PRACTICAL PHYSIOLOGY;

A SCHOOL MANUAL OF HEALTH:

Being an Introduction to the Elementary Principles of Physiology, and a Practical Guide to the means of securing Health and Life. Intended for the use of classes and for general reading. By EDWIN LANKESTER, M.D., LL.D., F.R.S., late Lecturer on Physiology, St. George's School of Medicine, London; late Superintendent of the Government Food Museum, South Kensington; and Medical Officer of Health, St. James's, Westminster. Fifth edition, with

numerous Illustrations and Questions for Examination, Tables, and Glossary.

The object of this work is to supply information on the subject of the structure and functions of the human body to boys and girls between the ages of ten and fifteen years. It is written in such a manner that intelligent teachers may instruct their pupils in the great facts on which life and health depend. It is found, practically, that a large amount of death and disease occur in the community from the ignorance which exists of the simplest facts with regard to the structure of the human body, and the nature of those functions on which healthy life depends. 'I have no hesitation in saying it is just what we require. I know of nothing which contains anything like the same amount of practical (elementary) information in the same compass; and it is written in so simple and easy a style that the knowledge it conveys will be more readily assimilated and utilised.'-Dr. Rumsey.

RUPTURES (By Royal Letters Patent).

WHITE'S MOC-MAIN LEVER TRUSS,

Perfected and Exhibited in the Great Exhibitions, 1851 & 1862, IS allowed by upwards of 500 Medical Gentlemen to be the most effective invention in the curative treatment of HERNIA. The use of a steel spring, so often hurtful in its effects, is here avoided; a soft bandage being worn round the body, while the requisite resisting power is supplied by the MOC-MAIN PAD AND PATENT LEVER, fitting with so much ease and closeness that it cannot be detected, and may be worn during sleep. A descriptive circular may be had, and the Truss (which cannot fail to fit) forwarded by post, on the circumference of the body (two inches below the hips) being sent to the

LAMPLOUGH'S

PYRETIC SALINE

'HAS MORE THAN A EUROPEAN REPUTATION,' And is important to all, more especially those who have charge of others, to Travellers, English Ministers, British Consuls, and Europeans seeking to reside in Tropical and Foreign Climates.

It is found pre-eminently beneficial in preventing and curing SMALLPOX, by Purifying, Invigorating, and Vitalising the Blood. Any person who has already this complaint should take it, and be kept in a cool and darkened room, to prevent its leaving any trace on the features.

'It cures the worst form of ordinary or Sick Headache in ten minutes.' Taken as a morning or evening draught it is most agreeable, invigorating, and cooling; it removes bilious affections, heartburn, and acid eructations, in a marvellous manner.

Her Majesty's Representative, the Governor of Sierra Leone, in a Letter of Request for an additional supply of the PYRETIC SALINE, states: It is of GREAT VALUE, and I shall rejoice to hear it is in the hands of all Europeans visiting the Tropics.'

SICKNESS, HEADACHE, and NAUSEA are in most cases immediately relieved by taking a teaspoonful in a tumbler of cold water. This can be repeated once or twice in two hours, if needful.

SEA VOYAGES.-It is a very valuable accompaniment, and should on no account be omitted. It instantly allays the sea or bilious sickness.

For BILIOUS CONSTITUTIONS, giving rise to vitiated secretions, Indigestion, and Eruptions on the Skin, a teaspoonful should be taken daily with the dinner in a tumbler of water, and the same quantity on going to bed. A spurious Preparation having been palmed upon the Public, it is needful to notice the Trade Mark on the top right and left-hand corners of the Wrappers.

RAWAL PINDEE, PUNJAB, INDIA, 28th March 1871. On the recommendation of several officers who had some of your Pyretic Saline in the West Indies, all of whom speak in the highest terms of it, we were induced to try it for the first time in this Province. This result was not due to any novelty in Introducing a new medicine, but solely from the ascertained merits of your preparation after use in the fever-stricken districts by which we are surrounded, and we firmly believe that the use of your Pyretic Saline will do more to PREVENT fever than all the Quinine ever imported can cure. We write thus strongly, because, both from personal experience and cbservation, we believe we have at length found a remedy against the ever-present fevers of these parts, which costs the British nation hundreds of valuable lires in Peshawur alone. • We are now willing to enter into special terms for large and continued supplies, &c.'
