Expletives are words not needed for the sense, but used merely 

 to fill up and round off the sentence. Of course expletives are 

 to be avoided : 



" While expletives their feeble aid do join, 

 And ten low words oft creep in one dull line." Pope. 



The term depone, in law phraseology, is used by the Scotch 

 where we use depose. The distinction is arbitrary, for we speak 



of the deponent while we *ay he depotet, not deponti t though of 

 old deponet was tued in England : 



" And further Bprot deponeth," etc. -" .Slate Trial*." 



The retina, or eye-net, the immediate teat or rather instru- 

 ment of Twion, in the net-like expansion of the optic netre, on 

 which object* are drawn, and from which they are made ruible 

 by the mind. 



Reticulated denotes that which w made like net-work. Henoe 

 tho meaning of reticule or little bag made of net-work, Home time 

 since much in use among ladiea. 



To ruminate in to pass and repass the food through the rumen 

 or rju.Uet in order to ita repeated chewing. Hence the phrase to 

 chew the cud. Metaphorically, to ruminate u to muae, to reflect 

 calmly : 



" Aa when a traveller, a long day put, 

 In painful search of what he cannot find, 

 At night's approach, content with the next cot, 

 There ruminates awhile his labour lost." 



In prose we say to ruminate on, that is, to meditate upon : 



" He practises a slow meditation, and ruminate* on the subject." 

 Watts, " On the Mind." 



Bankrupt, a term of French extraction, properly denotes a 

 trader or money-dealer whose bank or bench is broken, the last 

 condition of commercial destitution : 



" A bankrupt is defined a trader who secretes himself, or doea certain 

 other acts tending to defraud his creditors." Blockstone. 



The terms rustic and rural differ in their application, the first 

 being said of persons, the second of things. Rustics are often 

 insensible to the loveliness of rural scenes. 



COMPOSITION.

 tions : 



TFords. F. R. 



Confide in, fldo, I trust.

Congenial with, genus, kind. 



Congratulate on, gratulor, I congratulate 



Connect with, necto, I bind.

Consecrate to, sacer, sacred.

Care of, cura, care. 



To consist of, to consist in, and to consist u-ith, have each 

 different meaning. To consist of has reference to the materials 

 of which an object is made up ; to consist tn has reference to 

 the substance or essence of a thought ; to consist with has 

 reference to the character or dignity of an agent or actor. It 

 consists mth the character of a wise man to expound doctrines 

 in which the welfare of bis fellow-men consists : that exposition 

 he makes by words which consist of sounds, or by books which 

 consist of letters. The wealth of a nation consists not so much 

 in, the number as the heart, the intelligence, and the sinews of 

 its inhabitants.
