1. Cultures were obtained from 69 cases of ringworm of children in London County Council Schools.
2. Three of them were cases of favus, the parasite in each case being Achoroion Schōnleinii.
3. Microsporums are responsible for most of the ringworm, and were isolated from 54 of the 69 cases, or 78 per cent. Microsporum audouini was found in 70 per cent, of the Microsporum infections; M. lanosum and M. felineum each in one case; and 4 other cultures were obtained, comprising 3 species which have not yet been identified.
4.Endothrix Trichophytons were found in 17 per cent, of the cases and include the species Trichophyton crateriforme, T. sulfureum, T. acuminatum and T. violaceum.
5.A list of the species isolated arranged, according to the new classification of Ota and Langeron, is given.
6.The results are compared with those previously obtained in London by Fox and Blaxall, and Adamson, with which they broadly agree.
