" After hiving paid considerable attention to electricity in general, it appears to the (says Mr. II.) that caloric and the dc composed water of the galvanic trough, constitute the galvanic This expression ij altogether unintelligible. Farther am, he ob'erves that " water, which has but little resen;tilaime the galvanic fluids; may be so far changed by its union with ca lorie, us to bear a much Wows' similarity to those ai , ,ents ; for when united to a certain portion of calorie, it becomes so dilat ed as to occupy about 000 times the spare it did in the character of water." The relative volume between water as a liquid and aquatic gas (or steam), if I may be indulged the expression is very incorrectly stated ; and if it were otherwise, we do not see why the galvanic energy is heater eiqlaieed by reference to steam in the way of elucidation. Dr. Garnett had observed Ia his lectures on . Zoonomia, that G 6 what the nature of the galvanic fluid is we are ignorant. Same experiments had led him to suppose that it may be hydro gen, which, when comhined with caloric, appears in the form of gas, but when pure, or in a different state, may be i.lpable of passing through solid bodies in the form of electricity. Aud Mr. Sylvester's notions are, that the galvanic fluid is electrated hydrogen, or a chemical combination of the electric fluid with hydrogen itself, w hich is the theory of Dr. Bostock and some others. The experiment made with Mr. Byewater's galvanic .trough appears to prove nothing, still less his own singular and unsupported Itypoetesis, that " oxygen forms the base or posi• tive galvanism, and hydrogen that of negative." Mr. Bye water is farther inclined to suppose that the net: rzetal.obtained by Messrs. Gay, Lussae, and Thenard, w ithout the aid of gal vanism, is the oxi , lated iron of the apparatus imperfectly re stored by the ;dean employed, and not a (new) metal derived • from the alcali by the action of the heated iron." .

THE .eXPEDI'IION. SEPT. 10. "SotiTH nVvELAND, .AUG. '26,—" I understand you are all perfectly satisfied in England with our success. l ant glad of it, for it is more thau we are here. In fact, I •da'not believe there ever was any army more dissatisfied than this ; w e are ithsAutely ashamed of ourselves, and half of us arc think it of ways aed weans to get back unperceived, and to pass eurselveu off as quite unconcerned in the Expedition. Forty thousand men to take a place of about ten miles in circumference, in a fortnight, or about that ! Alas ! i.lits! Besides, vi hen w e ar rived on the coast, the places were alefeuceless ; but we were too generous to attack an unprepared enemy , and therefore we laid formal siege to Flushing, wit one half of our army, the other was kept on board ship, or landed here in South Beve land, and sent into cautoninents, to pass the time in shooting and other amusements, until all tiece-nary preparations had been made for the defence of Antwerp, the capture or destruction of the fiect at this place, was the principal object , of sending tit nut, for NValchereu was merely occupied to secure our retreat. Far ililrerent was the conduct of the trench. After thus reco ‘ering from their first panic, they were indefatigable- in con structing works and collecting reinforcements. Every day fresh f;enerals and troops and guns arrive upon the coast. W het) at last it aas thought fit to begin to think of proceeding, it was, I believe, found, after immense fuss, that the thing was impossible. The opportunity had been suffered to slip through our fingers ; and the enemy with whom we have to deal is too active to al low us to regain it. The boa thin; we can now do, is, therefore, to go hack again; at least that is said to be the prevalent ,-opinion of a Council of - war, to which all the lieutenant-generals were surammied.. If this resolution has been formed, it would be well to execute it without loss of time, as it is uuderstood that the enemy are marching down an immense army to this evast,and it may be a favourable opportunity to go somewhere c?se. The army, besides, begins to get very sickly. The 9atit have one huudred and sixty ill, and the others are aliected in the same proportion. Flushing is a dreadful example of the calamities of war. It is, in fact, nothing but a heap of ruins.-- t was a very pretty city. But not hang can equal Middleburgh, the capital of the ibliand; it is one of the most beautiful towns I ever saw. The country altogether is very tine; but the people fiat and insipid in the extreme." PRO INCI4L S. - "-`WIEBIft -- At Chester Assizes, which ended on Thursday sennight Thomas Newton, a labourer, was tried under the 42d. Geo 111. commonly caNd Lord Elleaborough's Act, for giving medicine to I;lizabeth Turner, to procure almuion ; and received the mitigated sentence of three years imprisonment in the county gaol, at the end of that time to pay a tine of 1001. to the King, and to be imprisoned till the tine is paid. Dr. Thackeray, of that city, who was examined as an evidence on the trial, clearly stated, that medicine given to procure alaortion, could not be ad ministered without endangeringa he life of the female.—Thomas Siddall, aged 56, a labourer, was convicted of indecent practices towards several young females, and sentenced to be imprisoned two )ears in the common gaol, and during that, bet ween the hours of twelve and two, to be set in and upon the pillory, un a market day, at Glover's-stone. - SHOCKING EvENT.—llenry Baylis, about four years of age, was on Wednesday se'onight murdered by his mother, Hannah of nishop'. Clee%e, Gloucestershire, who, in a violent fit of insanity, beat out his brains. She had previously at tempted to destroy t %I") others of her children, one by cutting its throat, which only failed from the bluntuess of the \ knife ; and the other was happily rescued from her grasp, at the mo ment, when she was going to break his hack across a window frame I It was during the confusion occasioned by this awful scene, and before she could he secured, that she murdered the poor ienocent first mentioned. On titualavcvening last, as William Greenwood, a labourer its the parish of Aldershot, Hampshire, was in the act of instruct ing his children in the Church tBtechi3ot, on coming to the tsords ' thou shalt . do no murder,' he immediately jumped up, went into the garden, and %%as seen to slide. easily lugs the welt. Assistance was immediately had, but the well being remarkably narrow, it wAs with difficulty that he was drawn up, and when taken out he was quite dead Nu reimauu is given fur this futdit cuutluct.
