 Tr. benzoin without resorcin has very little action on the eruption. I generally apply resorcin dissolved in Tr. benzoin once or twice daily to the afiected parts. If the whole body be affected, one half is painted on one day ; next day the other half is treated, and so on alternately. This treatment must be continued for several weeks, and once or twice a week the patient is given a very hot bath and is scrubbed all over with sand soap. In this way I have treated five cases, all of whom left the clinic apparently cured. After four months I had an opportunity of seeing three of them again. Two remained well ; in one, two small patches had reappeared on the right shoulder. So far, I have not observed symptoms of absorption ; in fact, the patient who showed signs of absorption after chrysa- robin stood the resorcin treatment well. It is always prudent, however, to proceed with care at first, as it is well known that individuals may be met with — though rarely — showing idiosyncracy for resorcin.

In conclusion, it would appear from these researches that the best treatment for Tinea imhricata isLinimentum iodi., as suggested by Manson, or resorcin dissolved in Tr. benzoin, as suggested by myself.

Tinea Intersecta.

I first described this afi'ection at the International Congress of Dermatology held in New York, September, 1907, when I based my description of the disease on two cases. Later, I have come across several more instances among natives of Ceylon — Singhalese and Tamil.

The eruption begins with small oval, or roundish, slightly elevated itching patches, generally situated on the arms, legs, chest and back. The margins of these dark spots are slightly elevated and dotted with minute dark papules. At first the patches are dark brown in colour — darker than
