    Notes: Abstract Somatic embryogenesis was achieved in callus cultures dervied from 40-day-old semimature zygotic embryos ofDalbergia sissoo on semi-solid Murashige and Skoog (MS) salts and vitamins supplemented with 0.46–1.16 μM kinetin, 6.78–9.04 μM 2,4-dichlorophenoxy acetic acid (2,4-D) and 30 g/1 sucrose. Somatic embryos proliferated rapidly by secondary somatic embryogenesis after transfer to half-strength basal MS medium supplemented with 0.46-1.16 μM kinetin and 6.78–9.04 μM 2,4-D with 2% (w/v) sucrose. The light-green somatic embryos germinated on half-strength MS salts and vitamins supplemented with 0.5 mg/1 abscisic acid and 2% (w/v) sucrose. The developmental stages of somatic embryogenesis were studied by light and scanning electron microscopy.

    Notes: One of the main hazards associated with the use of hydraulic fluids is the accidental release of hydraulic fluid near to a source of ignition. Several tests simulating this hazard have been developed but, in the opinion of the authors, none fulfils all the scriterla required of a flammability test. A new form of test has been developed. A test chamber is ventilated by a smooth flow of air; the hydraulic fluid under test is sprayed into the test chamber and ignited. The temperature rise in the gases leaving the stack and the radiation from the flame are measured at a specified time and from these measurements the heat output of the flame is estimated. Different fluids are then compared on the basis of their heat output values and data are presented in the paper for a variety of fluids.
