Abstract
The Quarterly Journal of Microscopical Science for March 1887, vol. xxvii. Part4, contains:—On the termination of nerves in the liver, by A. B. Macallum (plate 36). These researches were made on the livers of man and Menobranchus (Necturus): the liver cells of the latter are from two to four times the diameter of those in man, and so were very favourable for these investigations; in man fibrils from the intercellular plexus of nerves give off excessively minute twigs, which terminate each in a delicate bead in the interior of the hepatic cells, near the nucleus; in Menobranchus the simple intracellular nerve-twigs always terminate in the neighbourhood of the nucleus, either singly or after branching, each terminal point being a delicate bead.—On the nuclei of the striated muscle-fibre in Necturus (Menobranchus) lateralis, by A. B. Macallum.—The development of the Cape species of Peripatus, Part 3: on the changes from Stage A to Stage F, by Adam Sedgwick, F.R.S. (plates 34–37). This elaborate memoir does not permit of being use fully summarised.—Morphological and biological observations on Criodrilus lacuum, by Dr. L. Örley.—Studies on earthworms, No. 3: Criodrilus lacuum, Hoffmeister, by W. B. Benham (plate 38). This little worm was first discovered by Fritz Müller in 1844, near Berlin, and was in the following year described by Hoffmeister; it was next found near Linz, and more recently in Italy and at Buda-Pesth by Dr. Örley, whose paper thereon has been translated from the manuscript by Mr. Benham. In the Danube this worm occurs, often in large numbers among the roots of Sium latifolium, the egg-cases looking like certain forms of Enteromorpha. The specimens dissected by Mr. Benham were sent to Prof. Lankester by Dr. Örley.—Notes on the chromatology of Anthea cereus, by Dr. C. A. MacMunn (plates 39 and 40). The pigments of Anthea are the pigments of certain marine Algæ, and are without doubt the pigments of the “yellow cells” which are now known to be unicellular Algæ.—On Ctenodrilus parvulus, nov. spec., by Dr. Robert Scharff (plate 41). This little Annelid was recently discovered by Mr. Bolton, of Birmingham, but its exact habitat is unknown. —On the relation of the Nemerteæ to the Vertebrata, by Prof. A. A. W. Hubrecht (plate 42); with permission from Prof. Hubrecht's Report on the Challenger Nemerteans.
