Having then (if our data are correct) found that this strong relationship or cor- relation exists, the question arose as to what is the meaning of it.

There are three possibilities:-

"natural" (1) That it is a pure accident due to the fact that blackwater has a mode at 9 a.m.-12 noon. This possibility could be eliminated by examining a number of cases where the last dose of quinine was taken, say, at 9 a.m.-12 noon. If, then, the mode of blackwater correspondingly shifted, say, to 12 noon-3 p.m., the evidence for the causal action of quinine would be very strong.

(2) That the modes of quinine and blackwater are both determined by sobie unknown cause. We are unable to suggest any such cause.

(3) That the correlation is one of cause and effect.

The data at our disposal were too few, from the incompleteness of the records, to enable us to solve this very important and long discussed question of the relation- ship of quinine to blackwater, but we believe that by the method adopted by us in this paper when new and accurate data are available (if the second possibility can be excluded), the question can now be settled.

On the peculiar morphological appearances of a malaria parasite.—These forms resembled in some respects those described by myself in a previous paper as P. tenue. This latter, which I considered to be a new species of malaria parasite. has by some authors been regarded as a variety of the malignant tertian parasite, by others as a variety of the simple tertian parasite. It is of interest, therefore, that the peculiar forms described in this paper occur in association with quartan, but it is impossible at present to say whether they are quartan forms or not. is also of interest that three subsequent blood specimens from the child who fur- nished the original P. tenue specimen showed many quartans (with a single simple tertian parasite in one film).

It

A further peculiarity in these specimens is that forms occur in which chro- Sneh matin alone and no protoplasm of the parasite body exists on the red cell. appearances have, so far as I am aware, not hitherto been recorded. Their mean- ing is at present doubtful.

Sir Alfred Jones Tropical Ward. This ward of ten beds, in a new separate block in the Royal Infirmary, is close to the new laboratories of the school Attached to it is a well-lighted clinical laboratory capable of accommodating nearly fifty students. The facilities now at the disposal of students of the school for continuous clinical observation and for laboratory examination, and for being taught, are an immense improvement on previous conditions. I feel certain that students will readily appreciate the advantages. I have been appointed Physician-in-Charge of the ward, and Dr. W. T. Prout, C.M.G., has been appointed Assistant to the Physician.
