the leucocytes and proleucocytes increase up to 80-90 per cent. 

 Leucocytolysis and phagocytolysis occur, causing the liberation of 

 ferments and intracellular antibodies.

 Of the various animals capable of polluting water and food at 

 Petrograd cockroaches occur in great abundance. An examination 

 of the intestine of Blatta {Periplaneta) orientalis showed it to be heavily 

 infested with flagellates and other organisms, including Oikomonas 

 sp., Monas sp., Nyctotherus ovalis, Oxyurus diesingi, Blasiocystis, 

 Lophomonas striata, L. hlattae and Entamoeba hlattarum. 

 The females carry the highest percentage of infection.

Flagellates of the type of Herpetomonas and spirochaetes have 

 previously been described from the latex of species of Euphorbia 

 [R.A.E., B, ix, 58, 106, 120]. During the hot summer of 1921 in 

 Italy, definite trypanosomes and a series of other forms have been 

 found that have completed the earlier researches. The types of tr^^- 

 panosome discovered are described, the developing stages resembling 

 those of T. cruzi or of Cystotrypanosoma intestinalis , which was 

 described by Roubaud from a species of Lucilia in French West 

 Africa. Although having certain affinities with the trypanosomes of 

 insects described by Chatton and Alilaire, Patton, Roubaud and others, 

 it also seems to offer some resemblances of development with certain 

 trypanosomes of vertebrates. It is therefore treated as a new species, 

 and named T. euphorbiae. 



From examinations of many insects collected from plants in 

 the Botanical Gardens of Florence, lists have been compiled of those 

 that harboured flagellates in their digestive tracts. Franga, in Portugal, 

 suspected Stenocephalns agilis of being the transmitting agent of 

 flagellosis of Euphorbia because he found it on Euphorbia plants and 

 discovered flagellates in its intestine, salivary glands and proboscis. 

 The same discoveries have not been made in Italy, where, however, 

 it has been shown that many other insects harbour flagellates in the 

 same organs. In fact, some of the phytophagous insects captured 

 near the two species of Euphorbia known to be infested with trypano- 

 somes harboured Herpetomonas or Crithidia, though none of them 

 showed trypanosomes. Among the non-phytophagous or only 

 occasionally phytophagous insects, however, a certain number harboured 

 in their digestive tract not only Herpetomonas and Crithidia but 

 trypanosomes also. In particular, trypanosomes are recorded from 

 certain Muscids and from Anopheles maculipennis.

 Further evidence is adduced to show that Glossina palpalis can 

 occur and breed permanently in certain districts of the Belgian 

 Congo at considerable distances from water [cf. R.A.E., B, viii, 68].
