✓ The author utilizes autopsy models and normal clinical subjects with and without pneumoencephalography to demonstrate the value of echoencephalography in delineating the position of the aqueduct of Sylvius. Echoes from the dorsum sellae, the anterior wall of the sella turcica, and the aqueduct proved consistently identifiable, while echoencephalographic examination of 25 normal subjects revealed in all instances well-defined aqueduct echoes. Thus the aqueduct echo method may be a diagnostic aid in determination of the anterior-posterior position of the brain stem.

In confirmation of the work of others it has been shown that the principal enzyme in human cerebrospinal fluid that can hydrolyze acetylcholine is true cholinesterase. There is in addition a lesser quantity of pseudocholinesterase. The true cholinesterase, but not the pseudocholinesterase, was found to be significantly increased in the spinal fluids of patients with syphilis, while the pseudocholinesterase, and not the true cholinesterase, was increased in the fluids of patients with either meningitis or poliomyelitis. The true cholinesterase activity was correlated neither with the protein concentration nor with the cell count, while the pseudocholinesterase was correlated with the protein concentration and less significantly with the cell count. When correction was made for the correlation between cell count and protein concentration, the correlation between pseudocholinesterase activity and protein concentration remained statistically significant, but that between pseudocholinesterase and cell count became of dubious significance. In pathological conditions it appears unlikely that either true cholinesterase or pseudocholinesterase is derived from the white cells in the fluid. It is possible that the increased pseudocholinesterase comes from the blood plasma as a result of an increase in the permeability of the "plasma–spinal fluid barrier" and that the increased true cholinesterase comes from the substance of the brain or spinal cord. For the pathological conditions studied, the determination of true and pseudocholinesterase activity of the spinal fluid would be of little value as a diagnostic aid.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
