condition of chicks and favors ravages of disease. Chicks should 
he fed from troughs and watered from fountains. Solutions of 
permanganate of potash, carbolic acid and other similar drugs 
have given us no good results. We have succeeded in saving 75 
per cent, to 80 per cent, of the hatches where we kept constantly 
before them a solution of sulphocarbolates of zinc, calcium and 
sodium with 1-10,000 bichloride of mercury, using citric acid as 
an aid to dissolve the mercury. Later we have tried the three 
sulphocarbolate compounds mentioned with the addition of sul- 
phocarbolate of copper, and at present it appears to be a good sub¬ 
stitute for the mercury.

Figure No. i illustrates a drawing through an ulcer of the 
caecum due to the coccidium tenellum (from a case of coccidian 
white diarrhoea). A, the muscular coat; B, remnant of one of 
the glands ; C, the degenerated, disintegrating mass, complete 
destruction of the mucous membrane; magnified ioo times. 
Figure No. 2 shows a higher magnification of the above in¬ 
dicated by B; magnified 900 times. This shows various stages 
in the life cycle of the coccidium tenellum. A, the cocyst ; B, 
first stage of the sporoblast ; C, first stage of the sporozoit; D, 
the schizont stage showing the merozoites, these are surrounded 
by a disintegrating cell mass; E, one of the polymorphonuclear
