"SIR DAVID GILL (1843-1914), British astronomer, was born in Aberdeenshire June 12 18 4 3 and educated at the university of Aberdeen.
The most noteworthy waterfalls are - Scale Force (Dano-Norwegian fors, foss), besidesCrummock, Lodore near Derwentwater, Dungeon Gill Force, beside Langdale, Dalegarth Force in Eskdale, Aira near Ullswater, sung by Wordsworth, Stock Gill Force and Rydal Falls near Ambleside.
a, mouth; b, cephalic tentacle; h, gill (ctenidium).
Thus the base of the gill passes in a slanting direction across the right-hand side of the kidney, the posterior end being dorsal to the apex of the gland, and the anterior end ventral to the right-hand corner.
See David Gill, Man and Astronomer, by George Forbes (1916).
Captain William Gill, of the Indian survey, first made his way across China to eastern Tibet and Burma, and subsequently delighted the world with his story of the River of Golden Sand.
Moreover, he wrote an article in the Edinburgh Review of July 1805 criticizing Sir William Gill's Topography of Troy, and these circumstances led Lord Byron to refer to him in English Bards and Scotch Reviewers as "the travell'd thane, Athenian Aberdeen."
d, Left (archaic right) gill e, Reflected mantle-flap. fi, The fissure or hole in the mantle-flap traversed by the longitudinal incision.
To complete the account of the relations of the organ: the right anterior corner can be seen superficially in the wall of the mantlechamber above the gill.
Valvata is common in fresh waters throughout Britain; the gill when the animal is expanded is protruded beyond the mantle-chamber.
the gill-slits may be stated briefly as follows: - (a) the presence of two kinds of branchial bars in all species and also of small cross bars (synapticula) in many species; (s) numerous gill slits, from forty to more 1 - _ than a hundred pairs; (y) the addition of new gill-slits by fresh perforation at the posterior end of the pharynx throughout life.
Had the internal contacts alone been used, which many astronomers would have considered the proper course, the result would have been 8.776" In 1877 Sir David Gill organized an expedition to the island of Ascension to observe the parallax of Mars with the heliometer.
The failure of the method based on transits of Venus led to an international effort carried out on the initiative of Sir David Gill to measure the parallax by observations on those minor planets which approach nearest the earth.
The drawback of greater distance was, however, in Gill's opinion, more than compensated by the accuracy with which the observations could be made.
The instruments used were heliometers, the construction and use of which had been greatly improved, largely through the efforts of Gill himself.
These observations.were worked up and discussed by Gill with great elaboration in the Annals of the Cape Observatory, vols.
This last value agrees very closely with a determination made by Gill at the Cape of Good Hope, and most other recent determinations give values exceeding 20.50".
Zoologists are familiar with many instances (fishes, crustaceans) in which the protective walls of a water-breathing organ or gill-apparatus become converted into an air-breathing organ or lung, but there is no other case known of the conversion of gill processes themselves into air-breathing plates.
14.1130 indicates that there are 130 lamellae in the scorpion's lung-book, whilst 1150 indicates that 150 similar lamellae are counted in the gill of Limulus.

io) we have an example of a Lamellibranch retaining this plume-like form of gill.
The filaments of the gill (ctenidium) of Mytilus and Arca thus form two closely set rows which depend from the axis of the gill like two parallel plates.
As the axis of the ctenidium lies by the side of the body, and is very frequently connate with the body, as so often happens in Gastropods also, we find it convenient to speak of the two plate-like structures formed on each ctenidial axis as the outer and the inner gill-plate; each of these is composed of two lamellae, an outer (the reflected) and an adaxial in the case of the outer gill plate, and an adaxial and an inner (the reflected) in the case of the inner gill-plate.

Therefore, when gill drawing machinery was invented, the cutting of silk into short fibres ceased, and long silks are now prepared for spinning on what is known as " long spinning process."

Both the openings are close together, the external opening being just in front of the principal gill near the posterior end of the body.
The venous blood is conducted from the tissues to a large sinus on either side above the pallial groove, and from this sinus passes to the gills by an afferent vessel in each gill on the internal or pedal margin of the axis.
The oxygenated blood is carried from each gill by an efferent vessel on the external or pallial side of the axis to another longitudinal vessel which leads to the auricle on each side.
In Lepidopleuridae an osphradium occurs at the base of each gill.

It was at Ascension that Mr, afterwards Sir, David Gill determined, in 1877, the solar parallax.
The first really adequate determinations of solar parallax were those of Sir David Gill, measured by inference from the apparent diurnal shift of Mars among the stars as the earth turned diurnally upon its axis; the observations were made at the island of Ascension in 1878.
The disk of Mars and his colour are certain disadvantages, and Gill.
The measures were made with the Cape heliometer and have never been superseded, for the latest results with the minor planet Eros exactly confirm Gill's result-8.80" - while they decidedly diminish the associated probable error.

Sir David Gill derived a highly satisfactory value of 8.78" for the long-sought constant from the opposition of Mars in 1877, and from combined heliometer observations at five observatories in 1888-1889 of the minor planets Iris, Victoria and Sappho, the apparently definitive value of 8.80" (equivalent distance, 92,874,000 m.).

The members of the order present the same wide range of superficial appearance as do the Pectinibranchiate Streptoneura, forms carrying well-developed spiral shells and large mantle-skirts being included in the group, together with flattened or cylindrical slug-like forms. But in respect of the substitution of other parts for the mantle-skirt and for the gill which the more degenerate Opisthobranchia exhibit, this order stands alone.
