492 UTERUS, BY DR. R. CHROBAK. 



tend to the plexus pampiniformis, in order to meet with the 

 lymphatic glands of the lumbar region, whilst those arising 

 from the cervix run to the lymphatic glands of the true 

 pelvis. The lymphatics in the interior of the uterus are 

 almost unknown. 



Hjalmar Lindgren describes the lymphatics in the collum 

 as forming arches, from which csecal processes with sinuous 

 margins extend towards the epithelium. 



METHODS OF RESEARCH. 



The coarse fibrillation of the uterus is best studied in the 

 pregnant uterus, either in the fresh state, or hardened to some 

 extent in alcohol, or macerated for a little while in a warmed 

 mixture of 1 vol. of hydrochloric acid and 90 vols. of alcohol. 

 In order to make good sections, the alcoholic preparations may 

 be dried in air, or after previous boiling in dilute wood 

 vinegar. 



For the purpose of isolating the muscular fibres, very 

 diluted solutions of chromic acid, containing from O'l to O'Ol per 

 cent., may be employed, or solutions of bichromate of potash, 

 iodized serum, potash lye, or acetic acid containing one to two per 

 cent, ; twenty per cent, solutions of nitric acid ; Moleschott's fluid ; 

 a one- half per cent, solution of nitric acid heated to the boiling 

 point ; wood vinegar alone, or this mingled with glycerine. 



To effect the hardening requisite to display the epithelium 

 and nerves, chromic acid, bichromate of potash, alternately 

 applied or mingled together, Miiller's fluid, and freezing, are 

 well adapted ; but for the finest branches of the nerves the 

 wood vinegar in glycerine is still the best. 



As colouring agents, carmine, anilin, picric acid, chloride of 

 palladium, chloride of gold, may be used. 



But by far the most important is the investigation of 

 preparations as fresh as possible, and merely moistened with 

 solution of albumen or iodized serum.
