Herodiones showed eight cases of anemia, five herons, one bittern and two storks. Parasites are noted in only three examples, herons, and it is noteworthy that these all had flukes in the proventricle or intestine; one also had ascarids in the proventricle. Two of this order suffered with long standing inflammation following bone injuries. Perhaps the outstanding features of this order are the erythrocytic picture and the condition of the spleen. The red blood cells seem very fragile or soft, for one often encounters in their fresh or stained preparation vacuoles or rifts in the protoplasm surrounding the nucleus. At first we thought these were hemosporidia, but repeated attempts at their coloration and the absence of pigment granules seem to warrant an assumption that they are artefacts. In five of the seven instances there is very definite evidence of present or past activity of the spleen. We have not always considered it sufficiently prominent to call it a splenitis, but follicular activity is commonly discoverable, and two cases of definite fibrosis are recorded. The sun bittern (_Eurypyga helias_) showed a chronic interstitial nephritis in the atrophic stage. No other of the wading birds showed secondary anemia. There are seven cases among the pigeons (Columbæ) where anemic tissues attracted our attention. Three were associated with osteomalacia, in one of which the marrow picture was that of an aplastic form being everywhere pale and flabby without cells under the microscope; it is further interesting in this case that there was a distinct but ineffectual attempt at bony regeneration by the periosteum. In another case, this time brought to death by an enteritis and cloudy swelling of the viscera, the marrow was hyperplastic and red, there being activity in the basic staining areas of the head and in the shafts. (Notes of the third case scanty.) None of the seven cases seems to have been associated with animal parasitism; one had tuberculosis. The other cases are obscure and not definitely connected with other pathology. Ten more cases of anemia were scattered among seven orders. There is nothing striking or even individual about them worthy of special mention. SUMMARY OF SECONDARY ANEMIA.
