WELCKER, ON SARCINA. 1G7 



parture of the patient, "was afforded for further experiments 

 than those I shall now mention, for its determination. 



The author then proceeds to detail some experiments, in 

 which he injected some of the urine, containing sarcina, into 

 the bladder of a rabbit and of a dog, without any result. 

 Its introduction also into the stomach of the former animal, 

 with its food, was also unattended with any result ; no 

 trace of the sarcina being found in either case, either in the 

 urine during life, or in the organs after death. 



Some observations are then made on the mode of develop- 

 ment and systematic position of the Sarcina; but, as these 

 do not appear to contain anything of importance, we pass 

 them over, and conclude with the following list of queries, 

 which are suggested by Dr. Welckcr, as demanding atten- 

 tion. 



1 . Does the Sarcina urince always exhibit the small dimen- 

 sions above indicated, of the isolated cells, as well as of the 

 entire bundle ? 



2. Has the Sarcina found in other situations also, as in the 

 lungs, for instance, the same or very similar characters ? 



3. Is the transplantation of Sarcina urince into the 

 stomach always without result? Or, does it, under these 

 circumstances, retain its peculiar characters, or assume those 

 of Sarcina ventriculi ? 



4. What is the result of the introduction of Sarcina 

 ventriculi into the urinary bladder? 



5. Is Sarcina urince never, or at any rate so rarely accom- 

 panied by Sarcina ventriculi, that even in this respect the 

 two forms appear to be independent of each other? 



6. Is the urinary bladder the only habitat of Sarcina 

 urince ; or, is it also to be found in the pelvis of the kidney 

 and the tubuli uriniferi ? 



7. Is the presence of sarcina in the urine accom- 

 panied with any special morbid condition of the uro-genital 

 system ? 



8. In case the last question should be answered in the 

 affirmative, in what way does the infection with Sarcina 

 urince take place ? 



9. What means have we, and especially by injection, for 

 the destruction of the Sarcina ?
