gas engines, under special conditions, where the high price 

 would not be prohibitive, would otfer a very interesting 

 study. It does not seem impossible that a gas so active 

 and so easily stored might be exploded with air in a pneu- 

 matic gun to give an additional impulse to the projectile. 

 The laboratory experiments which have been described 

 may perhaps serve as a guide in some directions to manu- 

 facturers, but they cannot settle the commercial details 

 upon which the success of the new enterprise depends. 

 Much further study and tests upon a larger scale, with 

 the improvements suggested by prolonged trial, can alone 

 decide whether the new illuminant is destined to supplant 

 older industries built up slowly and surely by the persist- 

 ent efforts of hard-working and skilful men. 



Two Shrews of the Genus Sorex, new to 

 New Brunswick. 



By Philip Cox, A.B., B.Sc, Ph.D. 



It may be of some importance to those interested in 

 the distribution of small mammals to learn that two 

 species of the genus Sm^ex have lately been found in New 

 Brunswick, which are not only new to Provincial lists, 

 but the occurrence of one of them is more than a surprise. 



Sorex Richardsoni, Bachman, a boreal form of the North- 

 West and Northern portion of the Central Plain, has not, 

 so far as the writer can learn, been reported east of North- 

 ern Minnesota. That it should turn up on the Atlantic 

 side of the continent could hardly have been suspected i 

 yet the writer collected it here in the winter of 1894-95, 

 Indeed it is by no means rare on the intervales and low 

 forest country adjacent to the St. John Kiver, in Mauger- 

 ville, Sunbury County.
