able on wider lines than have yet 

 been attempted in Infant Welfare 

 Centres throughout the country. 



Modern science lays great stress 

 on the breast-feeding of infants and 

 on the methods of improving the 

 health and general condition of the 

 mother, in cases where natural 

 feeding might otherwise have to 

 be abandoned owing to abnormal 

 conditions. In cases where the 

 child cannot be naturally fed, 

 rules are laid down for the prepara- 

 tion of food which shall as nearly 

 as possible conform to natural food, 

 and shall provide the vitamines 

 which are essential to the health 

 and growth of all children, espe- 

 cially in the early months of in- 

 fancy. For the endowment of 

 motherhood, a course frequently 

 advocated by social reformers, a 

 definite scheme has been proposed 

 in New South Wales to cost 

 1,600,000 a year. See Child Wel-

Mother-of-Pearl. Inner coat- 

 ing of shells of many bivalve mol- 

 luscs, including pearl oysters. It 

 possesses some resemblance to 

 pearls, and has much the same com- 

 position. On account of its beau- 

 tiful iridescence and its high polish, 

 mother-of-pearl is largely used in 

 thin sheets to decorate articles of 

 ornament and for the toilet, 

 knife handles, and minor pieces of 

 jewelry. Though mostly derived 

 from the seas of the torrid zones, a 

 good variety is obtained from 

 Mediterranean pearl mussels.

 lar name applied equally to Saxi- 

 fraga sarmentosa and Linaria cym- 

 balaria. The first named, also 

 known as creeping sailor and wan-

 flowers are white with a few spots 

 of yellow and red. Linaria cymba- 

 laria is a much smaller plant,

 Wishaw, a police burg, the two 

 having been united in 1920 

 Motherwell lies N.E. of the river 

 Clyde, which it touches on the 

 S.W., 13 m. from 

 Glasgow and 2 m. 

 from Hamilton, 

 and is served by 

 the Cal. Rly. It 

 owes its growth to 

 its situation on 

 the great coal- 



field ; in addition

 boilers and bridges being among its 

 products. The public buildings in-

Motherwort (Leonurus car- 

 diaca) Perennial herb of the 

 natural order Labiatae. A native 

 of Europe and N. and W. Asia, it 

 has a stout rootstock, and erect, 

 four- angled, leafy stems. The op- 

 posite leaves are deeply cut into 

 five- or seven lobes, and the rosy- 

 pink flowers are arranged in a 

 series of whorls, which convert the 

 upper part of the stem into a long 

 leafy flower-spike. The whole 

 plant is downy. 



Moth Orchid (Phalaenopsis). 

 Genus of epiphytes of the natural 

 order Orchidaceae, natives of the 

 Malay Archipelago and Eastern 

 India. They have no pseudo-bulbs, 

 but have permanent short leafy 

 stems, and the broad leathery 

 leaves are in two ranks. The large

 Hamilton, founded on Ouida's 

 novel of the same name, and pro- 

 duced, March 25, 1882, at the 

 Globe Theatre, London. 



Motion (Lat. motio). In me- 

 chanics, change of position of a 

 body. All motion is relative, e.g. a 

 body moving on the earth is treated 

 usually as though the earth were at 

 rest, though it is moving round 

 the sun, and the latter is moving 

 through space, both of which 

 motions are imparted to the 

 moving body. 



TJIE LAWS OF MOTION. Motion 

 is governed by three laws first 

 enunciated by Newton. They de- 

 fine the effect of external force on 

 the motions of bodies, and may be 

 stated as follows : (!) Every body 

 continues in its state of rest or of 

 uniform motion in a straight line, 

 unless it is compelled by an im- 

 pressed force to change that state. 

 (2) Change of motion is propor- 

 tional to the impressed force and 

 takes place in the direction of the
