The publication 1 of the fragment at first missing from the upper left-hand corner of the tabula Hebana (AE 1949, 215) so far confirms some conjectures which I made in a talk at Cambridge in 1951 that I am moved to print the briefest note about a point which does not seem so far to have been mentioned elsewhere.

Two experiments tested the hypothesis that children at the left of the distribution of right minus left (R-L) hand skill are at risk for poor phonological processing. In the first experiment, individual assessments of spoken rhyme awareness were made in 5- to 8-year-olds. In the second experiment, a group test of word order memory for spoken confusable and nonconfusable items was given to 9- to 11-year-olds. Evidence of poorer phonological processing in those at the left of the R-L distribution was found in both experiments. Rhyme judgements and word order memory were both associated with reading ability, but reading did not interact with effects for hand skill. A group test of homophone comprehension was given to the same children tested for word order memory. Homophone errors did not differ between hand skill groups, showing a dissociation between the two tasks for R-L hand difference. The findings suggest that some risks for phonological processing could be due to normal genetic variation associated with the hypothesized rs + gene (Annett, 1972, 1978).

The grant of arms here reproduced was made in November 1510, by Thomas Wriothesley, Garter King of Arms, to John Mundy, described as gentleman, of Chakenden (Checkendon) in the county of Oxford. It is written on a sheet of parchment 17¾ in. by 9½ in., which has suffered somewhat from damp ; the margins are decorated, as will be seen in the illustration (pl. xliii), with a rather coarse but effective design of flowers, while the arms and crest occupy the customary position on the left hand. There are two seals, both now detached from the document, enclosed in the usual wooden cases, which are a good deal worm-eaten ; the larger seal 2½ in. diameter, is that of the Garter Office : a cross between four doves with wings expanded; on a chief a crown within a garter between a leopard and a fleur-de-lys, with the legend: . The smaller (left-hand) seal 2 in. diameter is that of Wriothesleys' own arms, quarterly I and IV, a cross and four falcons for Wriothesley, II, Fretty and a quarter with a lion passant in the quarter, for Dunstaville, III, a pale lozengy and a border bezanty, for Lushill, but the legend is indecipherable, both seals having suffered greatly from abrasion.

Three hypotheses for the right-hand advantage in aiming movements were examined in these experiments: (1) the right-hand system is more efficient at processing visual information during the movement; (2) subjects make more use of visual information prior to movement initiation when using the right hand; (3) the right hand is less variable in generating force in initiating the pointing response as force demands increase. In the first experiment subjects pointed at a target located directly in front of them from two starting positions which defined short (25-cm) and long (35-cm) movements. The movements were made in three movement times, fast (150 to 249 msec), medium (250 to 349 msec) and slow (350 to 449 msec), under three vision conditions—full vision, and no vision (lights out) with immediate or delayed movement initiation. Performance was measured in movement time and accuracy in amplitude of movement. The results did not completely support any of the hypotheses regarding the right-hand advantage, although the left hand was generally more variable than the right. Also, variability increased with increases in movement length and decreases in movement time. The second experiment was designed to examine further the hypotheses regarding the right-hand advantage. In this experiment the same three visual conditions were used; however, subjects made only fast (<250-msec) movements. Also six rather than two starting positions were used. The increased variability of the left hand was observed again here. Further pointing accuracy with the left hand was more adversely affected in the no-vision delay condition. The implications of these results were discussed as they pertain to understanding the processes involved in visual aiming and the observed manual asymmetries.


The fundamental law of photo-electric activity states that ½ mv 2 = hv - w , (1) where the left-hand side represents the maximum kinetic energy of the liberated electrons, h is Planck’s constant, v is the frequency of the exciting light, and w is a constant which measures the work necessary for an electron to escape from the substance, and whose value is characteristic of the material under consideration. The equation (1) was first given by Einstein as a deduction from the view that the energy of radiation was distributed in discrete quanta. However, I succeeded in showing that it followed from Planck’s radiation formula; so that it evidently has a wider basis than the restricted and doubtful hypothesis used by Einstein. On the experimental side the evidence for several years was somewhat conflicting, but in 1912 I showed, as a result of experiments made in collaboration with Dr. K. T. Compton, that the equation represented the photo-electric behaviour in the visible and in the ultra-violet as far as λ= 2 x 10 -5 cm., for the metals sodium, aluminium, magnesium, zinc, tin, and platinum as accurately as it could be determined. The experiments also showed that the differences in the values of the constants w for different metals were connected with the corresponding contact potentials V by the relation w n - w m = e (V n -V m ).

