THE MICROSCOPE. ii 



two "were always delicate," one suffered from chorea during child- 

 hood. The two remaining cases are more serious ; one is compelled 

 to keep her bed nearly if not quite the whole period, and suffers 

 extreme pain. The other lady suffers much during the first twenty- 

 four hours, sometimes longer. She becomes very pale, and finds 

 much relief in rest. Both of these have serious uterine trouble 

 sufficient in itself to account for these serious attacks. Both are 

 unmarried. 



In support of the last proposition I have only the testimony of 

 others to offer, as I, myself, have never studied the subject micro- 

 scopically ; but the testimony that I shall offer is of far more value 

 than my own would be. Prof. Thomas in the last edition of his 

 work on Gynaecology, says that the best microscopist cannot distin- 

 guish between a true and a false mole. While a student in the Uni- 

 versity of Michigan, Prof. Vaughan informed me that he had 

 received numerous specimens of this nature for examination from 

 young physicians who had gone out from the University ; but 

 declared that he, as yet, had never been able to differentiate between 

 so-called true and false moles. I shall leave Prof. Stowell to speak 

 for himself, as he can do so far better than I can speak for him. 



In conclusion I shall give as my opinion that if such persons as 

 the above are in doubt upon this vexed question, it would be at least 

 well for physicians to be somewhat cautious in diagnosing abortion 

 from " signs and symptoms," even should they see tvell defined blood- 

 vessels and what resemble the villi of the chorion. Especially should 

 caution be observed if the patient is an unmarried lady. 



[Dr. Owens has sent me several specimens to examine, and they 

 are well represented by the figure given above. The blood-vessels 

 could be readily separated from the mass by careful teasing and 

 washing. C. H. S.] 



A CASE OF OXALURIA. 



BY E. O. BENNETT, M. D. 



THERE are many medical cases coming under a physician's 

 observation in which the microscope is an indispensable aid to 

 a proper diagnosis. Especially is this true when digestion and
