XV.—The Correlation between Relatives on the Supposition of Mendelian Inheritance.
Tập 52 Số 2 - Trang 399-433 - 1919
Several attempts have already been made to interpret the well-established
results of biometry in accordance with the Mendelian scheme of inheritance. It
is here attempted to ascertain the biometrical properties of a population of a
more general type than has hitherto been examined, inheritance in which follows
this scheme. It is hoped that in this way it will be possible to make a more
exact analy...
XVIII.–The Histology of Disseminated Sclerosis
Tập 50 Số 3 - Trang 517-740 - 1916
The research of which this paper gives an account was originated by the late Dr
Alexander Bruce and undertaken in conjunction with him; most of the material
used had been accumulated by him during the later years of his life. The
following preliminary communication made to the Pathological Society of Great
Britain and Ireland in July 1910 represents in brief outline the position which
had been rea...
XVIII.—Experiments on Colour, as perceived by the Eye, with Remarks on Colour-Blindness
Tập 21 Số 2 - Trang 275-298 - 1857
The object of the following communication is to describe a method by which every
variety of visible colour may be exhibited to the eye in such a form as to admit
of accurate comparison; to show how experiments so made may be registered
numerically; and to deduce from these numerical results certain laws of
vision.The different tints are produced by means of a combination of discs of
paper, painted...
XXIV.—On Old Red Sandstone Plants showing Structure, from the Rhynie Chert Bed, Aberdeenshire Part I. Rhynia Gwynne-Vaughani, Kidston and Lang
Tập 51 Số 3 - Trang 761-784 - 1917
The chert of the Muir of Rhynie, containing plant-remains, was discovered by Dr
W. Mackie of Elgin while investigating the sedimentary and volcanic rocks of
Craigbeg and Ord Hill which occur in that area. The original discovery was made
on loose specimens, built into the dykes or scattered over the fields,
especially those lying to the north of the road which runs from Rhynie to
Cabrach, and east ...
XXXII.—On Old Red Sandstone Plants showing Structure, from the Rhynie Chert Bed, Aberdeenshire. Part IV. Restorations of the Vascular Cryptogams, and Discussion of their bearing on the General Morphology of the Pteridophyta and the Origin of the Organisation of Land-Plants
Tập 52 Số 4 - Trang 831-854 - 1921
This part of the account of our examination of the plants preserved in the
silicified peat-bed of early Old Red Sandstone age found at Rhynie will be
devoted to the consideration of a number of general questions concerning the
four Vascular Cryptogams which it has yielded.1. In the first place the
morphological characters of Rhynia Gwynne-Vaughani, R. major, Hornea, and
Asteroxylon will be reviewe...
II.—On the Structure of Calymmatotheca kidstoni Calder (emended) and Genomosperma latens gen. et sp. nov. from the Calciferous Sandstone Series of Berwickshire
Tập 64 Số 2 - Trang 29-44 - 1960
SynopsisThe Lower Carboniferous fossil Calymmatotheca kidstoni Calder is shown
to be a simple seed and is redescribed under the new name Genomosperma kidstoni.
A second species G. latens is also described. Genomosperma gen. nov. is of
interest in possessing a free nucellus with a lagenostome and short salpinx. The
nucellus is surrounded by an integument of about eight lobes which are free from
one...
XII.—On the Structure of Samaropsis scotica Calder (emended) and Eurystoma angulare gen. et sp. nov., Petrified Seeds from the Calciferous Sandstone Series of Berwickshire
Tập 64 Số 12 - Trang 261-280 - 1960
SynopsisThe Lower Carboniferous seed Samaropsis scotica Calder has been
re-investigated from new material and assigned to a new genus Lyrasperma. It is
shown to have a nucellar apex with a pollen chamber and a funnel-like structure
interpreted as an expanded salpinx. The free parts of the two integumental lobes
diverge as apical horns; there is therefore no micropyle. Eurystoma angulare
gen. et sp...
IX.—Stamnostoma huttonense gen. et sp. nov.—a Pteridosperm seed and cupule from the Calciferous Sandstone Series of Berwickshire
Tập 64 Số 9 - Trang 201-215 - 1960
SynopsisStamnostoma huttonense is a petrified seed assigned to the
Lagenostomales. The open upper part of its integument shows no lobes or
chambers. The short wide salpinx is inserted within a relatively wide
“micropyle” and is partly invaginated into the top of the lagenostome which
usually contains pollen. The female gametophyte is known, it has a domed
“tent-pole” and three archegonia.The paire...
II.—The Varying Form of the Stomach in Man and the Anthropoid Ape
Tập 45 Số 1 - Trang 9-47 - 1906
There are few organs which have engaged the attention of the topographical
anatomist more than the stomach, and few which have yielded him so small a
reward as the result of his labours. The changes which so rapidly set in after
death through relaxation of its muscular wall, combined with the many different
forms which the organ may assume during life, make the investigation one of
great difficult...
XII.—On Salpingostoma dasu: A New Carboniferous Seed from East Lothian
Tập 60 Số 2 - Trang 427-464 - 1942
In a recent paper (Gordon, 1938) reasons were given for the belief that
semi-arid conditions prevailed during Lower Carboniferous times in the
neighbourhood of North Berwick, East Lothian. The evidence was opposed, in a
measure, to that advanced by Mr George Barrow in the East Lothian Memoir (1910)
to substantiate the same position. He had relied on the absence of fossils as
part proof; but, in po...
