press will answer the purpose. Such herbs as are oleaginous, must not be further compressed, when the oil begins to shew itself upon the paper. These herbs may then be conveyed to any distance, as from America to Europe, for medicinal uses; or where they can be procured fresh in most cases that would be prefered.

The herbs to be employed for impregnating the vapour about to be administered for the cure of any disease, are to be put into a vessel with many holes in its cover, like a colander. A tube opening into the side of this herb vessel, is to conduct steam to the herbs, by means of a pipe from a boiler at any convenient distance, and the herbs thus suffering a partial decoction, their virtues are taken up by the steam, and carried off through the perforations in the top of the vessel.

The bath in which this medicinal vapour is to be administered, may be constructed as a tent, with curtains to enclose the patient, the floor of which tent is to be perforated or grated to and from the lid of a box, in the interior of which box the herb vessel must be placed ; and the steam being thrown upon the herbs in the manner described, the impregnated vapour will rise from the vessel, and passing through the grating, fill the interior of the tent in which the patient is proposed to be seated, in a caned bottomed chair, or upon a slight stool.

In this way the virtues of any vegetable substances which are antidotes to the malady are proposed to be extracted, and communicated to a diseased person in the form of vapour, which being absorbed by the skin of the patient, enters the body, and effects the desired

cure.

The boiler proposed to be employed for generating the steam, is recommended to be of an elliptical form with the furnace in the interior, and the water surrounding it on all

sides. Such a boiler may be made portable, as one of small dimensions will be sufficient for the purposes of the above operation, and may be placed near the chimney in the room of the sick person.

Novel Enventions.

Steam Coach.

THE observations which we felt called upon to make in our last number, respecting the practicability of driving a stage-coach by the power of steam, have, as might be expected, brought upon us considerable animadversion; (indeed, we may say abuse,) but which has not in the slightest degree, shook the confidence which we felt, and still feel, that our view of the subject, as then expressed, is perfectly correct.

"Let him take a walk

"Sagacious writer!" says one. to the Regent's Park," says another. And what then? Why, "shew his eyes, and grieve his heart," there IS a steam coach in existence.

With great submission to our sagacious critics, and other sapient journalists, we dispute upon terms; what they call a steam coach, we do not call a steam coach; but merely an experimental loco-motive engine, with the body of a coach certainly now attached to it, but, in our cpinion, with scarcely any of the requisites which a steam

coach must have before it can possibly perform a jour

ney.

That this, said to be, steam coach frequently takes an excursion in the neighbourhood of the Regent's Park, we are perfectly aware of, but a few minutes observation of its performance will convince any one, however little acquainted with steam engines, that there are some things wanting before this machine can be called a steam coach.

Without entering into any investigation of its defects, or at present pointing out certain essentials which it does not possess, we have no hesitation in again declaring it not to be a steam coach in our sense of the word, and we shall persist in that opinion, until it can be made to run one stage of five miles in the course of an hour without stopping; then we will acknowledge it to be a steam coach; but at present, there does not appear to be any probability of this, or any other of the projected loco-motive vehicles performing even so very moderate a feat. Therefore, we again assure our readers, that there is not at present in existence, nor do we believe there is in any tolerable state of progress, a steam coach likely to be applied to public sur vice.

Among our numerous correspondents upon this subject, one gentleman, well known in the inventive world, tells us that he perfectly agrees with us in opinion, that steam coaches are impracticable, but that he has a something coming forward which will supersede their necessity -he is about to complete a STEAM HORSE.

Face Guard for Smelters.

THE sum of five Guineas has been presented by the Society of Arts, to Mr. J. CALLAGHAN, Carlisle-lane,

Lambeth, for his Face-guard for Smeliers; one of which. has been placed in the Society's Repository.

Mr. Callaghan's guard is intended to preserve the face, and particularly the eyes, of smiths, founders, stokers, and others, from being injured either by the heat of the furnace, or of red-hot or melted metal, or by fragments of metal dispersed on all sides, in the action of hammering.

The guard is of two forms, either a veil, as it were, of iron wire gauze of a curved form, and fastened by a hinge to the front part of the hat, or a mask, more or less complete, with the eye-holes covered with wire gauze.

There is not much novelty in the invention; spectacles of wire gauze are already in use, and eye-guards, fastened by a band round the head, have been employed by persons engaged in breaking stones for the roads.

It does not, however, appear that founders, stokers, and others, whose eyes are much exposed to radiant heat from burning fuel or melted metal, are in the habit of using any precaution to protect ther eyes. It appears from the concurring testimony of engine-makers, master-founders, and others, members of the Society, that the eyes of persons in their employ are often seriously injured from the above-mentioned causes. J. Callaghan is himself a workmen, and the Society have rewarded him in hopes that his fellow-labourers may be induced to avail themselves of the invention of one of their comrades, though they would probably neglect the very same contrivance, if offered to them from any other quarter.

CERTIFICATE.

This is to certify that I have bad Joseph Callaghan's face-guard tried at the forge, and at the air furnace in my father's manufactory, in one instance in forging a spindle of eleven hundred weight, and in the other, in dipping

metal from the air furnace; and on both occasions the men expressed their surprise at the trifling heat which they felt upon their faces; and I do not hesitate to assert, if the description of men above-mentioned would use these guards at an early stage of their profession, they would have their eye-sight wholly unimpaired for many

years,

Bridge-road, Lambeth.

CHARLES COLLINGE,

St. Helena Silk.

A specimen of the raw silk produced at the island to St. Helena, has arrived in England. It is the first perfect one, and is considered to be of a very fine quality. It is entirely free from any disagreeable odour, which speaks much in its favour. In last August the number of worms in progress was 218,000, which were in a very healthy condition, and expected to spin in the course of a few days. The mulberry trees thrive remarkably well, and have a very luxuriant appearance.
