62 . Professor Halford. 



CONCLUSION. 



I have first to thank Dr. 0. V. Lawrence for having 

 so constantly assisted me in the examination of the 

 blood after snake poisoning, and for noticing the time 

 of the appearance of the corpuscles shown thereon, and 

 ascertaining their magnitudes ; also, as the Appendix 

 shows, his records of many experiments I made of 

 injecting poisons, &c., into the circulation. To Dr. 

 Neild I have also to give my sincere thanks for assist- 

 ance in experiments with chloroform, morphia, ammonia, 

 &c. To Mr. Charles Price, also, I am indebted for great 

 and willing assistance in the experiments I have recently 

 made.
