Naturevolume 140page111 (1937) | Download Citation



EVIDENCE confirming the description1 by Bawden et al. of the shape of the tobacco mosaic virus particle appears in Best's recent photograph2 of virus protein forming long threads after it has been precipitated from solution. Further evidence that virus particles, even in dilute solutions, may form chain aggregates is obtained from experiments on the relation between dilution of virus and number of infections caused.
