869' Haemacytometer, Miescher's (Zeiss). Counting chamber in combination with a specially 

 constructed mixing pipette. With principal gauge marks for dilutions of y^, p^, - s ^ Tll 

 and auxiliary marks for accurately estimating any existing faults in the graduation. 



In case 



861' Mixing pipette alone . . . . . . . . . . . . . . each 



862' Fleischl's Haemoglobinometer for ascertaining the amount of haemoglobin contained in the 

 blood. 

 This apparatus possesses the following points of superiority : 



1. The instrument is convenient and easy to manipulate. 



2. It is adapted for determining the relative proportion of haemoglobin with rapidity 



and precision. 



3. A very small quantity, viz. a single drop of blood suffices to perform the 



determination. 



4. It is of an almost unlimited durability. 



Complete directions are supplied with each instrument . . . . . . each 



863' Six spare capillary tubes . . . . .'.' . . . . . . . . ,, 



864 T One spare comparison chamber 



(When ordering extra capillary tubes the number stamped on metal holder must be 

 given, as each instrument is calibrated to suit capillary tubes of a definite capacity).
