although, however, we assign these reasons for holding this bust to be genuine, we are not particularly interested in that question in so far as regards our present object. It has been assumed by some of our opponents as an exact transcript of nature, and founded on by them as shaking Phrenology to its base, (for with them every objection, however small, always destroys the whole fabric of our science,) because it exhibits a large organ of Veneration. Yes, the head of Voltaire, the most celebrated of infidels, and more, the most violent and implacable enemy of Christianity, the imaginer and unwearied prime mover of a deep and dark conspiracy, with the Condorcets and the D'Alemberts, to root it out in Christendom, and extinguish its very name, the malignant inventor of an appellation of keen re
