 present time in minutes before biting began. 



" Two lasted for an average of 1^ hours, three for one 

 hour, the rest for less than an hour. In the case of each 

 of the three first-named preparations (Nos. 1, 2 and 3) one 

 mosquito bit before the expiration of 10 minutes during 

 one test, although general biting did not begin till long 

 afterwards and all the mosquitos were hungry. In taking 

 the average figure, these three results have been omitted, as 

 also one test in which Lawson's pomade remained effective 

 for 155 minutes. 



" The following is the detailed list and the figures, as 

 given, fairly represent the relative average efficacy of the 

 different preparations : — 



(1) Lawson's Mosquito Pomade . 89 Consistency good. 



Irritation percep- 

 tible when fresh but 

 transient. 



(2) Cassia, camphor and soft-para- 87 Consistency fair.
