Experiments indicated that pH can be a significant factor in the stability 

 of some amino acids. A sample of Meroenaria showed that a sample heated dry 

 showed little or no reaction, in contrast to those heated in presence of 

 water or water vapor. In subsequent experiments changes observed in Recent 

 shell fragments were analogous to and duplicated changes found in natural 

 series of fossils. To study the kinetics in more detail, modern shell was 

 heated at 165°, 140°, 125°, 105°, and 90° for periods of 1 hr to over 3 

 months. Amino-acid ratios changed systematically with time of heating, in 

 a fashion analogous to fossil shells. - J.L.M.

Estimates of probable yield were made by 2 methods. The area was contoured 

 and the area covered by each contour was measured by planimeter. This was 

 multiplied by the average density of quahogs as determined by sampling. This 

 method produced an estimate of 1200 bu. The second method was to multiply the 

 total area by the mean of all samples. This gave an estimate of 1400 bu. 

 Actual production was 1525 bu. - J.L.M.
