308 DETAILED SYNTHESIS. 



841. AT THE INNER ANGLE OF THE EYE is a Small 



red eminence enclosing a cluster of sebaceous glands, 

 and furnished with minute hairs. Sometimes they grow 

 out and are troublesome ; they are then merely to be 

 extracted. The fleshy part sometimes extends over the 

 cornea ; if it obscures vision or is troublesome, it should, 

 as it can very easily, be removed. 



842. COLDS, WINDS, AND DUST annoy the eye, and 

 may cause inflammation. From the latter it can be pro- 

 tected ; the former should be avoided. 



843. THE EYE is SOMETIMES PERMANENTLY TURNED 

 inward (cross-eyed), or outward (wall-eyed) ; usually 

 because it is weak, or in some respect imperfect. 



844. Remark. If the imperfection is outgrown, and yet the direc- 

 tion of the eye not corrected, as is sometimes the case, the operation of 

 cutting one of the muscles may be tried, with the expectation of a favor- 

 able result ; but if the weakness of the eye continues, the operation will 

 be worse than useless. 



845. THE EYE is A COMPOUND ORGAN: the eye 

 proper is constructed of sinewy, secretory, muscular, and 

 nervous tissues, and in its accessories gristly and bony 

 are also found. 



846. Remark. Thus in STRUCTURE, in MODE OP ACTION, in the 

 CAUSES THAT EXCITE IT, and THEIR REGULATION, and in all that is neces- 

 sary to the preservation of the eye, there is a remarkable simplicity that 

 cannot fail to excite admiration and enlist the attentive study of so im- 

 portant an organ. Some other exceedingly interesting facts will be pre- 

 sented, when it is, with other organs, made up into the apparatus of 

 sight. 







TJie Ear. 



847. THE EAR is one of the most delightsome and 

 precious as well as useful of the organs of sense, for it is 

 not only attuned to all the sweet and varied music of 

 nature, but, properly cultivated, it enraptures the mind 

 with the marvellous productions of art. No other organ
