MEDICAL ODDS AND ENDS. My dear friends,--We are going to ring in now, and end our course. I will be sorry and glad, and you will be the same. We are this about everything. It is the proportion that settles it. I am, upon the whole, as we say, sorry, and I dare say on the whole you are not glad. I dislike parting with anything or anybody I like, for it is ten to one if we meet again. My text is, "_That His way may he known upon earth; His saving health to all nations._" You will find it in that perfect little Psalm, the 67th. But before taking it up, I will, as my dear father used to say,--you all remember him, his keen eye and voice; his white hair, and his grave, earnest, penetrating look; and you should remember and possess his Canongate Sermon to you,--"The Bible, what it is, what it does, and what it deserves,"--well, he used to say, let us _recapitulate_ a little. It is a long and rather kittle word, but it is the only one that we have. He made it longer, but not less alive, by turning it into "a few recapitulatory remarks." What ground then have we travelled over? _First_, our duties to and about the Doctor; to call him in time, to trust him, to obey him, to be grateful to, and to pay him with our money and our hearts and our good word, if we have all these; if we have not the first, with twice as much of the others. _Second_, the Doctor's duties to us. He should be able and willing to cure us. That is what he is there for. He should be sincere, attentive, and tender to us, keeping his time and our secrets. We must tell him all we know about our ailments and their causes, and he must tell us all that is good for us to know, and no more. _Third_, your duties to your children; to the wee Willie Winkies and the little wifies that come toddlin' hame. It is your duty to _mind_ them. It is a capital Scotch use of this word: they are to be in your mind; you are to exercise your understanding about them; to give them simple food; to keep goodies and trash, and raw pears and whiskey, away from their tender mouths and stomachs; to give them that never-ending meal of good air, night and day, which is truly food and fire to them and you; to _be_ good before as well as to them, to speak and require the truth in love,--that is a wonderful expression, isn't it?--the truth in love; that, if acted on by us all, would bring the millennium next week; to be plain and homely with them, never _spaining_ their minds from you. You are all sorry, you mothers, when you have to spain their mouths; it is a dreadful business that to both parties; but there is a spaining of the affections still more dreadful, and that need never be, no, never, neither in this world nor in that which is to come. Dr. Waugh, of London, used to say to bereaved mothers, Rachels weeping for their children, and refusing to be comforted, for that simplest of all reasons, because they were not, after giving them God's words of
