The effect of hypertonic solution on the spinal fluid pressure is of vital importance from a clinical standpoint, since Weed and McKibben1 show that the cerebrospinal fluid volume could be reduced by intravenous injection of hypertonic solution.

We used various concentrations of NaCl and of glucose. The results were uniform. First, it was demonstrated that hypertonic saline has a definitely toxic effect, which in con...
