hematuria rather than hemoglobinuria ; among these we must espe- 

 cially mention : the coniferous buds, crowfoot, rush, water pepper, 

 mercurialis, euphorbia, hemlock, etc. Several observations establish 

 very clearly the pathogenic influence of the alder (elecampane) 

 (Alnus alpina, A. viridisy A. incana, A. alnohetula). It is doubtful 

 whether sedges, bulrushes, flowering rushes, and the horse-tails 

 grasses are able to produce hematuria, as stated by Spinola. 



2. The theory of the rheumatismal nature (rheumatismal or myo- 

 genic hemoglobinemia) of this disease has many adherents. Among 

 the facts invoked in its favor, we must first mention the frequency 

 of the disease in the spring, when ttie bovines that have been kept 

 in stables are led to cold and damp pastures, and its infrequency 

 when pasturing of the animals is delayed. At the stable, the pass- 

 ing of blood may be produced by the ingestion of icy fountain 

 water (Ryschner). It appears sometimes when the animals drink 

 at very cold mountain springs (Ziindel). In Gallicia, says Roll, 

 it exists mainly in the cold and mountainous regions. Dotter de- 

 clares himself clearly in support of the rheumatismal nature of the 

 disease. Utz,^ who has observed it in the stable, attributes it espe- 

 cially to chilliness during the cold spells. According to Hink, 

 "rouge de pâturage,'' which is very common in the Black Forest, 

 is a hemoglobinuria similar to black strangury of the horse. Fre- 

 quent upon young subjects, at the time they are led to pasture for the 

 first time, it would be produced by cold, by rapid ingestion of cold 

 or damp fodder, and also by violent and unaccustomed exertions. 

 In an establishment " for the cure of disease by milk diet," Saur ^ 

 saw a milch cow which was well fed, overcome with general rheu- 

 matism and blood emission after a simple cold. All these facts and 

 the analogy of certain clinical symptoms observed in hemoglobi- 

 nuria of the ox with that of the horse (stifl*ness of the hind quarters, 

 sensitiveness to pressure of the lumbar region), indicate, in our 

 opinion, a very close relationship between these two diseases. 



Symptoms. Most modern authors have confounded the symp- 

 toms of renal hematuria with those of true hemoglobinuria. We 

 have been obliged to guide ourselves according to the descriptions 

 of older authors (Spinola, Stockfleth, Gerlach), which are quite 

 difl'erent from those found in some of the more modern publica- 

 tions. 



According to these pathologists, the symptoms consist principally
