35. A quantitative study of the lipins o£ bile obtained from a 

 patient with a biliary fistula. Jacob Rosenbloom. Through 

 the kindness of Dr. William Weinberger, of the Lebanon Hospital, 

 there was placed at my disposal 3180 c.c. of human bile obtained 

 from a patient with a biliary fistula. The fluid had the appearance 

 of typical human bile. Its specific gravity was 1.020. The follow- 

 ing data were obtained in a quantitative lipin analysis, the results 

 being expressed in parts per thousand: Water, 970.2; total solids, 

 29.8; cholesterol, 2.61; lecithans, 6.42; fat, 6.85; fatty acids, 1.2; 

 soaps, 2.6. Total lipins, 19.68 (1.97 per cent.).

 partition of nitrogen in urine from a dog. Jacob Rosenbloom

37. A case of allergy to common foods.^^ Oscar M. 

 ScHLOSs. In a boy now 8 years old marked urticarial lesions were 

 caused by the Ingestion of eggs, almonds and oatmeal. The idiosyn- 

 crasy to egg was not congenital but was acquired at some time be- 

 tween the ages of 10 days and 14 months. Symptoms due to the 

 ingestion of oats appeared some time after the child had first eaten 

 oatmeal when he was 22 months old. As far as can be ascertained, 

 the idiosyncrasy to almonds was manifested the first time this food 

 was eaten. 



It was found that cutaneous inoculation of these and certaln 

 related food substances produced an urticarial wheal at the site of 

 inoculation. The cutaneous reaction was produced only by the 

 protein constituents of eggs, almonds and oats. Different proteins 

 from the same source varied in activity, some being incapable of 

 causing a reaction. Some of the active proteins caused Urticaria by 

 mere contact with the unbroken skin. It was possible passively to 

 sensitize guinea-pigs to ovo-mucoid (one of the active proteins from 

 eggs) by intraperitoneal injections of the patient's blood-serum. 

 By feeding ovo-mucoid, in gradually increasing doses, the patient 

 became immune to egg. At the same time immunity to oatmeal 

 and an apparently decreased susceptibility to almonds occurred.
