Cystic swelling.

Photographing small lesions at high magnification can make it difficult for the reader to orientate to the exact location. This issue's photograph shows all the clinical aspects of a cystic swelling on the patient's digit.

Vaccination against feline leukaemia virus using a cell membrane antigen system.

Cats inoculated with live feline lymphoblastoid cells of the FL74 line developed high titres of antibody to feline oncornavirus-associated cell membrane antigen (FOCMA). Eight cats were subsequently challenged with a large dose of feline leukaemia virus (FeLV) of a highly pathogenic strain. All resisted infection while 10 cats given the challenge virus alone became infected. The FeLV produced by FL74 cells was shown to be of extremely low infectivity in cats and in cultured feline cells. Cats inoculated with either FL74 cells or virus purified from them did not become infected. The purified virus did not induce FOCMA antibody in cats not previously exposed to FeLV. The fact that FL74 cells are highly immunogenic, but produce virus of low infectivity, is of value in devising vaccines against FeLV. Cats were also inoculated with FL74 cells which had been inactivated with paraformaldehyde. They developed FOCMA antibody, reaching a peak titre of 256, and no virus could be cultured either from the vaccine preparations or from the tissues of the cats.

The Florida retinal densitometer.

1. In Part I the principles of reflexion densitometry are discussed in relation to the measurements of visual pigments in man.2. In Part II the new Florida densitometer is described in some detail, and records are shown of the instrument's performance with pigment in equilibrium or changed by bleaching.3. With an artificial eye the fluctuations are of the order to be expected from quantum noise and limit the precision of one measurement to 0.0035 of ;double density' which corresponds to some 2% of total pigment.4. Part III treats of the reliability and significance of the measurements in living man. It needs ten repeated measurements to attain the reliability of 1 with the artificial eye.5. The measuring light used bleaches cone pigments by 0.4% in the 6 sec required to make a measurement.6. The interpretation of the measurements is briefly discussed.

Children abandoned in long-stay hospitals.

This study, financed by the Buttle Trust, investigates some aspects of the problems of abandonment of children in hospital, employing a sample of sixty-eight children from six selected hospitals, who meet a given definition of abandonment. Almost a fifth of the total population of children in the hospitals studied meet this definition; about a third of the sample are abandoned early in their lives, and for the remainder, admission itself appears to be a factor in abandonment.
