The |)olyiiiorphoiiueleiir eorpuseles are reiimrkuble for the variety of tlieir granules. In 

 Plate XVI 1. will be observed three varieties in shape, small round, ovoid and rod-like, 

 together with transitional sliapes between tlicsr two extremes. Tliere is also a form with a 

 round nueleus and granules of various sizes eolleeteil often to tile periphery, these usually are 

 baso|)hile and stain a deep bhie-jiurple though rarely they appear as eosinophile. I'late

There are lymphocytes of mueh the same appearanee as those in human blood. 



Contnirv to the usual teaching, I find i" object lens sutlicient when searching for the 

 trvpanosomes in the blood of the averaged sized bird and fish, and \" for trypanosomes and 

 lliilti riiliinii in mammalian blocjd. This, of course, is a great saving of labour, but is oidy 

 satisfactorv when the obst rver knows exactly wli:it lie is looking for. 



Parasites 

 found 



Su.M.MAKY OF I'aK.XSITKS FoUXD 



Trypanosomes were found in the mule, four species of fish and two species of birds, as 

 well as in the case of human trypanosomiasis already mentioned. 



The blood of the shilbaia {Schilhc in)/.sliij<, Enfrojniis nHoficus) was frequently examined 

 without success, and two specimens of the karesh fish [MormiirKx) with the same result. 



Filiirid- Were found in five species of birds, IIn/li rii/iinn in eight, and a new Hccmumteha, 

 somewhat resembling H. Zkiiuitmi, in one. 



The guinea-fowl {Xniiilihi /ill/orlii/iirfi.i) seems to be very liable to blood parasites, as 

 in one slide I found llnlli riiUmn, an Ifa niniiKcliii and two types of Filiirifr, as well as the 

 object delineated in I'late XXI., b.c. The latter, 1 am informed by Mr. U. Muir who made 

 these drawings, occurs in the corncrake in Englaml, but 1 am unable to give any explanation 

 of it, and merely append the drawing. Length varies from 50-58/1 and it occurs plentifully.
