scale of the marvellous; the feats of Aladdin are tame and dull, and the slaves of the lamp yield precedence to the spirits which preside over the battery and the boiler. Of all the physical agents discovered by modern scientific research, the most fertile in its subserviency to the arts of life is, incontestibly, electricity; and of all the applications of this subtle agent, that which is transcendently the most admirable in its effects, the most astonishing in its results, and the most important in its influence upon the social relations of mankind, and upon the spread of civilisation and the diffusion of knowledge, is the electric telegraph. No force of habit, however long continued, no degree of familiarity, can efface the sense of wonder which the effects of this most marvellous application of science excites. Being at Paris some years ago, I was engaged to share with M. Leverrier, the celebrated astronomer, and some other men of science, in the superintendence of a series of experiments to be made before committees of the Legislative Assembly and of the Institute, with the view of testing the efficiency of certain telegraphic apparatus. On that occasion, operating in a room at the Ministry of the Interior, appropriated to the telegraphs, into which wires proceeding from various parts of France were brought, we dictated a message, consisting of about forty words, addressed to one of the clerks at the railway station at Valenciennes, a distance of 168 miles from Paris. This message was transmitted in two minutes and a-half. An interval of about five minutes elapsed, during which, as it afterwards appeared, the clerk to whom the message was addressed was sent for. At the expiration of this interval the telegraph began to express the answer, which, consisting of about thirty-five words, was delivered and written out by the agent at the desk, in our presence, in two minutes. Thus, forty words were sent 168 miles, and thirty-five words returned from the same distance in the short space of four minutes and thirty seconds. But, surprising as this was, we soon afterwards witnessed in the same room a still more marvellous performance. The following experiment was prepared and performed at the suggestion and under the direction of M. Leverrier and myself: Two wires, extending from the room in which we operated to Lille, were united at the latter place, so as to form one continuous wire extending to Lille and back, making a total distance of 336 miles. This, however, not being deemed sufficient for the purpose, several coils of wire wrapped with silk were obtained, measuring in their total length 746 miles, and were joined to the extremity of the wire returning from Lille, thus making one continuous wire measuring 1082 miles. message consisting of 282 words was then transmitted from one A end of the wire. A pen attached to the other end immediately began to write the message on a sheet of paper moved under it by a simple mechanism, and the entire message was written in full in the presence of the committee, each word being spelled completely and without abridgment, in fifty-two seconds, being at the average rate of five words and four-tenths per second! By this instrument, therefore, it is practicable to transmit intelligence to a distance of upwards of 1000 miles, at the rate of 19,500 words per hour! The instrument would, therefore, transmit to a distance of 1000 miles, in the space of an hour, the contents of about forty pages of the book now in the hands of the reader! But it must not be imagined because we have here produced an example of the transmission of a despatch to a distance of 1000 miles, that any augmentation of that distance could cause any delay of practical importance. Although the velocity of the electric current has not been very exactly measured, it has been established beyond all doubt that it is so great that to pass from any one point on the surface of the earth to any other, it would take no more than an inappreciable fraction of a second. If, therefore, the despatch had been sent to a distance of 20,000 miles instead of 1000, its transmission would still have been instantaneous. Such a despatch would fly many times round the earth between the two beats of a common clock, and would be written in full at the place of its destination more rapidly than it could be repeated by word of mouth. When such statements are made, do we not feel disposed to exclaim 'Are such things here as we do speak about? Or have we eaten of the insane root That makes the reason prisoner?' In its wildest flights the most exalted imagination would not have dared, even in fiction, to give utterance to these stubborn realities. Shakspeare only ventured to make his fairy 'Put a girdle round the earth in forty minutes.' To have encircled it several times in a second, would have seemed too monstrous even for Robin Goodfellow.* SIMPLE PROPORTION.

The statement of the Minister of Finance in Calcutta was telegraphed to England on Friday, April 7th, 1865. The newspapers in England were thus able to comment upon this statement two days after its delivery, more than 5000 miles away; and, of course, it would have arrived in a few minutes but for unavoidable delays at various stations in course of transmission.-EDS.
