The second part of this paper, in which numerous references to 

 the literature are given, is a careful criticism of the unitarian theory. 

 The author points out that this theory, which is concerned with a 

 morphological question, depends chiefly, not on morphological findings, 

 but on epidemiological and cHnical proofs. The evidence obtained 

 from mixed infections is against the unitarian theory, and in such cases 

 faulty staining may lead to fallacious conclusions.

The causes and diagnosis of recurrent fever caused by Spirochaeta 

 recurrentis axe discussed with a short note on treatment and a report 

 of cases in Panama. 



There are four types of relapsing fever : — African tick fever ; the 

 Asiatic or Indian type ; the European type ; and the American 



type. 



The disease in North Africa is thought to be transmitted by vermm, 

 particularly lice. The work of investigators on this head is reviewed 

 [R.A.E., B, i, 70, 235 ; ii, 90, 91, 200 ; iii, 33, etc.]. 



In Panama possible transmitters are ticks, lice and mosquitos, 

 but conditions that favour extensive spread of the disease, such as 

 war, famine, overcrowding or uncleanhness, are absent.

This report explains the method of systematic mosquito catching 

 by hand in habitations on the Canal Zone, and gives a census of all the 

 mosquitos caught in this manner in each locality from 1st February 1916 

 till 31st January 1917. The work is done by trained negroes with 

 large test tubes containing a pad soaked in chloroform. In all, 391,019
