Abstract of the Proceedings, July 28th, 1909. — Mr. Kesteven ex- 

 hibited sections of the cervical cord of a dog, and mesial, sagittal sections of 

 the brain oi Hyla oio'ea treated as follows — 1) fixed in absolute alcohol; 

 2) cleared in cedar oil; 3) embedded in paraffin; 4) cut, and mounted by the 

 water method; 5) mordanted in Müller solution at 45°C. , 48 to 76 hours; 

 6) stained in 1% haematoxylin and 2% acetic acid, 2-4 hours; 7) differ- 

 entiated in a) 2h% potassium permanganate, bj 2% oxalic acid -\- 2% 

 potassium sulphite, equal parts; 8) washed in a weak alkaline solution. Al- 

 though the staining is a modified "Weigert-Pall," the results are completely 

 difi"erent, axis-cylinders, nerve-cells (tyroid substance), and the nuclei of all 

 cells staining black or brown, all other tissue remaining quite unstained. The 

 advantages of the new stain are that the difi"erentiation does not take place 

 rapidly, so that one may successfully treat a large series on a slide; and the 

 whole process may be completed in five or six days. Since the fixation is by 

 absolute alcohol, the method is limited to small brains or small pieces of 

 tissue, but it should prove extremely useful for studying these. Since the 

 pictures are black on a white background, they are admirably adapted for 

 photographing. — 1) New Australian Lepidoptera belonging to the

 M.A., F.E.S. — The genus Diphlebia contains the only Australian representa- 

 tives of the family Calopterygidae. The discovery of the larva is of great 

 importance to ontogenists. The ova were found in the tissue of water-weed 

 one foot below water, the female having deposited them by descending the 

 reed under protection of an air-film Larvae were successfully hatched out
