Very little urine was voided, but it presented a most extraordinary
character, being dark brown and very thick; it contained no blood
corpuscles, but a considerable amount of haemoglobine (the coloring
matter of the corpuscles), which was recognized by the absorption
bands it gave in the spectroscope. The kidneys were uniformly bluish
black. The blood had a dirty brownish red tint, and contained an
abundance of _detritus_ of red corpuscles.
This case points out once more that photographers cannot use too much
prudence in dealing with chemical products which are in daily use by
them, and the noxious properties of which, they are apt to
forget.--_Photo News._
