A young' man (20), of Dijon, suft'ering' from intestinal 

 haemorrhage and complaining* of pains in the anal region was 

 found to evacuate large numbers of dipterous larvae which could 

 be referred to three species of Anthoviyia and one of Piophila. 

 Belladonna suppositories were without effect, but a decoction of 

 absinthe leaves had satisfactory results, though numerous larvae 

 subsequently appeared at regular intervals. After a few weeks 

 a treatment with chloroform enemata and strong* doses of thymol 

 proved effective in curing this particularly severe case of myiasis.

 Pt. I. — Parasitologij, vi, no. 1, April 191o, pp. 68-118,

Although the life-history of five of the eight ticks described in 

 this paper is already known, a completion of the records is desir- 

 able, as well as a uniform arrangement of the data collected. Of 

 three species, Ixodes j^utus, I. canisuga, and I. hexagomis , little 

 or nothing has hitherto been known regarding their biology. 



The laboratory methods employed at Cambridge University 

 proved to be satisfactory. The ticks were placed upon the ears 

 or scrotum (which were enclosed in bags) of cattle or rams, or 

 upon dogs, jackals, or smaller animals kept in specially con- 

 striicted cages. When the ticks (nymphs or larvae) were replete 

 and dropped off their host, they were transferred to wide-mouthed 

 bottles containing earth and filter paper, moistened preferably 

 with a 15 per cent, salt solution to avoid moulds. The egg-mass 

 laid by each tick was placed in tightly corked tubes containing 

 filter paper ; in the case of the larvae due attention has to be paid 

 to conditions of light and temperature. 



Extreme care in recording the data is, of course, imperative, 

 and Mr. B. G. Clarke made a daily inspection of the whole stock 

 of ticks, making notes in the reports wherever necessary. By 

 the use of narrow columns with short headings practically the 

 whole life-cycle of a species could be recorded on a single sheet of 

 foolscap. The record should indicate the time the tick remains 

 on the host until it drops oft' gorged; data relating to larvae, 

 nymphs, females and males, and their behaviour on different 

 hosts ; notes on copulation ; time required from stage to stage ; 

 time elapsing before female oviposits, duration of oviposition, 

 number of eggs laid by single females; longevity of larvae, 

 nymphs and adults under stated conditions. Special methods 

 were employed to determine the number of eggs laid by individual 

 females. 



la-odes putus feeds upon a different host as a larva, nymph and 

 adult respectively, but it has proved impossible to determine the 

 duration of feeding under experimental conditions. Besides the 

 data mentioned above Prof. N'uttall describes the results of a bite 

 from this tick from personal experience.
