A summary of these lantern slides may be put in this form:— 
The flying machine and the wave propelled vessel each consist of 
two parts, viz., the float and the propeller ; each of these is capable 
of infinite variation, The addition of more parts tends to defeat 
the objectin view. The object in view is knowledge. Knowledge 
of our neighbours and surroundings to dispel the dark clouds of 
prejudice and oppression.
