236. We know that the old mountains are gradually being washed away by the rain, and that new mountain ridges rise from time to time as the result of tectonic activity, but all these changes are still only the changes of the solid crust of our globe. It is not, however, difficult to see that there must have been a time when no such solid crust existed at all and when our Earth was a glowing globe of melted rocks.

Moreover, the high incidence of acute myocardial infarction in this group adds further diagnostic difficulty. The present triad allows this difficult differential diagnosis to be made precisely even in geri­atric patients with preexisting heart disease.

239. The results of this measurement for the two GaAs junc­tions are shown in Figure 12. Q is plotted as a function of photon energy. The response tends to saturation at the higher photon energies. By extrapolating the data toward the apparent satura­tion values, the diffusion lengths in the skin are calculated to be 0.5 and 0.6. The lifetime is thus 10-10 sec, if one assumes a diffu­sion constant of 25 cm2/sec.

240. The active antigenic fraction, in spite of revealing many properties similar to viruses, was not infectious. It was believed to be an autocatalytic cellular component with proliferative activi­ty. In his review Hauschka discussed the possibility that some isoantigenic components of the Brown-Реагсе sarcoma may have influenced experimental results of Kidd and his collaborators.

241. By reducing circuit operating temperature below normal ambients, and by holding it constant, excellent stability was ob­tained.

242. Besides being a function of speed, the output of the drag cup generator is also a function of the voltage applied to the pri­mary winding. Whereas this is not a disadvantage in the usual sense, it does require careful regulation of the applied voltage. Furthermore, the fact that the output is an a-c voltage can cause additional components to be used and time delays to occur in certain application.

243. In the fourth case, diagnosed as probable membranous glomerulonephritis, the pattern of fluorescense observed in the treated kidney sections was quite different from the patterns de­scribed in the previous three cases. Sections exposed to conjuga­ted anti-human globulin showed specific fluorescence in short thin segments of glomerular capillary walls. This was noted to be con­fined almost entirely to peripheral portions of the glomeruli.
