Vierordt's (1868) law states that when estimating the duration of a previous task, people overestimate short durations and underestimate long ones. We examine whether this same pattern holds for remembered and predicted duration for tasks lasting between 1 and 15 min. In support of Vierordt's law and its extension to future duration estimates, task duration tended to be overestimated for short ...
Although body temperature had been measured sporadically as a sort of novelty for a number of years, it was not until 1868 when the German physician, Wunderlich, published the results of his monumental researches on clinical thermometry that the tremendous usefulness of the thermometer as an instrument of physical diagnosis was widely recognized. Wunderlich's book, the compilation of sixteen ye...
In order to study large variations or fluctuations of finite or infinite sequences (time series), we bring to light a 1868 paper of Crofton and the (Cauchy-)Crofton theorem. After surveying occurrences of this result in the literature, we introduce the inconstancy of a sequence and we show why it seems more pertinent than other criteria for measuring its variational complexity. We also compute ...
Karyotypes of two species of the African annual killifish genus Nothobranchius Peters, 1868, Nothobranchius brieni Poll, 1938 and Nothobranchius sp. from Kasenga (D.R. Congo) are described. Both species displayed diploid chromosome number 2n = 49/50 for males and females respectively with multiple-sex chromosome system type X1X2Y/X1X1X2X2. The karyotypes of studied species are considerably diff...
The present paper treats 27 species and one species complex of the leafhopper genus Balclutha Kirkaldy from China, including descriptions of four new species, Balclutha bidentifurcata, B. parapunctata, B. paralucida and B. tricornis spp. nov., and gives six new records for China. One new synonymy, B. fuscoinaculatus Dai, Li & Chen, 2004, as a junior synonym of B. saltuella (Kirschbaum, 1868), i...

An identity by Chaundy and Bullard writes 1/(1− x)n (n = 1,2, . . .) as a sum of two truncated binomial series. In a paper which appeared in 2008 in Indag. Math. the authors surveyed many aspects of this identity. In the present paper we discuss much earlier occurrences of this identity in works by Hering (1868), de Moivre (1738) and de Montmort (1713). A relationship with Krawtchouk polynomial...
