On the basis of equations derived. by the author, a nomograph was plotted by means of which one can determine rapidly the respiratory quotient and the 02 equivalent of venti- lation. Another nomograph was devised for the determination of the corrective fac,tor for the ventilation volume. Amethod is proposed for the determination of the initial 0, content in a gas mixture kept in a rubber bag for several days or hours by4using a relationship between the initial and final content of 0 and CO that has been derived by the author.

To avoid the inconvenience of pinning in relatively inaccessible regions, the authors propose using Co-60 needles with higher linear activities at one or both ends than at their middle part. The authors obtained such needles by placing cobalt-nickel pins with different linear activity in steel filters for the Co-60 needles. The distribution of the dose around the ordi- nary and. the modified single needle, and from implants with such needles, Is illustreted with equidensity curves. Using the modified needles gives a suit- able diEtribution of the dose in the implanted region, employing only parallel 1/2 BULGARIA 'RICHTER, J., PENCHEV, P.; Institute of Biology and Medicine (Direo- tor Pro:e.'
