A new method of determining velocities in transparent and opaque liquids using ultrasonic frequencies over a wide range has been described. Results obtained for a number of organic and inorganic liquids are given. They compare well with values reported earlier in the literature. Only a small quantity of 0·25 c.c. is all that is required and hence the method is particularly suitable for liquids available in very small quantities. The possibility of extending this method for study of dispersion in a variety of liquids is envisaged.

The principle and the experimental details of the new method of determining ultrasonic velocities in transparent liquids along with a brief description of the crystal holder designed to suit this method are given. Ultrasonic velocities determined for about ten common liquids are tabulated along with those obtained previously by different methods. The main features of this method are briefly discussed.
