John Henry Gaddum was born on 31 March 1900 in Hale, Cheshire, the eldest child of Henry Edwin Gaddum and Phyllis Mary née Barratt. He had three brothers and two sisters. His father was a silk importer whose main energies were devoted to charitable work in Manchester, where he was a Justice of the Peace, and Chairman of many of the leading charitable committees. He got them all together in a house which was later called Gaddum House. Manchester University honoured him by giving him an honorary M.A. About his father, Gaddum wrote: ‘As the eldest I got more help from him than did the rest of the family. He made me fond of riding and natural history, and taught me to use my hands. He constructed a large sundial which was also a summer house, and which told the correct time to within about a minute at all times of the year—making due allowance for the apparent irregularities of the sun at different times of the year. It also told the day of the year. He was fond of sketching and taught me to draw— but not very successfully. He made me fond of long walks in Wales and Switzerland, and of swimming and sailing.’ John Gaddum’s maternal grandfather, Alfred Barratt, was, as Gaddum wrote, a clever man. He went from Rugby to Balliol, Oxford, under Jowett, and there achieved what was then a record in examinations: a double first in Moderations followed by First Class in Classics, Mathematics and Modern History. He wrote two books on philosophy and died young (35). A first cousin of Gaddum’s mother was Sir Samuel Hoare, later Lord Templewood, at one time Foreign Secretary and Ambassador to Spain. Another first cousin of his mother was Dick Acland, who was Bishop of Bombay and by whom he was married. A first cousin of his father, Grace Joynson, married William Hicks, who became Lord Brentford and who was Home Secretary at the time of the General Strike in 1926.

In the early part of the nineteenth century the Dupont brothers ran separate natural history businesses in Paris. Relatively little is known about their early life but an investigation into the family history at Bayeux corrects Léonard Dupont's year of birth from 1795 to 1796. In 1818 Léonard joined Joseph Ritchie's expedition to North Africa to assist in collecting and preparing the discoveries but he did not get beyond Tripoli. After 15 months he came back to Paris with a small collection from Libya and Provence, and returned to Provence in 1821. While operating as a dealer-naturalist in Paris he published Traité de taxidermie (1823, 1827), developed a special interest in foreign birds and became well known for his anatomical models in coloured wax. Henry Dupont sold a range of natural history material and with his particular passion for beetles formed one of the finest collections in Europe; his best known publication is Monographie des Trachydérides (1836–1840). Because the brothers had overlapping interests and were rarely referred to by their forenames there has been confusion between them and the various eponyms that commemorate them. Although probably true, it would be an over-simplification to state that birds of this era named for Dupont refer to Léonard Dupont, insects to Henry Dupont, and molluscs to their mother.

We provide the first comprehensive data on the questionable distribution of the genus Pelophylax and the family Ranidae from Pakistan. Based on a literature review and two specimens of the genus from Tasp, Panjgur District in Pakistani Balochistan (USNM 26194–95), stored in the Smithsonian National Museum of Natural History, Washington, DC, USA, we discuss the possible occurrence and affiliation of these frogs in the context of Central Asia. Our comparison shows that the nearest records of Pelophylax in relation to the Tasp specimens are reported from more than 280 km (air-line) away in Iran and Afghanistan, which are currently separated by hot and mostly desert environments. We suggest that possible surviving populations of this genus may still be present in Balochistan (Rakhshan River) or Khyber Pakhtunkhwa (Kabul River) Provinces of Pakistan. This would, however, need further field investigations.

Rectal prolapse is an overall rare occurrence in children in the first 4 years of age. It typically tends to relapse. In the majority of cases it is not possible to highlight a single cause that determines prolapse, even if it is more frequent in children who suffer from constipation. In about 1 in 10 cases there is an underlying predisposing anatomical-neurological condition (in particular neurological: myelomenigocele, spina bifida occulta). A predisposing cause that must always be considered and excluded is cystic fibrosis, even in the age of newborn screening. Rectal prolapse management is conservative in most cases. Behavioural measures (correct toilet training, good hydration, diet rich in fibres) and the use of the macrogol laxative are fundamental. The prolapse that does not resolve spontaneously must be reduced manually by instructing the family on the technique to be used. In 90% of cases the natural history of rectal prolapse is favourable, with complete resolution within the first 4 years of age. After this age, it occurs more rarely. Surgery is rarely indicated. The current techniques that have a large consensus are sclerotherapy and laparoscopic rectopexy. The paper reports the management of recurrent rectal prolapse in a 3-year-old boy.

Though a frequent problem with a tremendous negative impact on the family as well as the child, fecal incontinence has received little attention in the pediatric literature. Levine's study of the natural history of children with encopresis in this issue of Pediatrics is, therefore, a welcome contribution. Encopresis is defined as incontinence of feces not due to organic defect or illness. Mercer preferred to define encopresis as the voluntary or involuntary passage of an ordinary bowel movement into the clothing, and soiling as the constant involuntary seepage of feces associated with impaction. He reported that the former was rare in his experience.

