the action of front and back braking on a motor-car. 

 The latter arrests only the motion of translation 

 of the car ; in the former the brake also affects 

 the car's movement of rotation round the vertical.

Royal Society of New South Wales, August I. — 

 Mr. R. H. Cambage, president, in the chair. — S. Dodd : 

 Cancer of the ear of sheep : a contribution to the 

 knowledge of chronic irritation as a secondary factor 

 in the causation of cancer in the lower animals. 

 Cancer of the ear is rather common in sheep in 

 Australia. Ears from 47 sheep so affected were 

 examined microscopically : 32 were found to be 

 definitely epitheliomatous ; 9 showed a condition 

 of chronic inflammation only, and 6 were in a pre- 

 cancerous stage. An affected sheep received alive 

 was kept under observation ; five months later the 

 middle cervical gland showed signs of enlargement. 

 Six months after receipt the sheep was killed and the 

 autopsy showed practically the whole of the ear to 

 be carcinomatous. The facts presented support the 

 view that a chronic irritation, naturally occurring, 

 may lead to cancer in the lower animals. — L. S. Cash 

 and C. E. Fawsitt : The estimation of cineol in 

 essential oils by the Coclcing process. The method 

 consists in mixing the oil with o-cresol in certain 

 fixed proportions and finding the freezing point of 

 the mixture. The method is more easily carried out 

 than any of the other methods usually employed for 

 estimating cineol. The results are at least as accurate 

 as those obtained in other ways and the accuracy can 

 be increased by taking into consideration the density 

 of the oil. — H. J. Hynes : Investigations by the late 

 C. O. Hamblin into the Helminthosporium disease 

 of wheat. Pathogenicity tests indicated that the 

 strain of Helminthosporium isolated from Marshall's 

 No. 3 wheat at Cowra in November 1920 is a true 

 parasite of the wheat plant, capable of causing a 

 " Foot-Rot " condition and also lesions on the leaves. 

 Seed from diseased plants when sown gave rise to 

 healthy plants. The " Foot-Rot " condition was 

 observed at Cowra in 1921 on 150 different wheat 

 varieties. Spores of Helminthosporium were found 

 on Slav rye, skinless barley, Hordeum murinum, 

 Brotnus inermis, B. sterilis, and spear grass.
