3. The proportion, and relative development, of the different organs 

 or parts of different animals.

On July 29, 1893, the jubilee of the Rotharnsted experiments was 

 celebrated at a meeting held at Harpenden and presided over by the 

 President of the Board of Agriculture. A granite boulder, with a 

 suitable inscription, was erected in front of the laboratory, a portrait 

 of Sir John Lawes, painted by Mr. Hubert Herkomer, was presented 

 to him, and framed and illuminated addresses of congratulation, 

 signed by the Prince of Wales on behalf of the subscribers to the 

 fund, were presented to Sir John Lawes and Dr. Gilbert. A piece of 

 plate was also presented to Dr. Gilbert, upon whom her Majesty the 

 Queen subsequently conferred the honour of knighthood. Addresses 

 from a number of scientific and agricultural societies, both English 

 and foreign, were presented. The subscribers to the Jubilee Fund 

 included societies and individuals in the United Kingdom, Austral- 

 asia, Canada, India, Mauritius, Austria, China, Denmark, France,
