may be at first temporary from excitement and later more con- 

 tinuous by reason of the greater compression of the neck by the 

 enlarged and indurated prostate. With the advance of the dis- 

 ease the urine shows abundance of triple phosphates,- and be- 

 comes ammoniacal and foetid. A dark or bloody color of the dis- 

 charge and the presence of crystals suggest calculus. 



An accurate diagnosis can only be had by rectal examination. 

 The great enlargement of the prostate, in the absence of heat 

 and tenderness is characteristic. Enlargement is usually uni- 

 form, though it may be concentrated on the right, left or central 

 lobe. The passage of the catheter may be obstructed, but is- not 

 specially painful at the prostatic region as in prostatitis. From 

 vesical calculus it is distinguished by the fixity of the swelling 

 on the neck of the bladder as contrasted with the mobility of the 

 stone inside that half- filled organ. From stricture it is differen- 

 tiated by the fact that the obstruction offered to the catheter and 

 the swelling of the prostate exactly correspond in position, that 

 the stream is lessened in force rather than simply reduced in size, 

 and that the history of the case shows no antecedent cause for 

 stricture. 



Treatment. This has been considered as mainly palliative. 

 Special care of the general health and above all of the diet which 

 should be moderate, farinaceous and laxative, protection against 

 cold and wet, the correcting of any coexisting trouble of the 

 urinary or generative organs, and the removal from all sources of 

 generative excitement are important elements. Occasional small 

 doses of Epsom or Glauber salts in draught or enema obviate 

 rectal hypersemia. Ergot, potassium iodide internally, and iodine 

 or mercurial ointment to the perineum have had little good effect. 

 Mbller claims to have secured improvement from the injection 

 into the prostate a.t intervals of fourteen days, of a solution of two 

 parts each of tincture of iodine and iodide of potassium, and sixty 

 parts of distilled water. A small hypodermic syringe is used and 

 the injection is made through the rectum directly into the sub- 

 stance of the prostate. Glass has adopted the recent surgical 

 alternative of castration, with the result of marked relief from the 

 active symptoms in a number of cases, but with a more rapid 

 advance through emaciation and marasmus to death in three or 

 four weeks in others. We would suggest a careful antiseptic
