I allude to the investigations of the Baron Freyherr von Reichenbach, published in Wohler and Liebig’s “Annals of Chemistry,” and already translated for the benefit of the English reader, and familiar to the reading public.

I take it for granted, Archy, that you have read the book I refer to, and that I have only to bring to your recollection two or three of the facts mentioned in it, bearing upon the present point.

Then you remember that Von Reichenbach has shown, that the two ends of a large crystal, moved along and near the surface of a limb, in certain sensitive subjects, produced decided but different sensations, one that of a draught of cool air, the other of a draught of warm air. That the proximity of the northward pole of a magnet again produces the former, of the southward pole the latter; of the negative wire of a voltaic pile, the former, of the positive wire, the latter; finally, that the two hands are equally and similarly efficient, the right acting like the negative influence, the left like the positive, of those above specified. Von Reichenbach came to the conclusion, from these and other experiments, that the two lateral halves of the human body have opposite relations to the influence, the existence of which he has proved, while he has in part developed its laws. And he throws out the very idea of a transverse polarity reigning in the animal frame. Do you remember, in confirmation of it, one of the most curious experiments which he leads Fräulein Maix to execute; valueless it might be thought if it stood alone, but joined with parallel effects produced on others, its weight is irresistible. Miss M. holds a bar magnet by its two ends. In any case it is sensibly inconvenient to her to do so. But when she holds the southward or positive pole of the magnet in her right hand, the northward or negative pole in her left, the thing is bearable. When, on the contrary, she reverses the position of the magnet, she immediately experiences the most distressing uneasiness, and the feeling as of an inward struggle in her arms, chest, and head. This ceases instantly on letting go the magnet.

I will not inflict upon you more of Von Reichenbach, though sorely tempted, so much is there in common between his Od and the influence investigated by the Count de Tristan. If you know the researches of the former already, why verbum sat; if not, I had better not attempt further to explain to you the ignotum per ignotum.

And in truth, with reference to the divining rod, I have already given my letter extension and detail enough for the purpose I contemplated, and I will add no more. I had no intention of writing you a scientific analysis of all that I believe to be really ascertained upon this curious subject. My wish was only to satisfy you that there is something in it. I have told you where you may find the principal collection of facts elating to it, should you wish further to study them; most likely you will not. The subject is yet in its first infancy. And what interest attaches to a new-born babe, except in the eyes of its parents and its nurse? I do not in the present instance affect even the latter relation. I am contented with exercising the office of registrar of the births of this and of two or three other as yet puling truths, the feeble voices of which have hitherto attracted no attention, amidst the din and roar of the bustling world. Hoping that I have not quite exhausted your patience, I remain, Dear Archy, yours faithfully.

Mac Davus.


HORÆ CATULLIANE.

LETTER TO EUSEBIUS.

My Dear Eusebius,—I have lately spent a few weeks with our old friend Gratian, at his delightful retreat in Devonshire, which he has planted, fenced, and cultivated, and made as much a part of himself in its every fit and aspect as his own easy coat. You see him in every thing, in the house and out of it. Cheerful, happy, kind, and best of men! Not an animal in his stall, or his homestead, but partakes of his temper. His horses neigh to you, his cows walk up to you, his pigs run to you, rather disappointed, for you have not his stick to rub their backs with. Rise in the early morning, when the dew is sparkling on the lawn, and his spaniel greets you, runs round and round you with a bark of joyous welcome; and even his cat will, as no other cat will, show you round the gravel walks. And thrice happy are all when their expected master appears, somewhat limping in his gait, (and how few, under his continual pain, would preserve his cheerfulness as he does!) Every creature looks up into his face as better than sunshine, and he forgets none. He has a good word for all, and often more than that in his pockets. The alms beggar, the Robin, is remembered and housed. There is his little freehold of wood raised some feet from the ground opposite the breakfast room window—an entrance both ways—there is he free to come and go, and always find a meal laid for him. Happy bird, he pays neither window-tax nor servant’s tax, and yet who enjoys more daylight, or is better served?
