The occurrence of casts in the urine following magnesium sul- 

 phate ether anesthesia (Meltzer). 



By Charles H. Peck (by invitation). 



[From The Roosevelt Hospital, New York City.] 



The report relates to the occurrence of casts in the urine 

 following operation under magnesium sulphate-ether anesthesia, 

 in a series of five cases observed by Drs. Meltzer and Peck at the 

 Roosevelt Hospital. 



Three cases showed hyaline casts in the urine which dis- 

 appeared after 48 hours and did not reappear. One of the three 

 showed a faint trace of albumin; the other two, no albumin. 



Two cases showed hyaline and granular casts and a trace of 

 albumin, one persisting for six days, one for two days or more, 

 being normal on the fifth day. 



None of the cases showed any later evidence of kidney irrita- 

 tion. In all of the cases magnesium could be demonstrated in the 

 urine for several days. In none of the cases were casts present in 

 the urine before operation.

The experimental production of an early stage of extrauterine 



pregnancy 



By Leo Loeb. 



[Barnard Free Skin and Cancer Hospital, St. Louis, Mo.] 



In former experiments I had shown that it is apparently im- 

 possible to produce experimentally an extrauterine pregnancy in 

 the guinea pig. 1 Neither ligation of the fallopian tubes at the 

 juncture with the uterus, nor incision into the tubes or wall of 

 the uterus at various periods of the sexual cycle led to the develop- 

 ment of an extrauterine pregnancy. In another series of experi-
