of a thick consistence and of a turbid appearance ; it is rarely suppressed, but 

 whenever this happens, an angular calculus as large as a bean is voided per ure- 

 thram ; and what before happened only occasionally, now takes place every day, 

 viz. in the morning, dum urinandi motus urget, part of the urine first come* 

 away per urethram, and almost immediately afterwards another quantity (to the 

 amount of 3 or 4 oz.) is discharged by vomiting, of the same colour, consist- 

 ence, smell, and (according to the patient's account) of the same taste (a taste 

 creating much nausea) with that discharged from the bladder. The abdomen 

 continues tumid ; and there is not only in the left hypochondrium (as before) a 

 hardness, accompanied with a sound as of stones rubbing one against another, 

 but the same sound is perceived in the whole right hypochondrium also ; and 

 the patient moreover complains of great pain about the hypogastrium. She has 

 a tolerable appetite ; her usual drink consists of a decoction of the radix gly- 

 cyrrhizae et graminis with barley, to which is occasionally added a small quan- 

 tity of some light wine. Last year, on the 12th of Dec. a gangrene, as large 

 as the palm of the hand, showed itself on the right leg. This gave way to 

 the remedies employed against it. She has since been affected with angina 

 notha, accompanied with a hemorrhage from the fauces ; for the removal of 

 which bleeding in the foot and clysters were resorted to. On the 20th of Feb. 

 she had natural evacuations downwards ; but on the 23d she had not only eva- 

 cuations by stool, but also brought away part of the oily clyster by vomiting, 

 but without any calculi. [Here the autlior terminates the history of this case 

 for the present.] 



In the remaining part of this communication, after mentioning various in- 

 stances of the formation of calculi in other parts of the body, besides the kid- 

 neys and bladder, the author details the result of his chemical examination fo 

 these stones ; and concludes with reflections on the manner of their production, 

 and with a rationale of the concomitant symptom?. 



With regard to his chemical examination,* Dr. Konig states that, 1. In 

 trying to dissolve them, he found that on pouring upon them sp. sulphuris, 

 vitrioli, acetique, some effervescence was produced, especially in those which 

 had been discharged from the stomach, and which were of a looser and friable 

 texture; but that this soon ceased, and that no solution could be effected.- 

 Sp. salis ammoniaci had no action whatever upon them ; but they were com. 

 pletely dissolved by the sp. nitri acidus. 



2. By distillation there was obtained from those calculi which had been voided 

 by the oesophagus a small quantity of volatile salt, volatile spirit and water 



♦ A further examination of these calculi by Dr. Slare is inserted in the following N° of these 

 Transactions.
