from the bottom of the boat belonging to the Hercules, taken after the boat had been only twenty-one days afloat on the Gambia. One specimen, Balanus radiatus, Sowerby, measures five-eighths of an inch in longest diameter of base; and the other three, Chelonobia testudinaria, Linnæus, variety, vary from three-quarters to one inch in longest diameter of base. The names above given have been kindly supplied by Mr. F. P. Marrat.

The Rev. H. H. HIGGINS then read the following Paper on "Our Social Wasps," with a note on a specimen of Polistes, taken at Ince Blundell :

The true social wasps in this country are not of many kinds. In the south of Europe the species are more numerous, and in Brazil they are abundant. During an excursion of the Liverpool Naturalists' Field Club, in August last, to Ince Blundell, a member of the club, Mr. W. H. Mountfield, of the Liverpool, London and Globe Insurance Office, brought me a hymenopterous insect which he had just taken. It was, I felt sure, of a kind not known as a British species. Subsequently, on comparing the insect with "Monographie des Guêpes Sociales," by M. de Saussure, at the Liverpool Museum, I felt no doubt that the insect belonged to the genus Polistes, of which we have no native examples, and, with Mr. Mountfield's kind permission, the insect was sent to Mr. Frederick Smith, of the British Museum, who wrote as follows. "A few years ago specimens of a South American species of Polistes were taken at Penzance, in Liverpool, and in the London Docks. Those found at Penzance were fully accounted for. A vessel laden

with raw hides entered the harbour, and numbers of the Polistes were imported. A lady, whose house had windows at the back facing the harbour, took several in her bedroom and sent them to me. The captain of the vessel said that when they left Rio the flies swarmed on deck, and many accompanied the vessel throughout the voyage." Mr. Smith considers the Ince Blundell specimen to be Polistes binotatus of De Saussure, a native of Brazil, which does not appear to have previously been taken in England.

The social wasps of Britain have been figured and described in a work, not half so well known as it deserves. to be, by Dr. Ormerod, published in 1868 by Longmans & Co. There are only seven species, of which the largest is the hornet, an insect generally regarded with fear and aversion, but capable of being domesticated and utilised as a household pet see a paper in the German Entomological Magazine, by Pastor Muller, 1817. The following brief account, mainly from Dr. Ormerod's book, refers to the common wasp, Vespa vulgaris. The large wasps we see during the first warm days in spring are females, or mother wasps, which have passed the winter in concealment. What with late frosts, rains, birds, and little boys, comparatively few of the wasps which have lived through the winter survive to become the founders of colonies. When at last the wanderings of the future queen have come to an end, and she has discovered a hole or a branch to suit her taste, she enters on the work of her life. The first rudiments of the nest that is to be appear in the form of a little grey cap, suspended by the button at the top from a root or branch. Within the cap, with their openings downwards, are constructed four shallow cells, in each of which an egg is firmly glued. These cells are deepened as the enclosed eggs are hatched, an event attended with the earliest perils of wasp-life, the peril of dropping out of their cradles. Some perish in this way,

notwithstanding the admirable prehensile appliances with which the larva is furnished, consisting of the future mandibles at one end and a kind of disc at the other. The first perfect insects that appear are workers, which, as in the bees, are females not fully developed. By this time the queen has lost her power of making building-paper, her supply of saliva being exhausted, or rather diverted, and henceforth her duties are maternal, whilst the workers extend the nest from a little fairy ball, which might be hid in an egg-cup, to a great paper city. The loss of a queen amongst the wasps is not attended by the confusion which prevails when a similar calamity befals a community of bees. The workers continue to build; they even lay eggs, but the eggs laid by workers produce only male wasps or drones, and the swarm gradually dies away. Towards the close of summer the eggs laid by the queen produce drones and females; the latter do no work in constructing the nest, which they seldom leave except for short distances to bask in the sunshine. They are carefully fed by the workers with the best of the food brought home, and by the time that the wasp community finally breaks up they are in a condition resembling that of the bears before they take up winter quarters. Every available space within the bodies of these future mother wasps is stored with masses of fat for consumption during the long winter retreat. Whilst I read these notes they are quietly sleeping, tens of thousands of them, it is hard to say where; but in March or April next they will make their appearance and enter upon the duties of providing for a succeeding generation.

The drones may be known by their much larger antennæ. No male insect has a sting. Wasp paper is made of vegetable fibres, masticated by the powerful jaws or mandibles of the insect. These jaws open transversely, not longitudinally, as ours do. The researches of Dr. Landois have established the fact that the hum of insects is not produced by the

organs of flight. On the abdomen and on the thorax may be observed little apertures called spiracles; these are respiratory openings, and with them are connected the trachem, or air tubes. The proper instrument of voice answering to our vocal chords, or nearly so, is a little horny comb, which is placed across the spiracle, and vibrates like the tongue of a Jew's harp or accordion with the passing current of air. This explains what I have often heard from a bee, a shrill hum when the wings have been confined. The wings modify, but do not produce the hum.

For further information on the life history of the social wasps, I may refer to a beautiful work by the Rev. J. G. Wood, Homes without Hands, the best of all his numerous works; and to the still more recent, and, as indicating a patient, loving search after truth, more wondrous investigations accomplished by Sir John Lubbock, which appeared first in Nature, and afterwards in his work on "Insect Life."

SECOND ORDINARY MEETING.

ROYAL INSTITUTION, November 1st, 1875.

J. A. PICTON, F.S.A., PRESIDENT, in the Chair.

Ladies were present at this Meeting.

Messrs. W. H. Picton, Stevenson, Edmunds, Wilson, Prytherch, M.D., Doyle, and Lutschaunig were elected ordinary members.

Dr. CAMPBELL BROWN exhibited the magneto-electric machine, constructed on M. Gramme's principle, and illustrated its powers by several experiments.

Dr. CARTER exhibited a growing specimen of the Eucalyptus, and also a jalap plant, brought from the Botanic Gardens.

Dr. NEVINS exhibited a living specimen, recently born, of the snapping turtle.

The PRESIDENT read the following communication:

I wish to communicate to the Society an episode, in the literary history of Liverpool, which may not be without its interest.

The publication of Mr. Curtis's mock heroic Latin poem of "Via Audax," giving a description of Bold Street, brought to my memory a jeu d'esprit of a similar character, published in 1820, in the Kaleidoscope, a local weekly literary journal, edited by Mr. Egerton Smith, of the Liverpool Mercury. It was entitled "Liverpool, an Heroic Poem, in Six Cantos," only four of which, however, saw the light.

The style and metre were those of Lord Byron's Beppo and Don Juan, mingling

"The grave and gay, the lively and severe."

The poem exhibited decided talent, and attracted much attention, which was increased by the mystery and oddity by which its issue was surrounded. I will quote a verse style, which will also

or two at random, to illustrate the show the enormous changes in the aspect and customs of the town which fifty-five years have brought about. He is describing Lord Street, which was then exceedingly narrow.

[ocr errors]

Thy beauties, Lord Street, next attract the eye

(The Corporation should have made thee wider);
Along its well-trod pavement you may spy
Cart, carriage, gig, pedestrian and rider;
Here slumbering mud-beds ' lend their sullen dye,'
So if you wish to cross, take a good stride, or
Perhaps your foot by some curst chance may dart in,
And soil th' unrivalled jet' of Day and Martin.
