A simple probabilistic model is proposed f o r the collision and d erailment experience for freight t r a i n s of U.S. Class I railways. By means of this model, asymptotic confidence intervals are constructed f o r the probability p e r mile of a derailment accident as a function of t r a i n speed

✦ Synopsis
Gradual osmotic hemolysis of camel erythrocytes was observed by means of phase contrast microscopy and recorded by microcinematographic methods. It was found that the normal ovoid erythrocytes become spherical when the solution surrounding the erythrocytes is diluted ionically, and they swell to 240% of the initial volume. After hemolysis the erythrocyte membranes (ghosts) revert to their original oval form.
Comparative studies of osmotic fragility tests on red blood cells of growing and adult camels showed the presence of two distinct cell populations in growing camels. One corresponds to the adult blood. The second cell type is more resistant to osmotic pressure and is found only in the young camel.
