16. As a preliminary to starting the more detailed portion of my report I append a tabular statement of schedule (No. 1) in which form I have endeavoured to afford a simple means of reference to the principal animals examined Where I have in the country. by me blood specimens taken occasion to make subsequent reference to any of them I shall designate them by their distinguishing number. It will be seen that these cases became what I have already referred to as my experimental animals, certain of which are given one or more different numbers to distinguish the different experiments upon them.

17. At Warri three horses were examined. The state of hæmoglobin in their blood was respectively 90, 60, and 80-90. The one at 60 was found to be infected with trypanosomiasis. At Asaba three horses were examined, two being positive and one negative. One of the positive or sick horses showed hæmoglobin at 60, the other at 70. The healthy horse showed hæmoglobin at 90, or practically normal. At Oka one pony was found to be negative, with hæmoglobin at 70, and blood dis- tortions were noticed. Another pony twice examined at Asaba was negative with hæmoglobin at 90. In one pony at Idah no trypanosomes were found, his blood was negative, but showed changes, and symptoms of epizootic lymphangitis were noticed. Three more at the same place were negative.

At Warri eight oxen were examined, of which one was positive with hæmoglobin at 70, and seven were negative with hæmoglobin at 80 to 90. One cow and one bull at Onitsha were found to be negative, the latter showing hæmoglobin at 90. Seven cattle at Ijali were found to be negative; the state of hæmoglobin At Onitsha, of shown was respectively one at 70, four at 80, and two at 80-90. seven oxen, three were found to be infected with trypanosomiasis with hemoglobin at 70, and four were negative with hæmoglobin at 80. Three Government oxen were examined at the experimental farm at Akpaka. They were found to be per- teetly healthy, and were later on inoculated with blood from an ox at Onitsha suffering from trypanosomiasis. These three animals were kept under observa- tion as experimental case, the details and results of which will be found under my Two oxen observations on the experimental treatment of trypanosomiasis. examined at Idah were negative as regards trypanosomiasis, the hæmoglobin in their blood stood at 70 and blood changes were noticed. Two cows at the same place, with hemoglobin at 90 in one and 100 in the other, were both negative. Also at Idah five other cattle examined were all negative, with the exception of one with hæmoglobin at 70 and suffering from trypanosomiasis. One cow at Onitsha was found with hæmoglobin down to 40. At Newi, out of four cattle one was found to be positive and three negative.

Of seven goats and two sheep at Onitsha, one sheep and one goat were gosta. positive, with hæmoglobin at 70 and 80 respectively. The remainder, which were negative, showed hæmoglobin at 80. At Ijali nine sheep were examined, one being positive, with hæmoglobin at 70, and eight negative, of which latter the hæmoglobin of five stood at 80 and of two at 80-90. In the town of Onitsha, out of nine sheep and five goats, two sheep and one goat were positive, the hæmoglobin of the sheep The remaining seven sheep and standing at 60, and that of the goat at 80. four goats averaged hæmoglobin at 80. Four more sheep were examined at Onitsha, one being found positive with hæmoglobin at 70 and three negative, with hæmoglobin of two of them at 80 and one at 70. The one at 70 also showed blood distortions. At the same place two more sheep showed negative with hæmoglobin at 80. Nine goats and two sheep at Idah gave a result showing two of the goats positive and seven negative, with both sheep negative. The hæmoglobin in the two positive goats was at 60 and the remainder at 80, while the hemoglobin of the two negative sheep stood at 80. On another occasion five Idah sheep and two goats showed one sheep positive, with hæmoglobin at 70 and blood distortions, and four sheep negative, with Five more hæmoglobin at 70, and one negative with hæmoglobin at 80. sheep and one goat at Idah showed three positive sheep, with divi- sional forms of trypanosomiasis in two, and with hæmoglobin of all three at 70. The two negative sheep had hæmoglobin at 80, with blood distortions in one of them. The goat was positive and also showed divisional forms, with hæmo- A small island in the middle of the Niger opposite Idah Station globin at 70. was visited, and the result showed two sheep and one goat negative, with hæmo- Of these, one was found to globin at 90.

Six goats were all negative, five with hæmoglobin at 90 and one at 70, with many distortions. Five sheep were examined at Onitsha, of which two were positive and three negative. The hæmoglobin of the two posi- tive sheep stood at 40 and that of the negative sheep at 70. Besides this two goats showed negative, both with hæmoglobin at 80. Four more sheep at Onitsha showed one positive, with hæmoglobin at 60, and the other three negative, with hæmoglobin at 80. At Newi, of nine goats, one was positive, with hæmoglobin at 70, and eight were negative, with hæmoglobin at 80.

The general observations of Lagos horses showed that the most prevalent diseases are epizootic lymphangitis and Lagos horse sick- ness. Four out of the 13 horses examined showed hæmoglobin below normal. Ibadan seven horses were examined and two donkeys, out of which only four horses showed a normal state of hæmoglobin. Out of twenty-four horses at Oshogbo, 18 showed a low state of hæmoglobin. Seventeen donkeys also were examined at At Oyo 11 horses were examined, two only being this town, four being positive. normal as regards hæmoglobin. Trypanosomes were scarce, poikilocytosis was seen in two, punctiform cells (few) in one, and one showed blood distortions.

examined at Cattle. 21. Of up-country cattle imported for slaughter 14 were · Oshogbo and Oyo. Of these only three showed normal hæmoglobin; punctiform cells were detected in one, and poikilocytosis in two. Country-bred cattle were examined at Ebute Metta, Ibadan, Oshogbo, and Oyo, to the number of one hundred and eleven, nineteen only showing normal hæmoglobin. These were to a certain extent animals selected as not appearing quite healthy, from any herds available. some of which numbered from 150 to 200 head of cattle. A portion of them, how- ever, were taken indiscriminately, and it might be gauged roughly that the results shown are a fairly correct average. Trypanosomes were found everywhere, but they were fairly scarce in any individual blood smear examined. It will be observed from a reference to the tabulated statements appended (Nos. 2, 3, 4 and 5) that poikilocytosis, punctiform cells, and various forms of blood distortions were fairly
common.
