The study area Burutu lies within the transitional environment of the Niger delta. The area is sectioned by a compact network of rivers and creeks, which maintain a fragile but dynamic balance between saline, estuarine and freshwater surface bodies. Twenty direct current resistivity soundings were carried out to provide adequate information on the spatial lithological variation and groundwater conditions in Burutu. Resistivity contrasts and water analysis were used as a means of characterizing probable lithology and water type present within the pore spaces of aquiferous units. The results revealed spatial development of the aquifer architectural facies that follows a trend of mostly sand with little clay in the south to sand with abundant of clayey facies in the north near the Forcados River. The groundwater conditions indicated that salty/brackish water constituting about 4 % of water present was confined to the bank of the Forcados River and extend laterally landwards to about 120 m. Further away from the river bank, the water was mostly poor to good quality freshwater. The depth to the freshwater constituting about 96 % groundwater present varied from about 49.0 – 63.3 m near the Forcados River and became as shallow as 1.6 m in inland areas.

Professor Philip D. Curtin of the University of Wisconsin has written to correct certain points made by Dr John E. Flint in his review of The Small Brave City State: A History of Nembe-Brass in the Niger Delta, by Ebiegberi Joe Alagoa (Journal, VI, 2(1965), 248). He points out that Mr Alagoa's book was a preliminary study in local history which was written in Nigeria while Mr Alagoa was in the service of the National Archives there. Since then, Dr Alagoa has completed a Ph.D. thesis at the University of Wisconsin, but it is not yet published. Dr Flint also accepts Professor Curtin's correction of his observation about ‘the difficulty of pursuing research in such a topic [of African history] from a base in the U.S.A.’ This would not, in any case, apply to the University of Wisconsin, since Wisconsin normally requires Ph.D. candidates in African history to conduct their research in Africa and in appropriate European archives.Dr Robert Rotberg of Harvard and Herr Hans-Jürgen Greschat of the Philipps-Universität, Marburg, have pointed out an inaccurate compression of events in my article on ‘Witnesses and Watchtower in the Rhodesias and Nyasaland’. As some of your readers may come to accept my chronology of the imprisonment of Elliott Kenani Kamwana Chirwa (p. 92, n.4), perhaps I should set matters straight. I said that he was arrested, deported to Mauritius in June 1909, released by March 1914 and re-deported around December 1916. In fact, Kamwana was given the choice of restriction to Nyasaland's Southern Province or removal to South Africa in 1909. He seems to have returned in 1910, was sent back to South Africa, which this time refused him entry, and next went to Chinde in Mozambique, where he stayed until the outbreak of war, when the Portuguese repatriated him. The British once more detained him in the Mlanje District and after the Chilembwe revolt sent Kamwana and others back to Mauritius for about a year and then to the Seychelles until 1937. These additional details concerning his peregrinations are interesting in themselves and I thank my two correspondents for supplying them.

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.

Purpose This preliminary study examined whether speech profiles exist for adults with hereditary ataxia based on 2 competing frameworks: a pattern of instability/inflexibility or a pattern of differential subsystem involvement. Method Four dysarthria experts rated the speech samples of 8 adults with dysarthria from hereditary ataxia using visual analog scales and presence/severity rating scales of speech characteristics. Speaking tasks included diadochokinetics, sustained phonation, and a monologue. Results Speech profiles aligned with the instability/inflexibility framework, with the pattern of instability being the most common. Speech profiles did not emerge for the majority of speakers using the differential subsystem framework. Conclusions The findings extend previous research on pure ataxic dysarthria and suggest a possible framework for understanding the speech heterogeneity associated with the ataxias. The predominance of the instability profile is consistent with the notion of impaired feedforward control in speakers with cerebellar disruption.
