The late Mr H. T. M. Witham read in 1830 to this Society, and published three years afterwards in greater extension, an inquiry of much interest respecting two fossil trees found in Craigleith Quarry, a mile and a half from the north-west outskirts of Edinburgh. The general points of this inquiry are, that trees of very great size lie, completely fossilised, in the very compact sandstone of the quarry, at a great depth below the rock surface, slightly inclined to the-dip of the strata, with their structure so finely preserved in the fossilising material as to be beautifully shown before the microscope, and recognised as that of the Pinaceous Family, and of the section to which belongs the existing Araucaria. These trees have been generally known to fossile botanists by the name of Araucarioxylon Withami. An opportunity having occurred this year of confirming and extending the inquiries of Witham, it has been thought right to take advantage of it, again through the medium of the Royal Society.

The City

Traces of fortifications around the area apparently once occupied by the city of Old Smyrna were observed by Louis Fauvel, and our first detailed description of them is that of Prokesch von Osten, who accompanied him there on a second visit in 1825. As we shall see later, it seems likely, though proof is no longer possible, that most of the circuit wall around the tell, as well as that on the low spur to the west of it on which the modern village now stands, as described by Prokesch, may have belonged to the defences of the classical city. Nothing today survives of these above ground, owing to extensive stone-plundering in the interval; and it is to be feared that the fate of much of this rather exposed classical enceinte has been to provide masonry either for the houses of the modern village or for the terrace walls which today encircle the tell.The plundering of this outermost circuit probably left the earlier ones inside it rather more exposed to view. I have not been able to verify which of the city walls it was that was photographed by Keil in 1911, but when Franz and Helene Miltner excavated here in 1930 a part of the late-seventh-century B.C. circuit was visible on the east side of the city. Here they cleared about 80 metres of its face, for the most part to no great depth, then picked up its line again with a small probe some 20 metres farther north. Two further small trenches seem to have located more of this late-seventh-century wall-line south-south-west of their long cut, in addition to traces of yet other circuits. Besides this they report sinking two shafts into the mound dominating the north-west corner of the tell and making two small probes in occupation levels within the city itself.

Scottish Lochs

Our first investigation of Scottish plankton in 1901–2, although only tentative and somewhat meagre, was sufficient to show that, as regards the phytoplankton, the lochs of the west and north-west of Scotland were probably richer than any lakes previously examined. Owing to the extraordinary richness of the few collections then examined, it was considered eminently desirable that the investigation should be further extended. This we have been enabled to do by means of a third successive grant from the Royal Society, and the present paper is one of the results of a visit to the north-west of Scotland in July, August, and September, 1903.

Mem. The thermometer marked A was hung within the southern, or lower observatory; in such a part as we judged would be least affected by the fire; close to, and with its ball exactly of the same height with, the quicksilver in the bason of the barometer: that marked B was hung without doors, on the north side of the observatory. The floor of the observatory might be above 50 feet above the level of the sea at low-water mark.

In former papers I have described central Lancashire as capable of division into three plains of different elevations. The lowest being often beneath high-water mark, and always below the 25-foot Ordnance contour; the second ranging from 25 and 50 feet to 500 feet above the sea, terminating at the foot of the steep escarpment at the western edge of the Lancashire and Yorkshire moorlands forming the Pendle portion of the Pennine chain, with an average elevation of 1200 feet. Both the lower plains are much covered with drift, and the rock-surface at the sea-coast is often 50 feet below low-water mark, steadily rising in one gradual inclined plain, eastwards, or towards the Fells.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.
