ally
the slavery ends only in death.

_LAUDANUM AND MORPHINE._--These soothe pain and cause sleep; but beware of
them; they are made from opium, and like it, though more slowly, hurt mind
and body.

Beware also of _chloral hydrate_ and _chloroform_, which physicians give to
ease suffering and produce sleep. _Endure pain_ rather than form the habit
of using these narcotics.

_HASHISH, ETC._--This is prepared from the hemp plant growing in hot
countries, and is a terribly exciting poison.

The _areca nut_, the seed from a kind of palm, pear-shaped, and resembling
a nutmeg, is mixed with quick-lime and wrapped in a betel-leaf, which grows
on a vine belonging to the pepper family. This mixture reddens the saliva
and lips, and blackens the teeth. It is chewed by millions of people in
India.

The leaves of the _coca_, also of the _thorn apple_, are smoked or chewed
by the South American Indian.

ALL these poisons mean the same thing,--

_A little pleasure_, DISEASE, and DEATH.

Practical Work in the School-Room.

BY SARAH F. BUCKELEW & MARGARET W. LEWIS.

Part I.--THE HUMAN BODY.

TEACHERS' EDITION.

A TRANSCRIPT OF LESSONS GIVEN IN THE PRIMARY DEPARTMENT OF GRAMMAR SCHOOL
NO. 49, NEW YORK CITY.

This work was prepared especially to aid Teachers in giving oral
instructions in Physiology to Primary and Intermediate Classes. It is,
perhaps, the only Physiology published that is suitable for these grades.
Considerable attention is paid to the subject of Alcohol and Narcotics.

"First is given _a model lesson_; second, _a formula_, embodying the
principal facts given during the development and teaching; third,
_questions for the formula_; fourth, _directions for teaching_; and
fifth, _questions on the lesson_. These last are important. A full plan
of lessons is given for each week for five months, in each of six
grades, showing exactly how much work ought to be attempted. No book
could be made more helpful to teachers. To the thousands who are
asking, 'Tell us how to teach,' here are full, minute, and correct
instructions. Even the answers expected are given, blackboard outlines
are arranged, and nothing is wanting to make the book as useful to
teachers as it is possible for any book to be. It ought to have a large
sale. No book published during the last ten years will do more to drive
away routine from the school
