Spectroscopic observations of the late stages of a limb flare which occurred on July 20,1961, are presented. Because these observations were made with an achromatic coronagraph, accurate line intensity ratios are possible. The He I and He ii line ratios indicate a recombination-cascade spectrum. Measurements of cbntinuum densities give values around 1010 in the post-flare loop region and 1011 or more in the flare. Ca xv line widths correspond to 4.3 X 100 K. A magnetic loop structure which guides successive surges is studied.
