The only detected transmission at ${\\rm S/N}>5$ is confined to seven narrow spikes in the Ly$\\alpha$ forest, over the redshift range $5.858<z<6.122$, just longward of the wavelength of the onset of the Ly$\\beta$ forest. There is also a possible detection of one further unresolved spike in the Ly$\\beta$ forest at $z=6.854$, with ${\\rm S/N}=4.5$. We also present revised Hubble Space Telescope F814W photometry of the source.
