I’ve managed to get the 1st edition (1885) of this interesting antiquarian book.

with Curious Anecdotes of Ladies Fond of Administering Birch Discipline.
Compiled by an Amateur Flagellant
London
Printed for Private Circulation
1885
In the 19th century, general-interest magazines became very popular. Usually there was a lot of space for letters to the editor where various topics were discussed, among them the question of corporal discipline: the pro’s, the contra’s, how & when to punish, what implements to use, and so on. Seems like in one magazine (The Englishwoman’s Domestic Journal) CP was discussed to a large extent, and Experiences of Flagellation features a really interesting selection of those letters. Of course readers used pseudonyms, and reading them I felt a bit like in a 21st century spanking forum or chatroom: “Pro-Rod”, “A Lover of Obedience”, “A Teacher of Troublesome Girls”, “A Rector”, “The husband of a Schoolmistress”, “An Old Boy”, “Miss C.”, and so on.
Here’s a passage from this book, by a 24 years old Lady who calls herself “Gratitude”. She’s telling about her experience in a “school for young ladies”:
“I own, as you see, one of the most honoured names in England, and call myself ‘Gratitude,’ because I am anxious to show my gratitude for the fact that I owe my present position as a useful happy English lady to the firm discipline I experienced at the very turningpoint of my life, I was brought up in a loving home, I had every possible advantage; but amidst it all I became sullen, self-willed, and disobedient and idle. I was the grief of my parents and a byword to my companions. However, soon after I was fifteen I most fortunately was sent to Mrs–––’s school for young Ladies, in Brighton, where I showed the same evil disposition which I had evinced elsewhere, but where, most fortunately and happily for me, it was checked and cured.
In school and out of it, during the first month, Mrs.— and the other teachers reproved me, wet me tasks, and ‘kept me in.’ But I only grew worse; and one night after I had refused to do an ‘imposition,’ as boys call a punishment lesson, Mrs.––– came and sat in my room after I was in bed and talked to me most impressively. The next day, however, the impression of what she had said wore off, and I was as bad as ever. But a change was at hand, for in the evening, when we had just gone to our bedrooms, Mrs.––– again came to me, and said, ‘Miss W., you will tonight occupy the dressing-room adjoining my room. I will show you the way.’ I was half inclined to disobey. However, I followed my governess through her bedroom and across a small sitting-room, which opened out of it into a room comfortably furnished, in which was a small low bed, and telling me to undress and go to bed, Mrs.––– left me, locking the door after her. I had been in bed about a quarter of an hour when Mrs. came to me, holding in her hand a long birch-rod. Placing the candlestick and the rod an the table, she told me that but one course was now open to her after my behaviour, and that she was going to flog me, and I was to get up. But though the twigs of the birch-rod stood out in ominous shadow in front of the candlestick, and while I noted the thin, closely wrapped handle of that rod, and its fanlike-spreading top, I never attempted to obey. Three times Mrs––– told me to get up, but I stirred not. She then very deliberately turned down the bedclothes, and again told me to get out of bed. I began to feel that I was going to be conquered, but I stirred not. Mrs––– returned to her own room, and came back with a small, thin riding-whip, and said, ‘must I use this?’
There was something about her which quite awed me – it was more her manner than her tall powerful figure – and as she swung that whip about in her hand I at once stepped out of bed and stand before her. ‘Give me your hands,’ she said, but I put them behind me, when slash across my shoulders came six or seven smart strokes of her whip, and screaming I put out my hands, which she fastened together with a cord by the wrists. Then making me lie down across the foot of the bed face downwards, she very quietly and deliberately, putting her left hand round my waist, gave me a shower of smart slaps with her open right hand – a proceeding which so surprised and humiliated my proud self that I could hardly believe in my own identity, and as I screamed and struggled, she merely said, ‘This is for not doing now as I told you, and it will not only punish you for that, but will increase the pain of the birching I am now going to give you.’ Mrs. ––– then, as I lay, spoke to me for a few minutes with great kindness and earnestness. She then rose, took the birch in her right hand, and stooping over me, pressed her left hand tightly on my shoulder so as to hold me as if I were in a vice; then raising the birch, I could hear it whizz in the air, and oh, how terrible it felt as it came down, and as its repeated strokes came swish, swish, swish, on me! yet I felt, spite of the terrible stinging pain, that I deserved it all – and it was painful. I was a stout fair girl, and very sensitive to pain. I screamed, I protested, I implored, but it was of no avail; Mrs. ––– heeded not my cries, but held me down and birched on till she had finished a whipping which seemed to have lasted an age, but which quite changed my character.
At last it was over. I was permitted to rise, my hands were unbound, and, burning and smarting, I raised my tear-stained face to my true friend’s, on whose face no sign was visible, of the slightest anger or passion. Calm and serene, she wished me ‘Good-night’ and left me conquered. Henceforward I was a different girl; and though a few weeks afterwards, I relapsed, yet another night spent in Mrs.–––’s dressing-room and another similar application by her of that wonder working birch – I did exactly as she told me this time – sufficed finally to cure me. I became cheerful, obedient, unselfish. My parents and friends the next holidays could hardly believe that I was the same girl. I stayed three years with Mrs.––– at Brighton, leaving her when I was nineteen with much regret. I am now twenty-four, and hope to be married at Easter to the best man in the world who never could have loved me had not sensible, wholesome discipline changed my evil nature, as the means under Higher Power of doing so. I am thankful to publish my experience, and so to express not only my gratitude, but confirm what others have so well said and told on this subject.”

The whole book has 80 pages and ends with a poem by George Coleman (from The Rodiad) whose last two verses I shall quote here:
Shall I complain? When better hope is passed,
FLOG and be flogged - is no bad fate at last.
