The conduct of medical students on botanical excursions generally appears in various phases. Some real lovers of the study, pale men in spectacles, who wear shoes and can walk for ever, collect every weed they drop upon, to which they assign a most extraordinary name, and display it at their lodgings upon cartridge paper, with penny pieces to keep the leaves in their places as they dry. Others limit their collections to stinging-nettles, which they slyly insert into their companions' pockets, or long bulrushes, which they tuck under the collars of their coats; and the remainder turn into the first house of public entertainment they arrive at on emerging from the smoke of London to the rural districts, and remain all day absorbed in the mysteries of ground billiards and knock-'em-downs, their principal vegetable studies being confined to lettuces, spring onions, and water-cresses. But all this is very proper--we mean the botanical part of the story--for the knowledge of the natural class and order of a buttercup must be of the greatest service to a practitioner in after-life in treating a case of typhus fever or ruptured blood-vessel. At some of the Continental Hospitals, the pupil's time is wasted at the bedside of the patient, from which he can only get practical information. How much better is the primrose-investigating _curriculum_ of study observed at our own medical schools! * * * * * SOME THINGS TO WHICH THE IRISH WOULD NOT SWEAR. MR. GROVE.--This insufferably ignorant, and, therefore, insolent magisterial cur, who has recently made himself an object of unenviable notoriety, by asserting that "the Irish would swear anything," has shown himself to be as stupid as he is malignant. Would, for instance, the most hard-mouthed Irishman in existence venture to swear that-- Mr. Grove is a gentleman; or that-- Sir Francis Burdett has brought honour to his grey hairs; or that-- Colonel Sibthorp has more brains than beard; or that-- Sir Robert Peel feels for anybody but himself; or that-- Peter Borthwick was listened to with attention; or that-- Sir Peter Laurie's wisdom cannot be estimated; or that-- Sir Edward George Erle Lytton Bulwer thinks very small beer of himself; or that-- The Earl of Coventry carries a vast deal of sense under his hat; or that-- Mr. Roebuck is the pet of the _Times_; or, in short, that-- The Tories are the best and most popular governors that England ever had. If "the Irish would swear" to the above, we confess they "would swear anything." * * * * * COMING EVENTS CAST THEIR SHADOWS BEFORE THEM. SIR JAMES CLARK is in daily attendance at the Palace. We suppose that he is looking out for a new berth under Government. * * * * * HOSTILITIES IN PRIVATE LIFE.
