THE IIORSK IN MOTION. I 19 



necessary transfers from the originals, while they reproduced accu- 

 rately all the defects of the original photographs, reproduced them 

 with diminished sharpness, and these methods were abandoned. 

 Under the direction of the Heliotype Printing Company another 

 plan was adopted. From the original photographs, by the helio- 

 type process, copies were produced on gelatine magnified, and prints 

 taken on Bristol board in blue ink in the same manner as 

 in the ordinary heliotype process. These prints, with the originals, 

 were put into the hands of artists skilled in drawing on wood for 

 engravers, who drew them with a pen in india ink, under careful 

 supervision of the writer, so as to preserve the outlines as they were 

 rendered by the camera and avoid reproducing the blotted defects 

 of the originals. These drawings were then reproduced on stone by 

 the camera, reduced to their original size, and the prints given in the 

 volume were printed from these stones as in ordinary lithography. 



They cannot fail to be of great advantage to artists, especially 

 those who would perfect themselves in animal drawing, and that 

 acknowledged difficult branch of their art, animals in motion. 



They and the public generally are greatly indebted to Mr. Stanford 

 for the enlightened liberality with which he has pursued this costly 

 investigation, and given its results to the public without any prospect 

 of pecuniary advantage to himself. 



It will be observed that some of these pictures are so nearly alike 

 that at a superficial view they appear the same ; but it is almost impos- 

 sible that the times in which any two should be photographed should 

 coincide, and there will be found no two exactly alike ; and the near 

 approach to the same posture proves the universality of the law in 

 which all the paces are performed. 



In some of these plates there are but four pictures; the fifth, owing 

 to some serious defect or failure of the apparatus altogether, is 

 wanting.
