-2 single case report is given. Thrrc was a distinct lmlsation 01.er the thumb, thenar eminence, the l’rosimal half ctf the index finger, :mtl the :~djaccnt p:~lrn. Pain at times was severe; hlectling was frcqurnt following trauma. Becau,*c of bl~tling antI infection the thurnh anrl for~+nger \VPW amputatctl. I’:tthologir~al examination showed the distal phalanx of thl% thumb and the illiddlc phalanx of the index finger to be permeated by large, thick, anastamosing vascular channt~ls. 111 most c:m2s it was iml)ossiblc to identify the rfs3els as arteries or veins.

A. RI. A. 107: 1697, 1936. Studies were made of the effeet of alternate suction and l~rcssure, of heat, and a combination of the two, on several factors in vascular insu%cieney in the lower extremities. Emphasis is laid on skin temperature readings on the tots and on values for 0, and (JO2 in the blood from the upper part of the saphenous rein of the affected limb. When heat was used, some degree of sweating was usually eft’retetl. When suction and pressure vias used, it was used for one hour, measurements being taken before and after the procedure. Iteasoning from values obtained for the three variables, skin tcmperaturc, 0, sat.uration, and CO,, the authors concluclt~ that the effect of suction and pressure alone is to increase tissue metabolism rathc’r than to increase lrluc~d flow. They base this conclusion mainly on a slightly redmel. art-rage O/Xl, ratio in venous blond under suction alone and on an inereasetl average O,/COz ratio in venous blood rcThey agree with previous authors suiting from reflex vnsotlilatation caused by heat. that heat should be used with suction am1 pressure Itut. belicre t,hat suction atid lmcssure is efYectire by its increasing tissur met.abolism rather than by its increasing I~lOOd flOlT.

Certain subjects exhibit abnormal local and systemic reaction to cold. The local effects on that part of the skin exposed to cold include redness, swelling. anh increased skin temperature on removal. There is flushing of the face, a sharp fall in blood pressure, a rise in pulse rate, a tendency to, or the actual development of, syncope. When a tourniquet is placed on an arm and that hand is placed in cold water, there is no systemic reaction, but one or two minutes after removal of is thr tourniquet the systemic reactions are more severe than when no tourniquet used. In six cold-sensitive subjects the same clinical syndrome was produced bp Analyses of gastric free hydrochloric acid beforc and administration of histamine. after eliciting the response to cold showed differences similar to those found 1b.v in jection of histamine. Attempts to isolate histamine from the blood at the height of a systemic reaction to c.old have been unsuccessful and were ttlso unsuccessful when histamine was injected in quantities sufficient to produce shock. Some of the patients have been susceptible to exposure to cold for many years. Systemic tlesensitization to cold is accomplished successfullr in nlost patients by The authors i,efer to a case in frcqnent short exposure of the hands to cold nater. the literature in which a patient was desensitized to cold I,y administration of histamine.