In the course of examining Roman imperial medallions and coins in connexion with a study of Roman cult images, representations of Herakles Crowning Himself, a figure which appears on the reverses of medallions of Marcus Aurelius, Lucius Verus (Plate I, 2), and Commodus (Plate I, 3), merit further comment. These reverses, whether with or without legend, exhibit identical compositions. In the centre a young, beardless Herakles stands facing, his right hand raised in the act of placing a crown on his head; his left hand, close to his left hip, holds the club upwards in the crook of the elbow. Between club and elbow, the lion's skin hangs down over the forearm to a point midway along the left leg. The head, both forepaws, and tail are clearly visible dangling below. On all the medallions the die designer has made very clear the, important point that Herakles rests his weight on the left foot, with left hip thrown out and the right foot slightly back and out, giving a pronounced bow curve to the right side of the body from foot to shoulder. To Herakles' right and slightly behind him appears an apple tree on one branch of which hang the hero's quiver and bow; to his left rear is seen a square altar, festooned with garlands and with an offering burning on the top, and in her comprehensive monograph on Roman medallions J. M. C. Toynbee suggests that ‘the picture as a whole had been inspired by some bas-relief or painting now lost to us’. The question of relating the central figure to the whole composition will be taken up in Part II, in reappraising the general problem of famous statue types in medallion compositions. For the moment we may see what further progress may be made in identifying the statue type of the young Herakles Crowning Himself.

This paper presents a simple and compact coplanar waveguide (CPW)-fed circular-shaped reconfigurable patch antenna with a switchable circular polarization (CP) sense. The circular patch is cut at the ends vertically and switches are introduced to connect the patch ends. By controlling the ON/OFF status of the two switches, the polarization of the antenna can be switched between two states: left-hand circular polarization and right-hand circular polarization. The patch is designed on a very thin RT Duroid substrate of dielectric constant (εr) of 2.2 and thickness of 0.254 mm. The overall antenna dimensions are 35 × 30 mm. The antenna is designed and simulated using finite-element method -based EM simulator, HFSS. For each switching condition the return loss curve, radiation pattern are obtained. Axial ratio curves for polarization diversity cases are also plotted. Parametric studies have been made in order to get optimized values for certain antenna dimensions such as thickness, CPW ground to feed gap, etc.

From an old Italian collection there has come to Holland the bronze statuette here published, representing Poseidon as he is known to us from several marbles and bronzes and numerous Hellenistic and Roman coins. The god is shown leaning forward on his raised and bent right leg, his right forearm resting on his thigh, his left hand raised high. The statuette, which measures 17½ cm. in height, is in an excellent state of preservation; only the tops of the thumb and of three fingers of the right hand are missing; too vigorous cleaning has removed much of the patina; on the right side of the neck is a hole, probably a vent. The statuette is of very fine quality and excellent workmanship. In spite of its small size it is impressive and monumental, and strongly recalls a life-sized original; evidently this was a modelled, not a sculptured one; we have to think of a bronze statue. Coins of Demetrios Poliorketes, the figure on which shows exactly the same posture as our bronze, tell us that the right leg rested on a rock and the left hand held a trident.The most famous of this well-known type is the Lateran statue, which has been much discussed as to the authorship of its original. Unfortunately this is rather a bad example of a Roman copy, made in a very classicist taste, probably in the first half of the second century A.D.; moreover, it has been much restored. Helbig tells us that nose, left arm, both legs up to the knee, ship, dolphin and plinth are restored, while parts of the hair and beard are new.

The Woman—Dressed in the common mode of the fifteenth and sixteenth centuries — stands with her right, or sometimes left, hand extended forward, the second finger raised and stretched forth. The man, dressed similarly, confronts her, ring in hand, to place on her outstretched finger. There are others in attendance, principally a figure of dignity close to the pair and perhaps as many as ten or more spectators. The description is that of a wedding, in fact, a Jewish one. The action takes place exclusively between the bride and the groom, although in one version of this picture (there are many), the dignified third figure raises a cup in hand; in others, he is reciting words of blessing.

The energy profile for the transformation of the endo-tetrahydrodicyclopentadienyl cation A into the 1-adamantyl cation R has been probed by means of six separate experiments employing superacid techniques. Of the approximately 14 cations between A and R, required as intermediates for the above transformation, it can be shown that only one of these is capable of direct observation. This cation, the tricyclo[5.2.1.03.8]dec-3-yl (homobrendyl) cation J, is characterized in detail in one of the six experiments. The rate of the rearrangement of J into the 1-adamantyl cation has been measured. Cation J also undergoes a degenerate rearrangement, the dynamics of which can be probed using NMR line-broadening and selective inversion–recovery experiments. The relationship between the exo and endo tetrahydrodicyclopentadienyl cations D and A has been studied. Only A is directly observable, even though in some experiments direct precursors of D were used as cation sources. Several experimental probes were made in an attempt to detect the presence of a small equilibrium concentration of D, without success, and a rationale is provided for the much greater stability of A vs. D. The remaining four experiments involved the addition of neutral precursors to superacid solutions, but the initially formed (expected) cations could not be observed, only cations A, J, or R being observed instead. These "partitioning"-type experiments prove whether the corresponding left-hand or right-hand transition-state barriers are the lower in energy. In the case of starting with transient cation intermediate E, only observable cation J is obtained, showing that the barrier between B and E is the high point on the overall carbocation reaction profile.
