A new form of lime-light was also exhibited, which at-

Nelson said he was very much struck with the perfection

inquired if the gases had been enriched in any way, and 
-how the light was produced with such a complete absence 
of noise. Mr. Barton said nothing was used but the two 
gases, and the effect was produced by causing them to 
impinge upon each other previous to their entrance to 
the mixing-chamber, and by the construction of the cham- 
ber itself.

pupil closer to the things with which he lives. The study 
of botany should begin with familiar plant forms and phe- 
nomena. Schools and Colleges should seek to inculcate 
a love of plants. The mere learning of names of plants

this, and in the reviewer’s opinion has succeeded admira- 
bly. Take chapter VII where the subject of buds is treat- 
ed. Here we have a short definition, and a few types are 
given. The dormant winter bud to the flower in its succes-
