the above date said: "You must not say that a man died of such and such a disease, but of so many physicians, surgeons and apothecaries'?

The most pungent and most witty definition of the doctor's character probably is that given, I think, by Talleyrand. When Napoleon, in a fit of despondency, said that he would forsake war and turn physician, the sarcastic courtier said sotto voce: Toujours assassin ?`

THE LOST RIVERS OF LONDON.

LONDON is deficient in two conditions to render it

picturesque it lacks diversity of surface, and it

lacks water. In so vast an expanse of ground as is covered by London, Ludgate Hill and Notting Hill are mere molehills.* As to water, it has the Thames, but that is accessible at short and broken intervals only. There is the Embankment from Blackfriars to Westminster; a short bit at Chelsea, and the Albert Embankment. But the City people during the day have. no time to waste on their Embankment, and in the evening they are gone to the suburbs, and so this grand promenade is given up to occasional country cousins'

The highest point north is Hampstead Hill, 400 feet above sea-level; to the south Sydenham Hill, 365 feet; Primrose Hill, about 260 feet; Herne Hill, about 180 feet; Denmark, about 100 feet; Orme Square, 95 feet; Broad Walk, 90 feet; North Audley Street, 83 feet; Tottenham Court Road, 85 feet; Regent Circus, 90 feet; Cornhill, 60 feet; Charing Cross, 24 feet; Euston Road, 90 feet; Cheapside, 59 feet; Farringdon Street, 28 feet; St. Katherine's, Regent's Park, 120 feet; Camberwell Green, 19 feet.

visits, and to permanent ruffianism. For, of course, no one from the more northern parts of London ever thinks of coming so far to take a stroll on that Embankment, from which nothing is to be seen but mud-banks in the near prospect, as by a perverse arrangement of nature it is generally low water when you want to take a walk; on the opposite bank only dismal wharves present themselves. As to the Chelsea Embankment, that is patronized by the dwellers in that region only, if they do not neglect it altogether, as people generally do who live in a rather picturesque locality. The less we say about the Albert Embankment the better; its characteristics are dingy hovels and smoke-belching pottery chimneys on one side, smoke and cinders from passing steam-barges and penny steamers on the river, and a dreary outlook on the opposite side, scarcely relieved by the Tate Gallery, which, for reasons unknown to the general public, but self-evident to those who can see the wire-pulling behind, has been pitched, like a King Log, into the Pimlico swamp. All other parts of the river are inaccessible to the public, and therefore as good as non-existent for the Londoner.

Thus much for the Thames. As to other pieces of water to be found in public parks, they are mere ponds, and of benefit only locally. As to public fountains, which form the peculiar charm of so many Continental cities, where the melodious splash of water is heard day and night, London possesses none. True, there are two squirts in Trafalgar Square, and the Shaftesbury fountain is making asthmatic efforts to assert itself, whilst the Angel at the top seems to be shooting Folly as it flies all around him in the savoury purlieus of the

Haymarket. The small drinking fountains found here and there are evidences of philanthropy, which may be grateful to children and tramps, to horses and dogs, but do not add much to the aquatic features of London. There are canals, it is true, but they are private property, and so fenced, hoarded, and walled in, as to be of no use to the public. And as a rule their water is so dirty that no one with a nose would walk by the side of them, even if allowed to do so.

But London was not always so deadly level and so waterless as it is now. In ancient days there were high hills and deep valleys in the very heart of it. From the river Lea to the river Brent on the northern side of London there were numerous rivulets and brooks descending from the northern heights through the City and its western outskirts into the Thames, brooks and rivulets which at times assumed such dimensions as to cause serious inundations. It was the same in the south of London, where from the Ravensbourne to the Wandle similar watercourses reached the Thames from the southern hills.

All those brooks between the four rivers we have named, and which alone are still existing, have totally disappeared. What were their features, when they still flowed from northern and southern heights, and what were the causes and the process of their disappearance, we now intend to investigate, by proceeding from east to west, and taking the northern shore of the Thames first.

The site on which the Romans founded London was the rising ground on the northern bank of the Thames, from the present Fish Street Hill, or Billingsgate, to

the Wallbrook. At a later date of their occupation they extended the City eastward to the Tower, and westward to the valley of the Fleet. Then the valley of the Wallbrook divided the City into two portions of almost equal size. To the north the buildings extended to the present Aldgate and to Moorfields, and westward to Newgate and Ludgate. The wall which encompassed the town began at the Tower, and in a line with various bends in it terminated at the Arx Palatina, somewhere near the present Times office. On the east of the town, where the country was flat, there was a marsh, extending to the river Lea. To the north-west were dense forests stretching far into Middlesex, and abounding with deer, wild boar, and other savage animals. This forest was partly the cause of the many brooks, which in those days watered London from the northern heights; it being a well-known fact that trees absorb and retain moisture.

It is doubtful whether there were any Roman buildings west of the Fleet; Fleet Street and the Strand certainly were then undreamt of, and did not come into existence till centuries after the Romans had left our island. To the west of the present Strand, the ground lying very low, it was frequently inundated by the river, and there are persons still living who can remember Belgravia and Pimlico as a dismal swamp. Westminster Abbey stood on an island, which rose above the marshy environs, and even as late as the times of Charles II. occasional high tides converted the palace of Whitehall into an island.

The great forest of Middlesex above mentioned came close to the City wall; it had, in fact, occupied a
