The well-known Roman physician, Dr. C. Liberali, M.D., in his "Hygienic Medical Hand-book for Travellers in Italy," says:--"The climate of Rome is in the highest degree salubrious and favourable to all, but especially to delicate persons; but they should follow the advice of a skilful physician of the country." People rush through Europe at express rate, eat all sorts of things that they are unused to at unusual hours, over-exert themselves, change the whole course of the living to which they have been accustomed, get ill, and then say, "It's the climate of Rome." There is no doubt that malaria fever does exist in the neighbourhood of Rome, but only during the three hot months; and as there are no visitors at Rome then, they are not likely to get it. It does not walk about the streets seeking whom it may devour, as some people suppose. The fever visitors get is ague fever, like that known in the Fen districts, and this is invariably taken through imprudence. USEFUL HINTS. Avoid bad odours. Do not ride in an open carriage at night. Take lunch in the middle of the day. This is essential. It is better to take a light breakfast and lunch, than a heavy breakfast and no lunch. No city in the world is so well supplied with good drinking water as Rome. The best is the Trevi water. Do _not_ drink Aqua Marcia; it is too cold. If out about sunset, throw an extra wrap or coat on, to avoid the sudden change in the atmosphere. There is no danger beyond being apt to take a cold. Colds are the root of all evil at Rome. Do not sit about the ruins at night. It may be very romantic, but it is very unwise. There is no harm in walking. Close your windows at night. If you get into a heat, do not go into the shade or into a building till you have cooled down. Do not over-fatigue yourself. Follow these hints, and you will avoid that great bugbear, Roman fever. "A hint on the spot is worth a cart-load of recollections."--GRAY. THE TIBER. The work of clearing the bed of the Tiber has at last commenced. It is proposed to clear away the accumulation of the mud at different parts, remove some of the old masonry that stands in the bed of the river, and widen it at certain points. We very much doubt if this will have any effect upon the floods, as during the republic and empire, when there was not all this accumulation, Rome was flooded several times. The valley of the Tiber, in which Rome stands, is very low, forming, as it were, a basin which is easily overflowed. It would be advisable if the authorities were to clean out the old drains, and put swing trap-doors over their mouths, so that the drainage might flow out, and the river prevented from flowing in. Every winter some part of the city is under water, which is caused by the river rushing up the drains into the city, and not by the overflow of the Tiber. This inpouring might easily be stopped.
