" In conclusion, it may be remarked, that however paradoxical 

 the history of the red jDarticles may be, still, that of the blood gene- 

 rally is in many respects equally so. As we can only expect to ob- 

 tain a knowledge of the physiology of the corpuscles by the multi- 

 plication of observations, it is especially desirable that persons re- 

 siding abroad should avail themselves of opportunities of examining 

 the blood of such animals as are not easily to be seen alive in this 

 country. Among the birds, it may be mentioned that an examina- 

 tion of the blood of the different species of Temminck's orders Ani- 

 sodactyli and Inertes is especially required ; and when made, it is not 

 improbable that some interesting results may be obtained."
