A Few Words for the Egg- Collector. 



The following extract taken from an ar- 

 ticle bj' J. M. W., of Norwich, in an old 

 "Ornithologist and Oologist" will answer 

 the queries of m^iny correspondents: 



Why do you collect eggs? Do you live 

 in the heart of one of our great cities, with 

 few chances afield, and collect through the 

 mails by purchase and exchange? Do you 

 heap eggs together as curiosities or orna- 

 ments to show to friends, or to equal and 

 eclipse the collections of A and B? If you 

 are influenced by these motives, or situated 

 as above indicated, stop where you are! 

 Trouble the birds no longer and turn your 

 attention to bric-a-brac. You are on a 

 lower plane than the crows, grackles and 

 jays who destroy eggs through inherited 

 instinct and appetite. But if you take the 

 field yourself, in search of ruddy health, 

 with a passionate love for your pursuit, 

 with no love of notoriety, and without ever 

 a thought of rivalry, then we may not con- 

 demn you. Furthermore, if you, hope by 

 comparison of sets and by observations on 

 obscure breeding habits to add a few grains 

 of information to our humble science, go 

 on, yours is no unholy work. 



Parasites, What Are They ? 



For every new subscriber you may send 

 us for the Young Oologist, we will give 

 a copy of our new Hand-book, 



Can any of the readers of The Young 

 Oologist who have studied the subject, 

 give me some information on these bird 

 parasites which I have found in various 

 parts of the bodies of birds, notablj' in 

 owls. 



The first case which came under my 

 notice was that of a Rosy Finch ; on open- 

 ing body to examine the stomach I discov- 

 ered on the side of the heart a peculiar 

 mark, thinking it a mere wrinkle of the 

 pericardium, but on closer examination 

 found it to be a small white vporm buried 

 in the tissue of the heart, in an S shaped 

 trench. It was about four-tenths of an 

 inch in length. 



During the present winter I have found 

 them on several occasions in the heads of 

 owls, being eriibeded between the eyeball
