to do with the case, and it is not stated how the other two were collected. 

 It is probable that D. venustus is found in Oregon where Temple's 

 cases occurred. The author states from personal experience that it 

 is by no means an uncommon thing to find ticks attached to the hair 

 after a day in the bush in the Western United States, and that the 

 cases reported by Todd and Temple where ticks were found attached 

 to the head, might be due to coincidence. No particular species of 

 tick appears to be concerned, since D. venustus in British Columbia, 

 and Ixodes pilosus in South Africa both appear capable of inducing 

 the same afiection. That the disease is a definite affection, however, 

 has been rendered certain by the experimental results obtained by 

 Hadwen on sheep and by Hadwen and Nuttall on the dog, but as 

 regards transmission, the only clear experimental evidence that exists 

 is that implicating Dermacentor venustus.

The author describes the larva of the bamboo-breeding Anopheles 

 {Myzorhynchus) asiaticus, which he obtained from a cut bamboo at 

 Ginting Simpah, F.M.S., at an altitude of 1,500 feet. One full-grown 

 larva was observed to remain for about four weeks without pupating ; 

 the author placed it in a bottle and found that while kept in the 

 light for another week it still remained in the same state : when, 

 however, it was put in the shade it pupated immediately and two days 

 later the imago had emerged. It seems that light has an inhibitory 

 action on the pupation of this species, a suggestion that is in keeping 

 with the fact that larvae in the cut bamboo always took refuge in 

 the dark end. Light seems to have no inhibitory influence on the 

 early growth of the larva ; three very small larvae were kept in a 

 bottle in the light and grew very well ; they pupated after 35, 41 and 

 43 days respectively.

The author has worked for some time past on the Tabanidae of 

 Brazil, particularly with regard to the earlier stages of these insects. 

 Eggs which the author believed to be those of Tabanids were found 

 on leaves at the edge of swiftly running water ; the larvae were not 

 obtained when the water was dredged, and it is probable that they 

 develop underground in the soft, wet earth. The larvae reared from 

 the eggs obtained are described ; they are very active in their move- 

 ments either in water or on dry land ; they will not live long, however,
