of the Apothecaries’ Company. It commands a, good class,but, as may be predicated, principally of one religious denomi-nation. From what has been written it will be seen that themedical classes of Dublin, in the aggregate amounting to from800 to 1000 each year, have plenty of hospital and school ac-commodation at their disposal.

THE CHOLERA.

THE cholera still spreads in Italy. In Barletta (SouthItaly, province of B,ri; population in 1862, 26,952), whichsuffered from the epidemic in 1865 and 1866, the disease pre-vails with greater severity than in the former years. Trani

(population, 22,702) and Corato (population, 25,000), in thesame province, have also suffered much. In Corato no lessthan 2000 persons have fallen victims. The latest news statesthat the disease is extending to the inland portions of the pro-vince, and that it has appeared in Minervino (population,13,590), Pinazzola and Canosa (population, 12,894). In eachof the latter-named places the deaths numbered at the end ofJune from twenty to twenty-five daily. Cholera also exists inthe Capitanata.Towards the close of June cholera broke out in the village

of Castagnetto di Cava, between Naples and Salerno. Fivecases and two deaths were returned on the first day of the e out-break. Cases also have been reported in neighbouring villages.The disease has, moreover, appeared in several places of theprovince of Caserta.

In Northern Italy cholera is officially stated to have brokenout in June at Cuneo and Alba in the southern, and at AostaTorea and certain villages in the northern division of the pro-vince of Turin. In the city of Turin, to July 5th, fourisolated cases had occurred, all the attacked being individualscoming into the city from the country. Of the places affectedin the province of Turin the following particulars are re-

ported :-In Ivrea, a town of about 9000 population, from 8to 10 cases have occurred daily during July. On the 29th ofthe month 25 cases and 13 deaths were reported. At Cigliano,a village of 5000 inhabitants, district of Zercelli, 458 cases,resulting in 206 deaths, took place in forty days. At SalettaCanavese (?), a village of 500 population, 70 cases and 40deaths occurred in fifteen days. At Maglione, population 1000,40 deaths took place in fifteen days. The Gazzetta Lombardastates that cholera appeared in the Southern provinces towardsthe beginning of May last, and has since spread to almost allparts of the country. In the town of Brescia and surroundingdistricts Dr. Rodolfi has reported, up to June 25th, 982 casesand 400 deaths. In Bergamo, during the same period, therehave been 1932 cases and 961 deaths. On the 9th of JulyBrescia and its neighbourhood counted 2545 cases, of which1115 were fatal; and the town and province of Bergamo 4224cases, and 1892 deaths. At Cremona, Como, Ancona, Turin,and Palermo, scattered cases have been observed; but the epi-demic rages especially in the province of Vercelli and Aosta(Piedmont), where, up to June 29th, there were 845 cases and422 deaths, and from that date to the 5th July the cases were468 and the deaths 206. Milan has been remarkably spared,for the report presents only 11 cases from the 14th June to the12th July; these cases were, however, of a very severe kind,as no less than 8 were fatal. The ammonio-citrate of iron hasbeen largely tried, in doses of fifteen grains every hour; butfrom the above-mentioned mortality, it does not seem to havebeen particularly successful.News from Ragusa, dated July 2nd, reports the alarming

increase of cholera in the vicinity of that city, and in Mon-tenegro. The town of Ragusa was free from the disease, butin a neighbouring village 40 cases had taken place. In the

Trebigne district and Bielo (?) padowich, in Montenegro, thedeaths from cholera have amounted to several hundreds.The following are the latest returns from Sicily :—

The following is a return of the deaths from cholera anddiarrhœa, in London from the twenty-sixth to the twenty-ninthweek of the present ycar inclusive, and in the correspondingweeks of 1866:—

Of the 23 deaths from cholera or choleraic diarrhoea in the last

two weeks, 2 only were adults; and of the 170 deaths fromdiarrhœa in the week ending 20th July, 162 were children.CONVERSAZIONE AT THE ROYAL COLLEGE

OF PHYSICIANS.

A LARGE and distinguished company thronged the rooms of)- the College of Physicians on Wednesday evening last, at thei, invitation of the President and Fellows, and enjoyed theh pleasures of a gossip agreeably cliversified by the inspection

of the numerous objects of scientific and general interest whichi were collected on the occasion. Amongst these the following

were conspicuous :-The portrait of Sir Thomas Watson, Bart.,e late President of the College, by Richmond. Specimens ofe sublimates of the alkaloids, of blood-stains, of arsenious acid_ and corrosive sublimate, &c., by Dr. Guy, with photographsof the same by Dr. Julius Pollock, Dr. Maddox, and Mr.

’

Ernest Edwards. Of these specimens it is to be noted thatthey represent in all probability a most important advance in

our means of detecting poisons. It has been found that bysublimation an exceedingly minute quantity (some thousandthst of a grain for instance) of an alkaloid will be deposited in a

- crystalline form, which is capable of recognition under ther microscope. Confirmatory evidence can be obtained by the; application of chemicals to the substance on the glass slide.

Nothing more interesting and valuable than Dr. Guy’s contri-. butions was to be seen in the rooms.; Microscopes and microscopic objects, drawings, photographs,: photo-micrographs, medical portraits, &c., were exhibited in

abundance by Messrs. Powell and Lealand, Browning, JamesHow, Murray and Heath, Ernest Edwards, and Bellamy;

, Messrs. Moira and Haigh exhibited fine photographs ofthe late Drs. Ferguson and Brinton. Specimens of drugsto illustrate the British Pharmacopoeia were shown by Pro-fessor Redwood; extra-pharmaceutical preparations by Messrs.Savory and Moore ; specimens of various alkaloids by

Messrs. Morson. A medical lantern for rhinoscopy andlaryngoscopy was shown by Dr. Thudichum. The light isadmirably white and steady. It is obtained apparently byexposing a portion of calcium to the flame of a lamp, throughwhich is passed a stream of oxygen gas. The action of sonorousvibrations on gaseous and liquid jets was illustrated in thesmall library, whence the shrillest whistling proceeded prettyconstantly throughout the evening. How is it, by the way,that Professor Tyndall’s name only was associated with thesephenomena in the programme, and that of Mr. Barrett, thefirst observer, not mentioned ?Vre noticed with pleasure a pair of exquisite photographs of

Louis Prince of Hesse, and the Princess Alice, with herchildren, which have been presented by her Royal Highness toSt. George’s Hospital "in remembrance of the satisfaction andgratification which yesterday’s visit to the hospital affordedher Royal Highness." Mr. W. Ladd exhibited several electricalmachines of remarkable power.

CHARING-CROSS HOSPITAL.

A PUBLIC distribution of prizes to students at the aboveschool took place on Friday, the 19th ult. The Right Hon.Sir Frederick Pollock presided, and, after passing in reviewthe origin and useful career of Charing-cross Hospital, urgingthat, from its position in the midst of a crowded neighbourhood,it had the strongest claims to support, proceeded to point outthe importance of promoting medical science, arguing that themedical profession was, even in the rudest state of society,one of the most useful of its elements, it being possible to
