fifteenth century, on the site of a more ancient siastical settlements; also a cave, said to have been church. In its vicinity are the ruins of various inhabited till recently, the last occupants being some of the Patriots, who, after their defeat, fled to Aran to escape the butchery that was going on in Ireland, at the dawn of the present century.

On Aranmore, the village now called Killeany, was the first Christian settlement, St. Eude, the apostle of the island, having resided here

and founded Teampullmore and a monastery. These are now gone, having been carried away by the Cromwellians to build the fortress of Arkin. Here it may be mentioned, that St. Eude is supposed to have come across from the opposite coast of Connemara on a large flat granite block. This stone is shown at a small bay on the south-east coast, and called Cloghnacurrach, or the stone boat. At Killeany there is the

butt of a round tower; fifty Fig. 171. Terminal Cross or Tearmon. years ago this is said to have

been 40 ft. high. From the style of the building, the tower would appear to have been much more modern than many of the churches on the islands, which is very probable, as Fig. 172. Typical Irish Cross at Clommacnoise. many, if not all, the round towers in Mayo and Galway were built about the tenth or eleventh buildings, while its tearmons, with the terminal century, that of Annaghdown, on Lough Corrib— crosses, have been previously described.

in Colgan's list Kilnamanach, or the Church of the Monks, dedicated to St. Caradoc Garbh (the rough). Farther westward, in the neighbourhood of the village called Cowrugh, are various ruins, about which very little is known. One church has the remarkable and poetical name of Teampull nag ceatharaluinn, or the "Church of the Four Beautiful Ones ”; near it is their grave, and a well dedicated to them. We may also call attention to two bullāns, two liagān, several cloghāns, a cashel, a laura ; also the village of Ballynasean, previously described, as it is supposed to be in part preChristian.

Kilmurvy, farther west, signifies “ the church on the sand.” Such a church does not now exist, if it is not buried. At or near the village are Teampullmacduagh; Teampullnaneeve or Teampullbeag, as it is known by both names; and a third, the name of which is forgotten; a holy well, a tall stone cross, and the site of a fifteenth-century monastery, once famous as a seat of learning. The first of these churches lies inside a cyclopean fort or cashel.

Farther north-west, near the north shore of the island, is the village of Onaght, but known to and called by the Aranites, as Bally-na-seacht-teampull, or the village of the seven churches. Here there are now only two churches, Teampullanphoill, or the church of the liole, and Teampullbrecan; but there are the sites of numerous buildings, some of which may be the remains of the churches after which the place is called. Teampullbrecan was called after the founder of the settlement, and his grove is shown, marked by a cross cut in a flag. There are also two elaborately carved stone crosses that have been broken up; the pieces, however, some years ago were collected by Sir W. Wilde and S. Ferguson, M.R.I.A., and it is to be hoped by this time they are restored as far as practicable. Near the church is a holy well; also a labba, the latter said to cure sterility in the human race.

As a conclusion to this brief sketch of the antiquities of Aran, attention may be drawn to the rich field of ancient lore which lies here unworked. There is the limestone cave on the middle island, which probably contains relics of the pre-historic man; the buried habitations and other structures; the dirt-heaps or kitchen middens at the Pagan and ancient Christian babitations; also the artificial mounds, about which nothing is known, wbich may be either cnocāns or tuiams.

USEFUL SLIDES.-Like, I dare say, many of the younger readers of SCIENCE-GOSSIP, and students of microscopy, I have to exercise considerable economy, and mount my own objects ; naturally I am desirous of stocking my cabinet with really useful and in. structive slides, and, as the winter season approaches, and students have more leisure at their disposal, I venture to take up a little of your room, and make an appeal to your readers for assistance, trusting that out of their experience they may be able to advise and instruct not only myself, but others who likewise are young students in this absorbing pursuit, My first difficulty is with whole insects, which are so necessary to study. With some specimens from the Coleoptera, the Diptera, and Hymenoptera, I think I may say I have been fairly successful; but with many specimens from the last-named two orders I have failed, the delicacy of the wings, and the extreme hardness of the chitine of the head and thorax, being the stumbling-blocks in my progress : thus, long before the thorax is sufficiently soft to admit of flattening out, the wings have been acted upon so strongly by the liquor potassæ, that the two membranes separate, and tear under the most delicate manipulation which I can bring to bear upon them. Doubtless many of your readers have encountered and triumphed over this difficulty; and I trust that they will favour me with full particulars of their method. Perhaps because I am a very young student I sympathize strongly with those microscopists who go in for pretty objects, even though, as in the case of many seeds and diatoms, no real knowledge can be obtained from such objects. We see so many things in the moral world made ugly and distorted by crime and folly; we see so much of misuse in the natural world, resulting in that which is offensive to the eye and painful to the mind, that we may surely be allowed the luxury of observing that which is pleasing in art and nature. Though we concede so much, it is undeniable that objects must be beautiful to the mind as well as to the eye, and to be this their structure and also their adaptability to the place in nature which they fill, must be clearly manifested, and therefore the cabinet of every microscopist should contain numerous slides of sections and delicate dissections of entomologicalobjects. I have long desired to possess slides of antenna which would clearly show the nerves, and have tried (once only) the bleaching preparation recommended by Dr. Hicks (see the article in the February number of SCIENCE-GOSSIP for 1874), but without the least result as regarded the manifestation of the nerves. Have any of the readers of SCIENCE-GOSSIP made the experiment, and with what result? Many learned writers have spoken of these nerves as objects easily observable in well prepared antennæ,