Created by pioneering mathematicians and engineers during times of political unrest and war, computers are more than electronic machines. Underneath the myriad complicated circuits and software glows a mathematical purity that is simplicity itself. The maths at the root of computers illuminates the nature of reality itself. Today explorers of the impossible still compete to find the limits in our universe. With a revolution in mathematics and technology and a million dollars at stake, who can blame them? . . . It was 1926 and the General Strike was taking place in England because of disputes over coal miners’ pay. There were no buses or trains running. Fourteen-year-old Alan Turing was supposed to be starting at a grand boarding school: Sherborne in Dorset. Yet he was living in Southampton, some sixty miles away. Many children would have simply waited for the ten-day strike to finish and have a longer holiday. Not Turing. He got on his bike and began cycling. It took him two days, with a stay in a little hotel halfway, but young Turing made it to his new school on time. Turing’s independence may have stemmed from the fact that he and his older brother John had seen little of their parents while growing up. Both parents were based in India, but decided their children should be educated in England. The boys were left with friends of the family in England until their father retired and returned in 1926—just as Turing made his way to the new school. It was an impressive start, but Alan Turing didn’t do very well at his new school—he never had in any previous school. His handwriting was terrible, his written English poor. His English teacher said, ‘I can forgive his writing, though it is the worst I have ever seen, and I try to view tolerantly his unswerving inexactitude and slipshod, dirty, work . . .’ The Latin teacher was not much more approving. ‘He is ludicrously behind.’ The problem was that Turing didn’t pay attention to the curriculum being taught. Instead he spent more time following his own interests.

Recently, we (Akkari & Enghoff 2011) described a new species of the genus Rharodesmus Schubart, 1960, discussing the taxonomic state of the family Pyrgodesmidae and providing notes on the four genera occurring in the west Palaearctic area. However, we failed to present details on the holotype of the new species, which we now provide in this note in order to make the species name available. Thus, we describe here the new species Rharodesmus tabarkensis Akkari & Enghoff by reference to the full description given in Akkari & Enghoff (2011) with the following information on the type material: Holotype ♂, TUNISIA, NW, Jendouba Governorate, Tabarka, N36°57.8, E8°44.6, alt. < 40 m, coastal slope below the Genoese fort, under stones, 9.iii.2009, N. Akkari & H. Enghoff leg. (Natural History Museum of Denmark, Zoological Museum, University of Copenhagen, ‒ ZMUC); Paratypes: 12 ♂♂, 8 ♀♀, 14 juveniles, same locality and date as holotype, N. Akkari & H. Enghoff leg. (ZMUC).

Francis William Rogers Brambell was born on 25 February 1901 at Combridge House, Sandycove, Co. Dublin. His family tree is best set out in diagram (see the table on the next page). As he said himself, he could not remember a time when natural history was not his chief interest, nor did he know who inspired this interest, unless it was his maternal grandfather, F. W. Rogers, who certainly encouraged it. Rock pools on the shore, the rubbish brought in by fishing boats, insects, birds and other animals absorbed much of his attention after he was five or six years old. When Brambell was eleven T. P. Le Fanu introduced him to R. M. Barrington of Fassaroe, whose influence was probably decisive in developing his bent for natural history. Brambell went with Barrington and his children on ornithological expeditions, had the free run of Barrington’s collection of bird skins, and through him got to know most of the Irish naturalists of the time. He was, Brambell says, a grand field naturalist with an extraordinary gift for inspiring young people. At thirteen Brambell started seriously collecting bird skins. He never, he says, ever had any encouragement in biology or any other branch of science from his school.

Sheina Macalister Marshall, who was born on 20 April 1896, was the second of the three daughters of John Nairn Marshall, M.D., of Stewart Hall, Rothesay. Their grandfathers on both sides of the family came of farming stock. Her mother, Jean Colville Binnie, had a great grandfather who took Linlithgow Castle from the English for Robert the Bruce, and there were Covenanters on both sides of the family, one of whom fought at the Battle of Drumclog. Both sides were strong members of the Scottish Church and the Calvinistic characteristics of probity and hardiness were carried down to the daughters. Sheina was educated first by a governess at home and then at Rothesay Academy and at St Margaret’s School, Polmont. She evidently acquired an early interest in science for during her schooldays, when she was ill for two separate years with rheumatic fever, she read many of Charles Darwin’s books. The sisters received much encouragement in the study of natural history from their father who was a much loved G.P. and surgeon of the old school. He was an Honorary Member of the Glasgow Faculty of Physicians and Surgeons. He founded the Buteshire Natural History Society, which 50 years ago became responsible for the Rothesay Museum. The children kept a freshwater aquarium and made a dried flower collection for the Rothesay Museum. Their mother was also gifted, being musical, a great reader, and a good needlewoman who passed on this gift to Sheina. She took an active part in setting up the District Nursing Association in Rothesay.
