eight wheat varieties some of which were earlier reported to be resistant to pythium arrhennmanes, were inoculated with p. arrhenomanes. inoculation was performed by placing 2-day-old seedlings on the edge of a p. arrhenomanes culture on corn meal agar for 3 h at 25°c. infected seedlings were then transferred to test tubes (9 mm dia.) containing glass beads and 1 ml of sterile water, and in...

Four separate examples have been discussed with the object of showing, first, how the concept of toxic amblyopia is an irrelevant one for modern ophthalmic research. This is the more true since one large category of the classical toxic amblyopias is not toxic at all and further adds to the confusion.

These studies have been made with material with different contents of chlorine, from different manufacture, and-as we can now say in retrospect-with different and unknown contents of toxic impurities. For this reason the toxico...
