A report of nine cases of lymphosarcoma of the bowel in childhood is presented, together with a review of the literature. Until recently, the prognosis of this condition has been poor,but it is hoped that modern treatment with surgery, radiotherapy and multiple cytotoxic drugs given in high dosage over a two-year period will result in improved results.

An examination of occupational injuries in Australia during the 1960's is made. It is shown that the incidence of occupational injuries decreased by about 12% during the decade and that occupational injuries now approximate 200,000 per annum. Although there are approximately six injuries to men for every one to women,types and sites of occupational injury do not differ between the sexes. ⋯ The age distribution for serious injuries (incurring an absence from work of more than 28 days) differs markedly from the equivalent distributions for minor occupational and all road injuries in that the third, fourth, fifth, and sixth decades of life each contribute about 20% of this total. The customary heavy over-representation of young males is notably absent. "Passive" countermeasures (those that are behaviour-independent) are held to have been differentially more successful than those that are "active" (those that require active cooperation). Examples are given.

An analysis of patients presenting with headache shows that in very few cases is the headache related to refractive error. Similarly in presbyopia and hypermetropia headaches are infrequent. A significant proportion (up to 50%) of those patients presenting with a close relationship of headache to accommodation difficulty can be helped by glasses. It is postulated that ciliary muscle contraction per se is effortless and symptomless and that any headaches produced are due to associated contraction of the scalp muscles.
