Gold, Silver, Platina, &c. Jane. I hope', Ma'. you will not forget to tell us something about gold' and silver
Ma. You mean', I suppose', to have me speak of the metals in general. I must begin by observing that metals are distinguished from all other substances, by four distinct qualities'; weight', opacity', and brilliancy', and the property of conducting the electric fluid or lightning ?
Mary. I expect I know', Ma'. what you mean'; you refer to the long rods of iron which are set up by the side of buildings to protect them from lightning!
Ma. I do' my child'; and since you have been so apt, it will give me pleasure to inform you that the lighining rod', is a discovery of the seventeenth century, by our esteemed countryman, Dr. Benjamin Franklin'.
Jane. But, Na', now for the metals'; you said they were heavy', opaque', and brilliant's
Ma. Yes'; and they have some other properties'; all of which contribute to render them greatly useful for the purposes of common life', and the different arts'. Gold, silver, and platina', are called roble metals'; becanse they cannot be altered by fire' or air. Platina is the heaviest metal known'; it is 23 times the weight of pure water'; gold is 19 times, quick silver, 109 times', lead 113 times', and silver, 10. times the weight of water'.
Mary. Where are the metals found', Mamma?
Ma. The noble metals are most abundant in America'; iron is found in almost every part of the world'; and lead', tin', &c. are very abundant both in Europe and America'. .
Addition. Note. When whole numbers and decimal parts, are expressed in the same sum, it is called a mixed number, as, 6.4, 15.14, 18.114. All the figures to the right of the point, must be regarded as decimal parts of uity, each of which has Sits absolute value, and its relative value. In the first sum, the 4, is four tenths of one; in the second, the 15, is the fifteen hundredths of one, or the five tenths of the one tenth; and in the third, the 114, is the one hundred and fourteen thoa sandth parts of unity.
Rule. 1. Place the given numbers, whether mixed or pure fractions, so that those of the same value shall stand immediatoly under each other.
2. Find the amount of each column, as in addition of whole numbers, observing to carry one for each ten, from a lower to a higher column.
3. Point off to the right of the sum, as many places for decimals, as equal the greatest number of decimal places in any of the given terms. The Proof is the same as in addition of whole numbers: Thus: (1) .4 (2) .702 (3) 3.52 .16 .673
DECIMAL FRACTIONS.--LESSON 31. .
Subtraction. RULE. 1. Place the lesser number under the greater, agreeably to their respective value.
2. Subtract as in whole numbers, and point off to the right, as directed in the addition of Decimal Fractions.
3. Proof, as in the Subtraction of whole numbers. Thus: (1).17236-.09937=07399, Ans. & .073997.09837 · =.17236, proof.
(2) 18.314671--1.9008= (3) 163.142-99.009=
Imperative Mood. The imperative form of the verb, expresses a command, directed always to the second person, and that person is invariably the subject of the verb; though generally understood. This verb is always in the present time, and agrees with the pronoun, you, in familiar language, and with thou or ye in the solemn and postic styles. Do, is the only helping verb that can associate with the verb in this mood; As: My son, give me your heart; or, my son, do you give your heart to me.
In this example, give, is an irregular transitive verb, imperative inood, present time, and agrees with its subject, you, in the second person, singular; Rule 1.
Go to the desert, my son, observe the young stork. Honour your father and mother. Love your brothers and sisters. Do your duty child, come and read. Simon, lovest thou me? Feed my lambs. Come ye to the help of the Lord. Do you help the poor, and needy.
Note. This mood expresses, not only a command, but entreaty, request, praycr, petition, desire, supplication, &c.
